Sometimes, the factory 68RFE in your 2015-2018 Ram Cummins 2WD just doesn't cut it. Why not put an Allison behind your Cummins engine! The Allison transmission is known for its strength and durability and in the past, installing an Allison in your Ram was an absolute headache. Not anymore! ATS has developed a complete kit with everything you need to swap your 68RFE for a built Allison Stage 4 Transmission.

 

ATS Diesel has engineered the first fully integrated Allison transmission swap for Cummins powered vehicles. Backed by our proprietary TRANSLator technology and our exclusive, patent-pending Allison to Cummins Bellhousing, the ATS Diesel Allison Swap offers complete factory functionality from your late model Ram; from push button start to tow/haul mode, electronic range select and electronic transfer case functionality. Our revolutionary new TRANSLator can-bridge module allows the Allison TCM to communicate with the Ram ECM and offers a seamless integration of all factory options on the truck with a nearly plug-and-play installation. Our exclusive, patent-pending Allison to Cummins Bellhousing allows a perfect factory match between the Allison and the Cummins with no additional fabrication required. The all-new ATS Diesel Allison Conversion Kit includes all necessary hardware and software to install an Allison LCT1000 behind your Cummins.

 

For those of you that are not satisfied with the Dodge automatic transmission behind your Cummins engine, the Allison 6 speed swap is an excellent alternative. If you’re looking for increased reliability and a transmission that will hold under the power of the Cummins you will find that the Allison LCT 1000 built by ATS is superior to the factory transmissions offered by Dodge.

 

Due to the nature of the Ram 68-RFE having very small shafts, gear sets and clutch packs, the factory Ram transmissions require very extensive modifications and expensive hard parts to compete with a rebuilt ATS Allison 1000. These parts include the hydraulic pump, clutch packs, shafts, and torque converter modifications to strengthen it to reliably handle the massive torque of the Cummins engine. The Allison 6 speed automatic transmission comes from the factory with large shafts, clutch packs and gear sets. This gives the Allison a direct advantage over the 68-RC Dodge transmissions. The 69-RC has similar size clutch packs, shafts and gear sets as the Allison, however, it does not have an ideal gear split so the 69-RC always seems a bit “clunky” and does not handle increased power levels well. The 69-RC transmission also relies on engine derate that happens between all gear shifts, this engine derate makes for a very poor shift quality and massive drivability complaints. When all costs are taken into consideration with regards to what it takes to upgrade all of the small and under designed parts of the Dodge transmission, the upgrade to the Allison conversion could be argued as the most cost effective solution.

 

There are a few questions you should ask yourself when weighing the decision of whether to go with an ATS upgraded Dodge transmission or to replace it with an Allison conversion:

 

Is your Cummins engine modified?

 

Do you tow heavy loads for long distances?

 

Do you have over-sized tires?

 

Does your vehicle appear to be under stress with the workload you are putting it under?

 

If you answered yes to any of these questions you are a prime candidate for the Allison transmission swap.

 

The 68-RFE transmission has a fantastic gear split between its 1st through 6th gears providing an almost perfect gear ratio change. The torque converter is a PWM design allowing for precise application of the converter clutch which provides a smooth shift. Unfortunately, this is where all praise for the 68-RFE ends. The 68-RFE transmission was clearly designed to be the least expensive to manufacture. As a result, there are many elements that must be upgraded in this transmission to make it reliable and handle higher power levels. Even the transmission case is cheaply designed and must be reinforced with a large aluminum pan and transmission brace over the top to keep if from cracking in half. The 68-RFE internals are actually larger versions of those found in a Dodge Caravan transmission that originally debuted in 1989. Chrysler used this basic design and adapted it to be used behind their gas engines calling it the 545-RFE. They then made a few parts in the 545-RFE transmission a little larger again to then be used behind the Cummins which eventually became the 68-RFE that we know today. The 68-RFE can be rebuilt with upgraded parts making it a great shifting transmission but it is limited because of the small clutch packs, gear sets and shafts that make up the transmission. At the end of the day the 68-RFE is just a Gas transmission that was placed behind the massive 6.7L Cummins engine. Similar to the 48-RE, the money spent in strengthening the internals of the 68-RFE is likely better suited to be invested in the Allison conversion. If you were to spend the money to upgrade the internals of the 68-RFE, you would still be left with a transmission that has clutch packs, gear sets and shafts that are nearly half the size of those in the Allison. Another one of the benefits of the Allison is it learns your driving style, different drivers, power levels, habits etc, the Allison TCM will adapt to them all providing a smooth shift through all the ranges. Tap shifting capabilities and tow-haul are all still present as well. For the 6.7L Cummins you can use the factory shifter and for older trucks you can purchase a new shifter, which can be installed in a matter of minutes and still has all factory functionality. Overall the Allison can handle more power, with more functionality and longevity than other transmissions. An Allison swap is a solid choice whether you want it for your daily driver, heavy towing, or want to take your truck down the sled pulling track. What would be the best all around transmission for a person that tows, wants to use the power of their high horsepower Diesel, is looking for reliability above all and still would like to have the ideal shifting transmission? The Allison 1000 is the best option that is now possible behind the Cummins engine! This does not mean you can take just any Allison 1000 transmission and put it behind the Cummins engine, as great as the Allison transmission is; the stock Allison transmission does have it’s limitations and downfalls. The great news is the Allison can easily and affordably be upgraded to handle a very high level of abuse and high horsepower while providing reliability and longevity.

 

In order to properly transplant the Allison transmission into the Dodge Pickup there are many areas that need to be addressed. How the transmission is adapted to the engine, transfer case, cooler line adaptation, manual linkage, fill tube, transmission electronic control system, and driveline modifications are the basics. This is another area where ATS shines, we have taken the time to cast a “Factory fit” bell housing and extension housing to replace the GM ones found on the Allison. The new ATS castings allow the Allison to transmission to bolt directly up to the Cummins engine with out any engine modifications. Yes, this means you no longer need a different engine adapter plate, different starter, flex plate and most importantly you no longer have to grind material off of the engine block to make clearance for the starter. All of the factory wiring and fuel line brackets bolt to the original bell housing bolts as it came from the factory. The transfer case bolts up the back of the transmission and it’s positioned perfectly allowing the drive lines to line up properly.

When converting from a 68-RFE transmission to the Allison depending on the year of the truck the engine calibration has to be re-flashed to a 68-RC or 69-RC calibration. This is as easy as using the factory Chrysler scan tool and loading the original factory calibration into the truck. Once this step has been performed you can apply aftermarket tuning to your truck as you have in the past if you are after higher power levels or other engine tuning modifications. The other area where the ATS Allison conversion shines is in our electronics package. The Translator module bridges the gap between the Transmission Control Module (TCM), Body Control Module (BCM) and the Engine Control Module (ECM). When the factory Chrysler transmission is removed from the truck the BCM and ECM no longer receive information from the TCM, this causes a huge problem with the operation of the truck. A few of these issues are: loss of cruise control, loss of factory remote start, loss of factory rear view camera, speedometer out of calibration, you can not shift to 4x4 Low range, Loss of Tow Haul mode, Loss of Tap Shafter, Loss of PRND 1,2,3,4,5,6 indicator on dash. The ATS Translator module bridges all of this information making EVERYTHING work as it did from the factory. All functionality works perfectly allowing the truck to drive and operate as it did the day it rolled off the showroom floor!

 

SHIPPING POLICY - Due to the size and weight of transmissions, they cannot be shipped through traditional couriers, such as UPS, FedEx, USPS, etc. and MUST be shipped via truck freight. We do not offer free shipping on transmissions, however, we do offer a very competitive rate charged at checkout checkout. Once your core transmission is ready for pick up, you just need to give us a call or send us an e-mail with your original order number and the core tag on the transmission, and we can supply you with a quote on the return shipping as that is not covered in the original shipping cost. Otherwise, we give you the option to coordinate the return shipping on your own and independently pay your courier of choice. As always, if you have any questions, give us a call or send us an e-mail.

Versatile Room Divider With Easy Assembly and Strong Coverage
Size: 3 Panel 12FT W
I picked up this Siebwin 3-panel folding room divider mainly for privacy and room separation, and overall it works very well. Assembly is very straightforward, and the divider can be set up, taken apart, and stored without much effort. The fabric quality feels good, and the frame construction is stronger and more stable than expected. The support tubes especially feel well built and help keep the divider standing securely. One feature I really liked is the flexibility of the design. The panels can be used together as a complete divider or separated depending on the setup and available space. That makes it much more versatile for different room layouts or temporary privacy needs. The coverage is also very good, and the size matches the manufacturer’s description accurately. The fabric blocks light and background visibility well enough to provide solid privacy without feeling overly heavy. The wider feet also help improve stability compared to thinner folding dividers. Another positive detail is that everything arrived complete with no missing parts or damaged pieces, which made assembly much easier and faster. Compared to cheaper privacy screens, this one feels more durable and easier to customize depending on the situation. In terms of value for the money, it feels like a very practical and worthwhile purchase considering the size, flexibility, and build quality. Overall, a versatile and well-built room divider with easy assembly, strong privacy coverage, stable construction, complete included parts, flexible panel configuration, and excellent everyday functionality.

Stable, flexible in deployment configuration, creates true privacy and looks great.
Size: 3 Panel 12FT W
This is the second room divider panel I have installed, and there are several features about this one that I like much better than my older one. The fact that there are no gaps and that the material is thicker means you get more privacy or more hiding power, if you wish. My older divider has vertical spaces between each of the panels and the panels are half as wide as the Siebwin panels, so there are many vertical spaces. The Siebwin divider really creates privacy. Another feature that I really appreciate is that the legs are wider and stand off from the floor. On my older one the legs are flat and they're rather awkward to adjust because they create more drag on the floor. The feet on the older one also loosen if you turn them counter clockwise, so adjustments of configuration that require the feet to be moved are more complex. The older divider also must be deployed in a zig-zag fashion because he feet are not as wide, but this new one can be deployed and stable in a straight, an "N" shape or an arc. They are both the same length, but because the older one must be use in a zig-zag deployment it doesn't reach to the length of the new one. The Siebwin divider definitely costs more at $103.48, but it sports several features and advantages over the other brand, so it does a better job and is worth the extra cost.

Easy to assemble, does the job, material is shiny nylon and shows creases, minor defects, sloppy
Size: 3 Panel 12FT W, Size: 3 Panel 12FT W
The Siebwin room divider is a good idea, and for the price, it mostly delivers on the intended functionality. I ordered the 12 foot, 3-panel version mainly to hide an unfinished basement storage area that had become an eyesore. It works well for that purpose and gives the space a cleaner appearance without spending the kind of money that more decorative dividers or custom partitions cost. If you need something temporary, portable, or mainly functional, this is a viable option. There are a few limitations that became obvious during setup and use. The first thing I noticed was that the weld quality on some of the metal poles is fairly sloppy. Once the cover is installed, you do not really see it, but up close, it does not look especially refined or professional. The blackout material also is not a matte canvas style fabric as I expected. It has more of a shiny nylon appearance, and the creases are fairly visible. Being that it’s more of a nylon, I’d be hesitant to try steaming it to remove the creases. However, the creases do not matter if you are using it in a basement, dorm, or shared room, but for photography, video work, or a professional office setting, the appearance could be disappointing. The fabric is thick enough, though. It blocks visibility well enough, but strong light behind it still shows through to some extent, nothing deal-breaking. Also, my fabric appeared to be slightly defective. The hook and loop strip on one of the bottom sections was off-center and couldn't be totally attached because it was lined up with one of the legs. I originally hoped to use this as a video backdrop, but I will probably end up replacing the fabric with a proper green screen or canvas material while continuing to use the frame itself. For now, it does a good job of covering my basement junk. Assembly was actually easier than I expected and took roughly 15 to 20 minutes. The longer vertical poles are tethered together similarly to tent poles, which made setup straightforward and fairly intuitive. The shorter horizontal pieces slide and snap together to the top and bottom of the vertical assembly. After each section is assembled, the divider panels connect together with metal plates and two knurled screws (at the top and bottom), so no tools are really required. A few screws were difficult to start because paint had gotten into the threads, but once they caught, they tightened down normally. The feet install with similar knurled fasteners and help keep the divider reasonably stable. One thing to watch for during setup is the fabric orientation. There is one arrow indicator in the middle of the fabric to indicate up. However, if you need another indicator, the smaller hook and loop strip goes on the bottom while the longer strip goes on top. I realized mine was upside down right before finishing and had to redo it. I wasn't difficult to redo, despite the defect in mine. The overall design is practical and easy to move around. I do like that the panels can fold and bend into different shapes depending on the space. The widened feet help stability, although when trying to stretch the fabric tight, I noticed the poles sometimes wanted to overlap slightly at the joints. Tightening everything helped somewhat, but it still happened occasionally. The divider feels adequate for normal indoor use, though I would not expect premium durability or luxury-level fit and finish at this price point. The entire device can also be easily disabled and stored in a tote if you need it completely out of the way. It comes with assembly instructions, but even if you didn’t have them, it’s easy to build without them (save a mistake or two). In terms of value, I think the Siebwin divider mostly matches its price. Around $100 gets you a large freestanding partition with decent usability and easy assembly, but there are compromises in materials, appearance, and refinement. The defects are also off-putting, but hopefully you won't have them. Higher-end room dividers can easily cost two or three times more, so some of the tradeoffs are expected. I also noticed cheaper alternatives online, but based on the quality here, I suspect those would probably have even more issues. For practical home use, temporary privacy, hiding storage areas, or separating shared spaces, this is a good option as long as expectations stay realistic.

Works well but takes up more space than expected
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
This room divider does the job for creating a little extra privacy and was easy enough to set up. The panels feel decent quality and the wider feet help keep it more stable than some cheaper screens I’ve tried. My only issue is that it takes up a bit more room than I expected, especially with the feet sticking out. It’s still portable and folds away nicely, but definitely measure your space first. Overall it works well for separating a room or blocking off an area temporarily. i wish it came in other colors

Nice divider, serves it's purpose well!
Size: 3 Panel 12FT W
This room divider worked out very well for what I needed. I wanted a simple way to create a little more privacy and separation in a larger room without doing anything permanent, and this divider was an easy solution. The panels provide good coverage, and the black color gives it a clean, modern appearance that blends in nicely with different décor styles. Assembly was fairly straightforward, and once set up, the wider feet helped keep the divider stable on the floor. I was especially happy with how flexible the panels are to arrange. You can keep it mostly straight, angle it around furniture, or create a more enclosed private space depending on the layout you need. The material allows light to filter through slightly while still offering a noticeable sense of privacy. I’ve used it for separating a workspace area, but it would also work well in bedrooms, apartments, dorms, studios, or shared living spaces. Another plus is that it can be folded and moved without too much effort when you want to change the setup. Overall, this divider delivers a good balance of functionality, portability, and appearance. It’s a practical option for anyone needing temporary room separation without installing permanent walls or curtains.
