Sometimes, the factory Aisin AS68RC in your 2007.5-2009 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 Aisin AS68RC 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 Aisin AS68RC 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.

Upgrading to the Allison is the only logical choice. The Aisin 68-RC transmission suffers from many of the same shortcomings as the 68-RFE but also has its own unique issues. Currently there are limited hard part upgrades for the Aisin 68-RC and there are many areas that need to be addressed, not only for strength but for longevity. Factory replacement parts are 2 to 3 times the cost of conventional parts which drives the cost of rebuilding the 68-RC to a level that is unreasonable. For these reasons, ATS decided to focus our efforts on making the Allison 6 speed conversion affordable for anyone that needs to replace their failed 68-RC.

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.

The other area where the ATS Allison conversion shines is in ATS's 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. 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.
