Sometimes, the factory Aisin AS68RC in your 2007.5-2009 Ram Cummins 4WD 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 5 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!

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.

Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.

I want to live in these
Color: 01-multicolour (4-pack), Size: Medium
I bought 4 different sets of new underwear. Unfortunately these came last. It’s unfortunate, because if they had come first I would have cancelled all my other orders or returned them and ordered more of these. I never want to wear anything else ever again; these are the comfiest undies I’ve ever owned, I want to live in them. I can wear them under pretty much anything except leggings or very tight pants (but let’s be honest, I don’t wear those anyway.) They are incredibly soft and breathable, they wash well, don’t roll, keep my thighs from rubbing, are comfy to sleep in, and the colors were true to the photo. Just a heads up, they are on the thin side and just a bit see through in the rear. I’m 5’5” 140lbs and the mediums fit perfectly, they go about mid-thigh.

Extremely comfortable
Color: 02-multicolour (4-pack), Size: X-Large
These are by far the softest and most comfortable underwear I have ever owned. The leg portion absolutely does roll up as so many others have mentioned, however, I did not find that to be uncomfortable at all just annoying that they don’t stay in place. I bought these specific underwear to see if it would help alleviate HS symptoms at all. They have definitely helped with wicking moisture away from the skin. More time will tell if it’s truly helpful for HS. For now, I will recommend these. They are thin, breathable, butter soft, wick moisture comfortable and I would buy again…maybe in a different style next time. I have washed them several times and they seem to be holding up rather well so that is also of supreme importance given the cost of the item. Again, I would recommend this item and plan on purchasing more in a different style very soon.
