There are several things that should be understood about the HEMI 545-RFE ATS built transmission. This transmission was originally designed to be very inexpensive to manufacture. This approach forced the original designers to cut corners in size and quality of materials that could be used.

On a positive note, the technology that is utilized in the transmission is leading edge; this advanced technology has forced the aftermarket to completely rethink how to modify and control the transmission so that it can still perform and remain reliable while modifying the engine to have higher power levels over stock.

ATS has developed a combined technology utilizing recalibration of the hydraulic circuits inside the transmission, including revamped accumulator rates, reprogrammed clutch to clutch apply and release timing, and line pressure rise rate to perfectly match the torque output of the engine.

These enhancements, along with other key hydraulic modifications which ATS makes, must be done to ensure the clutch packs have the correct apply and release rates when commanded on or off. As well, the transmission hard parts have many limiting weaknesses which do not allow for increased power levels over stock. Specifically, the light duty shafts and hubs, and the low one-way sprag; these hard part weaknesses must be addressed.

Some of the areas that are addressed by ATS to complete the performance transmission upgrade package are listed below, starting at the front of the transmission working towards the back.

Because of the combined combination of technologies we have used to redesign this transmission to handle extreme power levels we now offer the RFE for any application. If your looking for the best in performance, durability and over all shift quality you have found what your looking for.

Pump Assembly:
The Torque converter regulator valve has been redesigned to prevent over pressure and ballooning of the converter, along with regulating minimum converter charge for proper cooling and lubrication of the transmission gear set. This redesign also eliminates the common problematic valve and bore ware that is usually the first cause of high mileage transmission failure.

The main pressure regulator circuit is modified to enable a broader range of pressure that can be commanded from the TCM. This allows the pump to lower line pressure when the engine is at low loads and more responsively raise pressure above stock to react with increased engine torque and horse power levels.

Rotating Clutch Drum Assembly and Clutch Packs:
Clutch modifications are generally one of the most impactive and important items that can be upgraded in any transmission. In the case of the 545-RFE transmission, there is little room for additional clutches so modifications must be done to pressure plates providing increased clutch surfaces. The clutch surface area are listed below.

  • The Under Drive (Forward) clutch pack surface area is increased by 21 percent, using single sided clutch plates.
  • The Over Drive clutch pack surface area is increased by 17 percent, also using single sided clutch plates, this allows for better clutch control when overdrive is used at higher power levels.
  • The 2C clutch pack surface area is increased by 34 percent, using double sided frictions.
  • The 4C clutch pack surface area is increased by 34 percent, using double sided frictions.

The weak mechanical low one-way sprag is replaced with a stronger roller clutch design that used a cam and roller system. The factory low sprag not only has a very weak torque capacity, but it also fails from lack of proper lubrication. The stronger low roller clutch design used by ATS prevents the higher mileage failure associated with the sprag-type clutch.

Although the new cam and roller low roller clutch design is much stronger it still has imitations; the Co-Pilot transmission controller contains a direct function to route power around the mechanical clutch when extreme power levels are sensed. You will read more about this in the Co-Pilot section below.

Valve body:
The valve body is considered the nervous system of the transmission; the valve body is responsible for converting the electrical signals from the TCM into hydraulic actions. The 545-RFE uses a non-synchronous, clutch-to-clutch design. This means that the shifts from gear to gear must be timed perfectly thereby releasing and applying a friction clutch to achieve an flawless shift.

Because of the sensitivity of the hydraulic circuits, we heavily modified many areas of the valve body. Hydraulic oil flow is ported to certain clutch packs where additional pressure is needed. The accumulator piston seals have been redesigned to ensure hydraulic pressure integrity.

The accumulator plate is made of high-grade material to compensate for the additional pressure that the accumulator pistons and springs exert during heavy power situations. Also, the ATS 545-RFE valve body can be purchased separately and installed in a stock transmission for increased transmission capacity.

Shafts:
There are three shafts in the 545-RFE that are of some concern. The forward hub/shaft, Intermediate hub/shaft and the input shaft. The forward hub/shaft is reinforced to eliminate breakage. The Intermediate hub/shaft is reinforced to eliminate breakage.

Case and Pan:
The main transmission case does not require a lot of conditioning aside from a few small hydraulic modifications to allow for proper oil flow. The case is sealed using an epoxy base sealer to inhibit oxidation and corrosion caused by nasty road conditions. At higher power levels the transmission case does need to be strengthened.

This is a simple fix that is taken care of with the optional heavy-duty transmission pan, which was designed in part to act as a girdle, thus eliminating the flex in the case. The large over sized pan also provides for an additional 5 quarts of ATF allowing the transmission to run cooler.

Torque Converter:
This package comes with a Heavy Duty single disk torque converter with a Billet Cover.

Loved by both my pup and I! I can't say enough good things!!
Size: Large, Number of Items: 1
My lab puppy absolutely loves this! And so do I. My 5 month old lab puppy loves to play with us and is not so good at playing by himself. Though he is getting a little better. I use this when we need to keep him occupied or when we need a little break. I bought this for him when we first got him at about 2 months old; even then he had no problems figuring it out. Depending on how much food I put in it, this will keep him busy for quite awhile. My puppy does not usually have much of an attention span, he is always jumping from one toy, bone, or chew to another. But with this I know I can consistently depend on him being entertained for at least 15 to 30 minutes, again, depending on how much food I put in there. "Bob" as we call him, is very well made. I purchased the large one and it holds about 2 cups of food. The yellow top screws off so that you can pour the food in, there is an adjustable opening so if you want to make it harder for your dog you can adjust it and he will have to work harder to get the food out. It screws on quite tight and has never come off while my dog is playing with it even when he carries it around by the top. There is another opening towards the bottom where the food comes out that is also adjustable depending on how easy you want it to be or how big the food is that you are using. Both openings are pretty large and I have never had an issue with putting things in there. I know some people use it to put their dog's food in, as my dog is self fed I have never done that. But I do use Cheerios and all kinds of other cereals and treats but mainly I use other "special" dog foods. I buy moist and dry dog foods that look like they may taste good and use them as treats. My dog thinks he is getting treats and never knows the difference, he loves them. It's healthier than feeding him lots of treats and also a lot cheaper. Using the "Bob" not only keeps him independently entertained but also helps to tire him out. It can be a bit loud as I have tile floors but it is not that bad. It is constructed extremely well. My pup plays very rough with it, he bats it around into walls, furniture etc., drops it down steps, it has taken a beating but it has stood up to my dog's abuse, where many of his other toys have not made it. It is very easy to clean. I plan on purchasing another one for my sister-in-law's pig. She is 70 pounds over weight and hates to move around but obviously loves food. I think that putting her food inside will be just the motivation she needs. And it is so well made that I don't have to worry about giving it to her!

Favorite toy
Size: Small, Number of Items: 1, Size: Small, Number of Items: 1
This is my dog’s absolute favorite toy. When I fill it, it’ll keep him busy for up to an hour, and even when I don’t fill it, he likes to tip it around to check for missed treats quite often. It’s super sturdy, and just the right size for him (20 lb mini schnauzer).

Can't be clean but provides fun.
Size: Small, Number of Items: 1
It's well made and our pup really does like it. The only thing is, it doesn't fully open to clean it out. I wouldn't buy it again for that fact. It's tough plastic and sturdy.
