ATS Transmission Package for Dodge (2003-09) 545RFE 4X4 Hemi, Stage 1

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. 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.
