The 42-RLE transmission that is used in the 2003 to 2012 Jeep was never designed to handle the abuse of after market add-ons such as over sized tires, extreme off-roading, increased power levels, higher gear ratios or towing.
The ATS modified 42-RLE has been redesigned to correct all of these problems and handle increased power levels of larger displacement engines, Super charged or Turbo charged engines, Larger tires or heavy towing.
We understand the real world abuse that this transmission is asked to do in modified applications so we came up with the fixes for it. 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 timings, 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 must be addressed.
All of these areas are addressed in our transmission to allow for increased power levels and reliability.
