The 42RLE is one of our best selling transmissions. This unit is used in Dodge Dakota, Durango, Ram and Jeep Grand Cherokee's with automatic platforms. Because of the 42RLE's popularity we knew that rigourous testing in multiple applications would be necessary to ensure flawless use regardless of the vehicles model. Over years of testing we have been able to pinpoint flaws in the transmissions design. Our performance upgrades have been developed to stabilize the transmissions weakness and increase its overall performance and torque handling.
What is the difference between the 42RLE, A518 and A727 Transmissions?
The 46RH, also known as the A518 was used from the early to mid 1990's and features a hydraulically activated governor as well as a torque converter lockup, which it's predecessor, the A727 did not have. The powerful 42RLE is a later version of the A518 and made it's debut in 1996. The "E" designating the electronic, rather than hydraulic (as seen previously in the 46RH) governor that was newly implemented.
