    How long does the 42RLE live for?

    My Jeep just passed 238k miles and it’s time for the next transmission service. My 42RLE automatic transmission is the OG and it is still working. I have a transmission cooler, the aux mechanical fan, and it has only been up to 240° once and the fluid was promptly changed afterwards. That was...

    Transmission service manual for 42RLE (non-VLP)

    I found the trans service manual for 45RFE transmission, but I cannot find the service manual for the 42RLE. In case it matters, I have a 2005, therefore it does not have VLP. If a transmission service manual exists for the 42RLE, I would appreciate a pointer. Thanks much.

    Transmission Re-Learn

    So I believe my 42RLE is finally going out to pasture. I've been exploring multiple routes such as having a shop rebuild it, replacing it myself with a reman, etc. If I replace it myself, I keep hearing of a relearn period or program. Is there any way I can relearn it from my garage? Or would...
