    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.

Is there any way I can relearn it from my garage? Or would...
