Hello all... I am new to the forums and appreciate all the info and help everyone provides.
I just bought a 97 TJ with a LT1 and 4l60e transmission that has quite a few problems. On the way home, the transmission started to shift from OD to 3rd at random times. This steadily got worse until it is not not holding a gear at all.
The previous owner did not change the stock shifter to one that is compatible with the 4l60e. I am assuming this could cause issues? I just ordered a new B&M for it.
I believe that the transmission may need a full rebuild, even though it has less than 600 miles on it since the previous owner had it rebuilt. It sat a lot, which probably wasn't good on it either. The previous owner also removed the speedometer, which I have read is involved in the criteria of the trans determining when to shift.
My question is, does anyone have experience with installing a 4l60e/LT1 combo and what does it take to get the transmission to work properly? Are there any PCM mods that need to occur? Any other "gotchas"? I was hoping for a basic "checklist" of items that need to occur to get the transmission installed correctly. I don't want to rebuild it only to tear it up again because I didn't correct the root cause.
Thanks for the help!
