Just got a 91 turbo awd auto like a week ago. He sold it to me with the car on limp mode (3rd gear only). I checked for codes and not even a pulse from the diag port. I opened it and a cap had leaked and there was 12v in the circuit (shock). So I buy another 91 turbo AWD TCU on eBay and same story. So I went to the junk yard and got a 91 N/A 2.0 FWD TCU (MD750525). I plug it in and it works, at least, but there is a problem. First is good, shifts to second and it’s good, shifts to third and it’s good for a couple seconds until it like disengages or free revs then goes back into 3rd, will not shift to 4th or overdrive. Then after a bit it goes into limp mode.
Is this due to the NA TCU? Would like to know y’all opinions. If anyone has a 91 TCU (MD750092) in SoCal lmk
