ImUrOBGYN Posted April 14, 2011 Report Share Posted April 14, 2011 89 Supra auto tranny A340e Tranny was working great. Pulled motor to rebuild. Reinserted motor. Test drive after everything is done and notice a tranny issue. Basically, the transmission ignores L and 2, for the most part. Everything works fine; P, R, N, D and O/D. If you put it into L or 2, it may drop down into them a little sooner than if you had it in D, but otherwise, it upshifts like it's in D. It used to hold L/1st, well, for as long as you had it there regardless of rpm or speed. Same with 2nd. Suddenly, it doesn't. The tranny is throwing no codes. I disconnected my tranny ecu and it shifts manually with no problems including holding each gear so it shouldn't be a mechanical problem. Im wondering if it's a solenoid problem. There are 3 solenoids. No. 1, No. 2, and a lock-up solenoid. I cannot currently get under there to check any of them, however. Any ideas anyone?
