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?
