Well, back to my original question. Will a bad lockup solenoid cause the shifting problems? It's not slipping, just shifting very late at about 4500 rpm.
Fluid looked ok. Nothing unusual in the pan. New fluid, new filter and topped off. Acting the same as before, no improvement. It's not slipping, just not shifting as it should.
Ok, so I have a 1990 T4R 4x4 that is not shifting properly. It works in 1st and reverse. It won't shift into 2nd until around 4500 RPM. I bought the 3 shift solenoids and was able to install 2 of the 3. I installed the 2 shift solenoids but was not able to install the lockup solenoid because...
