89 Supra, auto tranny, no kickdown, no power mode
Help Please. My 89 N/A Supra with auto transmission recently quit
going into power mode, like suddenly, not gradually. Also, it won't
go into passing gear even with pedal to the floor, with or without
power selector on. I read that this might be a problem with a lockup
solonoid? Anybody know what could be causing this? I have changed
transmission fluid and added Lucas additive hoping for a miracle fix, but it is still not fixed.
Also, code 42 has been on for a long time for #1 speed sensor. I
didn't figure this was the cause of my trouble because the error
code has been there for a long time before power mode and passing
gear quit working. Transmission still shifts into all gears fine,
just will not power shift when I need it to now. Is this torque convertor trouble? When this first happened, I was driving in standard mode when the transmission suddenly sounded like it had been knocked into neutral for a few seconds, then back to normal, except will not kick down for passing or more power. Your help appreciated!
