Hi.
I have been having a strange shifting issue with my 1994 4runner v6 4wd automatic.

It had a leaky valve cover so a friend and I decided to replace it. We removed the upper intake manifold, throttle body and some hoses to get down there to replace the gasket on the valve cover. We replaced the gasket on the intake manifold as well then we put everything back and i drove it home.

The next day I noticed it jerked kinda hard when shifting in to reverse from park and that the idle was a little high. It also jerked a little when shifting from 1st to 2nd. Changed a few old hoses since we thought the high idle was causing it and it seemed to improve a bit and we left it alone.

I tried to drive it on the interstate and it started ok but once it hit about 50-60 it was struggling to keep up. Sometimes id have the pedal all the way down and it would start slowing down and revving a little high. After a few more miles of that the A/T oil temp light came on and we had to pull over to let it cool down. After that the shifting was much harder and it jerked more. Drove it again this morning and it was shifting much harder and jerking out of 1st hard but shifting normally after 2nd until i had to stop and shift out of 1st again. At one point it jerked hard and the check engine light came on for a split second. Please help! Thanks again in advance

Check the kick down cable from the throttle body to your tranny.
