I have a 90 4runner with 3.0 engine, and what my problem is is that when i put it in reverse if i just let off the brake and dont give it no gas it reverses fine, but when i give it gas it wants to slip,and when i let off the gas it will continue to go in reverse until i put my foot on the break of course. The fluid looks full and i have only had the vehicle for about a week, it drives fine in drive seems to shift fine.This is the first toyota i have owned so im not sure exactly how they run when all is well.

 

here is a link for the fsm in there is trans stuff, my guess is bad clutchs for reverse or relay not clicking in,

I looked at the link and omg, where would i find that relay and is there a way to test them.

 

also do you think i would be wasting my time by doing a fluid and filter change?

 

not sure what relay u are talking about but it might be inside the trans and to get to that u would have to drop the pan, all fluid and filter, and replace them.

 

You mentioned in your first post relay not clicking in, thats the relay im talking about.

 

oops meant solenoid that locks it in reverse and those are inside the trans. when u looked at the link did u see the area that covers the different trans? what trans do u have?

 

also one thing pull the park neutral switch and see if u have continuity threw C and RL on the switch on the trans in reverse. see link.
