I have looked but cannot find a awnser for my problem. I have a 85 4runner 22re automatic. It has always been a little picky about when it shifts through all gears, but after a longer than usual trip this week it will not shift into overdrive. This happened on the way home and I drove it about 15 miles without having a overdrive. It was running on the cool side so I changed the thermostat along with the transmission filter and fluid, guess what still no overdrive. It does shift alot smoother through all other gears but will not go to overdrive. My normal/ power buttons have trouble staying selected, but mostly stay on power or neither lights up. I have no warning lights flashing on the dash other than when the rpm's get too high in any gear before shifting. Any info would be great, I am just about ready to throw in the towel with it.

 

ive got a 87 turbo trans for sale if your interested. idk if it would bolt up.

but on your issue. have you tried changing the shift solenoids? i had a smiliar problem and when i changed out the solenoids. all of my problems were gone.

 

I have not replaced the shift solenoids, I was hoping it would be something a little more simple. If I have to spend around $200 to swap those and it still may not work I think I would do a 5 speed swap and be done with it.

 

Tried pulling the blinking od light codes- mine just stays light- no blinks.

 

i would email this guy (scotty)

hes been prett hepful to me. if you have no codes, then it sounds like a mechanical failure.

 

That would be me............
