Hi guys,

I have searched everything I can think of and I'm hoping someone on here has had a similar experience.

I have a 1997 4runner with 289,000 miles. A few weeks ago, my transmission just refused to shift correctly and I'm not getting any codes. It will shift normally from 1st to second one time. After that I would have to rev it up to about 4500 rpms and back of the throttle completely to get it to shift. I replaced all three solenoids, but no change. I even replaced the computer, but no change. So, I got a used transmission and threw it in there. Now it is doing the exact same thing.

I guess my next stop is to start tracing the wiring harness. Does anybody have any experience with something similar?

How about your kick down cable adjustment?

Just getting back around to this. I checked the kick down cable.

I also unplugged the wiring harness for the solenoids and I can shift through the gears with the shifter. I think my next check is the neutral safety switch.

While throwing in the new transmission, did you replace the torque converter as well?

yes, new torque converter.

Just checked the voltage on TT and E1 which I think is supposed to be signal from TPS, but got 0 volts. I'm not convinced I have the right terminals, because I'm not sure if I have the right manual for the 1997.

It was the TPS. Replaced and the old 4runner is sbifting great. It shorted out at about 75% throttle.
