a340f transmission question

[old4runner]

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?

 

[old4runner]

Checked..

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?

 

[old4runner]

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.
