HELP? Where are the fuse & resistor located on my 89 4Runner for the ECT (TCU)
So, this is my 1st 4Runner. 1989, 3.0/Auto. It has the shifting problem, and I have dug up AW4 troubleshooting tech help off the net. It has a brand new TPS from the person before I bought it, and a fresh trans flush & filter. I am shifting it manually currently. I disconnected the ECT (TCU) & tested the D16 pin (+12VDC w/key on/engine off- good) and then C10 pin (no voltage w/brake on or off - FAIL). According to info I have, this points to the resistor and of the fuse/wiring upstream toward the ign.
I however, cannot find an inline fuse, nor a resistor. And I do not know where/what to look for.
Can anyone please help point me in a direction??
THANX!

The resisters you are talking about are probably the solenoids to control shifting. Here is a link to a site that has an A340 auto trans factory service manual for download. http://www.ncttora.com/fsm/index.html
This should be able to guide you through the troubleshooting. Good luck and hope you find the problem.
