I have been searching for the last 3 days to find some help about my problem. I found some really cool stuff but nothing that helps. Here is the problem.
1990 7mgte auto. Stock. There are no code for the trans. Normal driving everything is fine, but at WOT it won't shift out of 1st and hits the rev limiter. I have done the check out of the system TPS-ok, in the troubleshooting guide it points to the ECT ECU or the trans is bad, but I can't find anything else to narrow the problem down. When checking the ECT ECU some voltages are low but the book doesn't say what to do. The trans was rebuilt about 20k miles ago. Anybody got any ideas?
