I've pretty much reached the conclusion that I am going to have to replace the transmission to solve this, but I thought someone might have had a similar issue at some point. Here are the specifics.
Car seems to shift fine through the 4 gears, but on the highway in will engage the lock-up (overdrive) only for a few seconds and only when under a load (if I give it some gas). Once the car speeds up to the point where the load isn't as heavy (not as much torque?) it kicks back out and revs back up. I'm currently cruising at about 4000 RPM at 80MPH. With the ridiculousness of the gas prices, I need all the ecomony I can get (90 mile daily commute).
Car is a 1991 SE, now has 140,000 miles on it (was at 110k when I bought it 18 months ago). Problem has always been present. When I first bought the car, I had to replace the VSS because it failed. I hoped that would cure the transmission, but it didn't. I also threw a new lock-up selenoid on there, without any luck. Could be the TCU, but I didn't see anything burnt in there. Is there a way to road test it?
sorry the the length. Thanks for the help.
