Quite probably it is on the electronics side [not necessarily]. Anyways omputer controls its mechanics with some four solenoids. One computer used input is TPS, if it gives out whatever, results through computer will be none better.

^ That's very helpful. :screwy: What a friggin' genius.

I had exact same problem. It took me about 3 month to figure it out with a voltmeter...
Anyways, check your revolution sensor(Vehicle Speed Sensor) that is attached on the driver side of the transmission extension housing.
