Ok, I installed the new TPS after cleaning the ground at the passenger side block and the one on the head on the drivers side back corner. Adjusted the TPS to .82 volts between the C and B wires on the ECU pigtail of the TPS even though I originally thought that it was suppose to be set while reading the output voltage of the TCU pigtail but took a chance on doing it the other way when I figured out that the TCU pigtail doesn't have a C pin. Took it out for a test drive. Results, trans shifts pretty good now through all gears at about 2500 to 3000 RPMs at WOT. Idle is a too low for my liking though. About 450 RPMs at Idle in park and 350 at idle in drive. Oh, and it died on me once while pulling into a parking lot but started back up fine. Rechecked the TPS adjustment. Still .82 volts. DID NOT install a ground wire from the TPS to the negative post on the battery though. I wasn't sure whether to splice it in on the ECU or TCU pigtail or both. Or whether to splice it in on the TPS side of either connector or on the harness side of the connector. I really need to learn more about using the multimeter I bought today also. I really want to be able to check the resistance in my grounds. Over all, I think I am back to where I was before the trans stopped shifting automatically. Any thoughts on the low idle or if I did anything wrong?
