Okay, so I drove it for two days with no AT light, then yesterday (after a 20 minute drive at highway speeds) it came on after restarting the car to check. Checked the codes... 24 (Duty C), with no 32 (VSS1). Just drove in tight circles, no torque bind. Shifting feels really good after all of this new ATF I've been putting in. I don't really get it... If the duty c were failing, I would get torque bind and the FWD fuse would not work, right? I was really hoping it was a bad VSS that was messing up everything like you said, fairtax4me, but it doesn't look like that is the case. It appears that the problem occurs when driving at highway speeds.
Something strange that I've noticed is that the engine temp gauge always reads warm (normal operating temp), even when starting on cold mornings. Weird. Wiring problem?
Coming from my 2002 VW, where sensors go crazy all the time and signal the CEL, I'm surprised that I'm not getting any CEL codes for things like this. Normal?
