Ok..co-worker has a 2000 Impala with the 3.8. She said it has recently (while driving) momentarily turned on all the dash lights (ABS, Batt..etc) and temporarily reset the odometer to zero. After pulling the lump from her throat, and getting off the road, everything went back to normal before she actually got to a stop.
Car ran fine and never skipped a beat. All happend within a 5-10 second span.
Car runs fine now, but she wants to know if there has been some code tripped or some other computer glitch that may cause problems down the road.
I'll have the car at the house tomorrow to service the tranny. Not that that has anything to do with the above problem, but I can look at some things while it is here.
Anyone in GM cyberland got an idea on this???
