driving around town the light stays off, but if im on the highway for a while the light will turn on. my 8.8 3.55 LS clutches are going to hell. my question is can the transmission sense the clutches going bad? because this light only turned on after i changed an axle seal and realized that half of my clutches were gone in my diff because i was turning it all around trying to figure out where these metal tabs came from in my fluid.
you should have dumped your tranny shop...not the truck.....
In my town that shop was the best, they have been around for 30 years. It was them, an Ammco and some other franchise, the kicker was I had an extended warranty that expired 1000K miles before the light began flashing.
It turned out ok, cause if I still had it I would not have my current ride (which is 2 rides later than the expy shown below).
same config as mine, you may have the same issue i had especially if theres no symptoms and the trans acts fine. i never got a straight answer on why the speedo drive gear swells, but it happened to me several times until i put some epoxy on the shaft and the drive gear.
