Hello, so here I find myself trying to figure out what's wrong with my 2009 M2 Freightliner's Allison Transmission.
It drives good most of the time, but suddenly the tranny light turns on and it jumps to 3rd or 4th gear, if I restart the engine it'll reset and run fine.
Occasionally I'll have to wait a while for it "cool" off and reset, for the truck to run again.
It has 420k miles, recent tranny flush and replaced all sensors.
Please, any ideas?
Thinks in advance for any advice offered.
