Can anyone help with an answer. After a twenty minute highway drive, when slowing for off ramp the transmission makes a grinding sound and just before stopping it clunks down into first gear. I have had it back to the dealer and they have not been able to repair it because they cannot get the truck to repeat the noise. Does anyone have any sugestions as to what might be causing the problem.
Thanks

 

are you turning the overdrive off as your slowing down or anything that could confuse the transmission into doing somthing stupid? lol

 

When I slow down from highway speed the transmisssion grinds then clunks
down into low just before stopping. Overdrive button is not touched.
Any ideas.
Thanks
