Hello, having some problems with transmission..
Truck shifts fine, but notices od is starting to slip and the issue that bothers me is I’m having to hit od bottom to get it out of od or mat it to the floor just to get it out of it and I don’t like doing that.. is that normal? Is there a fix for that or is it time to have transmission rebuilt ? Truck has 140,000 miles and fluid isn’t burnt smelling just slightly discolored.. I’m not sure if it was ever changed. Any help would be appreciated..

Ok I’ll try that, just hope it don’t slip more after I change it
