I was driving the truck last yrs no problems really after I got it out of storage the temp gauge in the truck doesn't come to normal temp.. an for some reason it ain't shifting probably.. seams like the small shift after 45 don't engage
My car has 165000 miles.
My car has an automatic transmission.
It sounds like the coolant thermostat is stuck open and allowing the coolant to flow freely through the system. This will keep the engine temperature well below operating temperatures. As for the transmission, I would check the fluid level and condition and make sure both are good. If so, you may have internal transmission failure.
