1994 ford 150 4x4

WE HAVE A 1994 FORD F150 4X4 THAT HAS A PROBLEM THAT NO ONE CAN SEEM TO FIGUIRE OUT. AFTER THE TRUCK IS DRIVEN 2 OR MORE HOURS STRAIGHT, IT STARTS TO DOWNSHIFT AND WE DON’T KNOW WHY. IS IT A TRANSMISSION PROBLEM OR IS IT A SENSOR? ANY IDEAS?

I am truly sorry I don’t have any ideas on your car problem, but please don’t use ALL CAPS. They are hard for most people to read so many people will just pass by and not read them. Also try to be careful about double posting. It is easy to do.

I bet on the transmission problem.

I was trying to get help with fixing my truck, not advice on how to type my question
