Wondering if anyone had an answer to my problem with my 2001 dodge ram (badlander), being that after about ten minutes of driving, my overdrive turns off and I can only drive at about 45-50 mph, if I go faster my transmission temperature light comes on and I have to stop and let it cool down?

Does it have enough transmission oil in it?

Yeah it does

Same problem to my RAM 98, I had replaced twice and also the O/D OFF lights goes on. The thing you have to do is to replace the TORQUE CONVERTER.
