Transmission not so good
I went out to the woods this weekend and when I left my truck barley shifts from first to second and it does it really soft. It holds first gear. I never got it hotter than 190 the hold time. I was running not to hard but the sand was soft. I guess its time for transmission. But 3rd and 4th gear are just fine and the torque converter seems fine cause it locks up normal. Just want some input on if its an easy fix or its time to pay up for a new one. It does have 164,000 miles on it.
