I have a 2001 F250 auto trans.
problem started 2 weeks ago when I noticed it was reving really high- at the time, i thought it was me, when I left of the accelorator, it finally shifted into second. after that, it kept doing. would take off fine but ONLY shift to second when I rev it up and left of the accelorator. rest of the gears shifted fine so it was only an issue at start and stops.
the other day, my daily driver was in the shop for tires and I drove the truck to work. when i left work, it would NOT shift out of first no matter what i did.
now Im stuck. it wont shift out of first. I have first and reverse.
checked all vaccum lines and speed sensors. havent dropped the pan yet but never had any bad smells, shifting noise, grinding or slipping. only have 103k on it so hopefully its not shot.
I have heard possible valve problem or selenoids. any advice?
