Ok this truck is starting to kill me!!
Just got the truck and took it to the shop to get all the fluids changed. They called me today and said that after they changed the tranny fluid it will not shift out of 1st gear. They are suppose to be trouble shooting it tomorrow. Seemed fine before they changed the fluid. Did they mess something up or is this going to be something easy for them to fix? I sure hope I am not looking at a new tranny

It’s a 01 F350 SRW with 160k on it.
