My transmission is shifting roughly on the upshift, and does not
downshift when slowing down. On hills I have to floorboard it to get
it to downshift.
I borrowed a friends reader/scanner and got the following codes:
P17757 Governor pressure not equal to target at 15 - 20 psi
P1740 TCC or O/D Soleniod Performance
How serious are these problems, do they represent the need for a major
overhaul or rebuild, or just repair and/or adjustment?
I am trying to determine if I can afford to have a shop repair it at
this time or if I can safely delay repairs a few thousand miles.
