Just bought a 08 f550 4x4 dirt cheap with supposedly a bad tranny. Runs through all gears forward but, cannot hold reverse (Not enough piston pressure on clutch pack?)checked line pressure on hot tranny
P=50. 100=stall
R=45. 90=stall
N same as park
D=80. 120=stall
3=80. 120
2=80. 120
1=60. 120
Is there a way to check front pump output?
Could it be a stuck pc a solenoid?
Fluid looks clean
It's not throwing any tranny codes
I know pressures should be much higher just trying to get some advice so I don't throw parts at this thing
