Check resistance with an ohm meter of the coil for the fwd solenoid....pneumatic models 4-7 ohm. Cushion model 10-15 ohm.... Does this have the large single solenoid on top of the transmission or is it like the nissan trucks with the two solenoids on the right side of the trans,top? If resistance reads good is more likely the switch in the control handle......reverse works ok??? Code listed in your heading is F-85 is this what your getting for your code?
