Toyota 7FGCU32

our lift started leaking at the rear main seal so we replaced that and also the front tranny seal put the motor back in change tranny fluid and filter now the lift when started in neutral will drive forward. shift to forward and will drive in forward.
shift in reverse and the tires stop dead.
bleed any air out checked oil pressure all good checked fusses good
pulled valve body cleaned and valves all free to move checked shifting coils good. any help, idea's to try next. it just don't make any sense at all.

It could be the solenoid valve, with the coil on it, for forward, is stuck on. Can you hear it click when shifting to forward? Does it sound the same as the reverse one? You could swap the forward and reverse solenoids and see if it has the same problem only in reverse. If nothing changes when you swap solenoids and it still wants to go forward, drain the trans fluid, start it and if it still goes forward, sorry to say that the forward trans clutch is stuck and tranny needs to come out but I think that forward solenoid has a problem.
