Why won't it engage any forward or reverse gears?
auto or stick trans, we find out its an AUTOmatic.
this trans is most likely a pure hydramatic.
and no TCM tranny brains then.
check levels next. (by the book dont guess)
check the shift cable, for proper movement. in all gears.
"selections, they are no gears" the automatic shifts via clutch packs not gears. like stick does.
move the shift lever and be sure the transmission end of the cable moves 1 for 1 same; that is moves to all transmission shift positions. (at trans itself)
if not the cable is bad or came loose.
inspections are first never transmission swaps, blind (on a whim);
the FSM book covers all this."chapter, on car service" all cars made have this chapter.. an amazing fact.
next, is get a new filter in the trans.
if clogged, the pump can not suck AFT. (shunted input)
so line pressure drops, and it cant shift.
no need to do the stall tests as it fails 100%
next is line pressure, tests. if that fails,
it needs a rebuilt trans.
but dont take my word , read the book.
or ask your tech to do the tests, he knows, how...
