My 89 acclaim transmission seemed to be grinden
when switchen from first to second n second to
first when down shiften it seemed to have
problems goin up hills benn shiften by hand to
avoid damage but no it won't go into no drive gears
but reverse works fine would that be my torque
converter or maybe my filter?
Sounds like the transmission is toast. Only way to fix is replace. But since your car is an old 89 Acclaim, not worth anything more than scrap value, I will say to keep it running as long as you can before you purchase another vehicle.
