Good Afternoon . If the transmission wont move forward or reverse and its full of fluid , then it will have to come out to be repaired . Unfortunately nothing external can cause that .

It'll shift into reverse but won't engage like the torque c onverter is filled
Automotive Expert
Is the fluid full ?
Automotive Expert
If the fluid is full and it will move one way and not the other way then it has to be internal , if it didn't move at all if could be the torque converter or front pump
Automotive Expert
Let me know if you have any more questions about this

When to replace clutch?
Your description sounds like normal clutch wear. The clutch disc has friction material similar to brake pads. When that material wears, the self-adjuster makes sure it remains the same distance from the flywheel and pressure plate. Once the clutch disc...
