Tranny locked in 5th gear

After my accident the transmission has been stuck in 5th gear. I can only move the shifter into the 5 and R gates and in neutral will not go to the left from where 5 and R are. Even when teh shifter is in reverse 5th gear is still engaged. Is there a way to fix this or in something internally broken and I need to replace the tranny? Thanks in advance for any help.

Only way to tell for sure is to pull it apart. FSM has a full manual tranny rebuild section. As cheap as trannys are, might be simpler to buy one and save your's for spare parts.

This is not uncommon on a Sa trans. There is a thread about this. I read it once and it is not a major job since it does not involve the removing of gears or bearings.

We always hope that it's a messed up shifting link on top of the gearbox, and once every hundred years it is! I actually freed a stuck gearbox once by working it, driving in the one gear that would work, abruptly accelerating/decelerating, applying sharp blows to the lever, etc. It finally came free and worked fine for at least 50k miles.

But usually it's inside the box and if it took place over time it's accompanied by a history of bearing noise usually ending in a no-go. If it happens suddenly it may be a jammed fork or syncronizer.

I was involved in a collision where I hit someone making a u-turn in front of me. When they pulled out I jumped on the brakes but dont think I depressed the clutch and the tranny was in 5th. After the collision I was only able to move the shifter out of fifth and into reverse, but no other gear. Even when the shifter is not in 5th the gear is still engaged.

This does happen frequently in accidents. Can the appropriate thread be promoted to the FAQ or archive or whatever so it's easier to find?
