Reverse gear engaged while in neutral
 

:bs:

5th gear went out just before this had happened

The shifter is free to go in all gears with the clutch pedal in. When I release the pedal gears 1-4 grind and the car goes nowhere, while neutral and 5th go in reverse

For what it's worth the clutch has been going out lately, but I doubt that has anything to do with it considering the car still moves

I'm sure I need a rebuild. Any tips or ideas before I submit to a mechanic?

replace the trans
