So I got a new clutch and flywheel out. Everything worked fine for about 20 miles on it, then i shifted hard into 5th and nothing, tried 6th still nothing. It's like it's in nuetral, it won't even stall out at a complete stop. I know we don't have linkage or cables for our trannys, so what else could it be? It goes into gear when I'm parked and will move the car ad long as I start from a stop, but not while I'm driving. Any ideas?

 

Check the alignment of the shifter plate. This is the first thing removed usually when doing a manual transmission. The shifter plate has a shallow dowel and if it's not aligned the right most gears are fussy.

This can be accessed by lifting up your shift boot trim. Let me know how it goes.
