Fifth gear no go?

[Jehu]

My Son tells me when he tried to shift his e34 525 5 sp into fifth there was "a lot of play" and it wouldn't stay in... what is the F'ing problem ? Worn synchro? New tranny or rebuild for short money?

Probably the shift linkages

Probably the shift linkages


Those inside the bell housing or something that can be fixed from underneath?

Have a look at this:

All of this is accessible from under the car, though tight and you really have to know what you're doing...

You can remove nut 5, flip over part 3 and slide it out - it's a weird affair - you have to push up the lever end and then the other end is a big pin that slides out.

pop lock 16/17 out and you can lift the whole shifter assy out under the car for inspection.

Beware - this job requires that you do it blind as your hands will be in the spaces that you can usually see through. If it's not been disturbed for a long time you may find part 3 *very* reluctant to come out with the box still in the car!

I should have a photo of the assy somewhere but photobucket is currently offline.

I'd think it quite hard for something to fail inside the gearbox that would give it a lot of play - you've probably got a linkage on the blink somewhere. Something to inspect - pull the gearknob/gaiter off, then reach in and pull the boot off the bottom of the shifter and make sure the plastic ball hasnt collapsed from some 'speed shifting'...
