Ever since I've had my SS (it's a 6-speed) there's been this small issue where if I put the car in reverse (to reverse out of the garage for example), every so often I'll get a grinding noise after releasing the clutch to the friction zone. You can hear the gears grinding in the gearbox (it's not too loud though), and the car will not start to roll. Once I put the shifter back into neutral, then shift right back to reverse, I'll have no problems.

What is the reason behind this?

is it the trans or clutch chatter? what clutch do you have?

or possibly a bad synchro

when the shift fork pushes against the syncro there can be a bind when trying to engage the selected gear. try going fifth to reverse or fourth to reverse and see if that helps. also whe was the last time the trans was serviced.

I hate to tell you this but that is normal for ALL T56's. All 6 gears have friction material on the blocking rings but on reverse, it uses bronze blocking ring that really doesn't have any friction material to slow down the reverse gear enough. Try going into 5th before shifting into reverse, that should slow down the moving parts inside enough to not grind.

Just so you know, I replace about 98% of the reverse gears (the little engagement gears are rounded off) on the rebuild I come across.

Thanks!

I actually don't mind it too much, and am glad it's not specifically my car that needs service.

mine does that too man. i just hold it in reverse while i let out the clutch and it clicks in. or you can go to 5th first thats prob the better thing..
