My 5 speed Jeep does the same thing...with the clutch pushed in and everything.  Could it be bad gear synchronizers?  I'd like to know why it does this as well...

T5 transmissions (at least earlier ones) did not have a reverse synchronizer.  They used a sliding idler gear.


If the input shaft is still spinning from inertia or momentum or anything, it could let out a quick grinding sound.
Otherwise, make sure that the clutch is getting fully disengaged when the pedal is depressed.

Try putting it into first, then into reverse when you stop, and it almost always stops the grinding.
Don't let up on the clutch though.. Stop.. hold it down.. put it in first..then without taking your foot off the clutch, just put it into reverse.

If it still grinds, you have an adjustment problem, or internal damage.

I forgot about that old trick.  It usually works though.

I've had to do that touch-another-gear-first trick for quite a few years in my 80 AMX. The clutch doesn't fully release so touching the sychro in a forward gear stops the tranny for a sec so you can slip it into reverse. This will eventually wear out the sychros so I will have to get it fixed.

My grandfather was a transmission mechanic, so I learned some neat tricks.

We used to have to shift to second before shifting into first at a stop when many transmission did not have first gear syncrhos.  Those were the days.

Why did we all think "manual" ?

Then I guess something gear related... The AT fluid's color and smell is not enough to diagnose a tranny problem, though. Maybe it's just been sitting there too long. I'd open the pan and check for metal debris or something like that. If you don't find any, replace the filter and try fresh fluid.

Oh, really ? I guess that's why I need BOTH rear bumper corner caps now. Doh !
