Try shifting into third or second before shifting into reverse. If that doesn't help and you're running a hydraulic clutch.. I'd trying bleeding it..

Well, here is the latest in the transmission saga.

The grinding in reverse steadily has gotten worse (no matter how many forward gears you engage before shifting into reverse or how long you wait) and putting the trans in any forward gear at a stop requires real muscle (no grinding, just a firm hard push to engage). Trans shifts beautifully either up or down once moving. It also shifts effortlessly when the engine is off and the clutch is disengaged.

The car is at a different shop having the trans removed once again.

I am going to use a pilot bearing this time instead of a bushing and see if there is any improvement.

Will let you know after the parts are removed if there is any obvious signs of wear.

Jim,

Can I assume if while leaning on the shifter and you turn the engine off, the box drops into gear as the engine stops?

If that is the case, you most likely have a dragging clutch or a dragging spigot bearing.

Either way the input shaft is not coming to rest as easily as it should.

I agree.... the clutch is most likely dragging. I had the same issue.

Once I put a new Wilwood slave cylinder on the clutch arm and made adjustments to the pedal (to get full travel, all my issues went away). My prior clutch arm movement was about 5/8". I now have over 1" arm travel.

Measure your clutch arm travel from rest to full clutch pedal depression.
