I had the reverse grinding problem for awhile, but only when hot. It could be as simple as your fluid boiling if the line runs near the headers/sidepipes. I went to a higher temp fluid and better insulation, which solved the problem.

It could be the slave adjustment if you're having trouble shifting into other gears on occasion too. Do you have an external slave (which is adjustable), or a hydraulic throwout inside the bellhousing? If you have no other shifting problems in any other gear, I'd look at the lines first.

You need to look underneath the car first before anyone can help. It's not an SPF or toploader question, but depends entirely upon what type clutch set-up was installed, which is unrelated to car or trannie type.

EDITED Why is this in a toploader forum?
