Reverse grinding, please confirm the cause Options

IIRC when reverse grinds, it is probably caused by the clutch cable, right?

Stretching a bit or the nuts loosened up? And of course the dreaded tube.... but lets not go there yet.

Have I remembered correctly?

Grinding in reverse happens because either the car is still rolling or the mainshaft is still turning. Mainshaft turning could be due to several things including bad clutch adjustment for one mentioned reasons, a warped clutch disc, pilot bearing seizing or not waiting for thin gear oil to slow the mainshaft before trying to engage reverse.

All true. Check you're adjustment first, then check that the clutch pedal travel limiter hasn't slipped down limiting the travel. My car needed the clutch release arm shimmed out due to the arm hitting the case. You have to pull the gearbox but it is an easy fix. Hope it isn't the clutch tube but I think that is not the norm.

Thanks guys. That gives me a few more things to check this week.

Clutch tube is easy to check, I have checked it many times. The PO jack-legged a repair with a U-bolt and a 1/4" thick small plate welded to the outer firewall where the tube exits.... plus he cut several holes in the top of the tunnel for my benefit. (IMG:style_emoticons/default/blink.gif)

I have been seeing a bit more oil on my cardboard under the car. I might be seeing Tranny oil. So maybe the seal is a problem. Tranny oil level check is high on the list.

This grinding has really just popped up. It started about 2 weeks ago, maybe once a day. Then yesterday, it seemed to sound off on about every other shift to reverse.

Not really a grind, but a click-click-click... (IMG:style_emoticons/default/headbang.gif) the comment about the gearset not slowing down makes sense with the sound. The clicks are close together at first, then slow as the gear is found.

It has not been too long that Dr Evil has been thru this box, maybe 20K miles. So I doubt it would synchos.
