Small update here.

After excellent performance, all of a sudden I am experiencing gear grind in at least 1st, 2nd and 3rd. I turned around and went home before I could find out if it’s also in 4th and 5th.

I’m going to wager that it is either low trans fluid (synchros are not working?) or low clutch fluid.

It’s weird ‘cause the grinding seems to be happening while the gear is fully engaged and prior to releasing the clutch pedal.

More testing to come.

Hm. If it had been low clutch fluid, I would imagine it would be the traditional symptoms of 1st and reverse that are difficult to engage.

My guess... I’m losing tranny fluid out of rear seal

Shift lever feels a little notchy too.

Hm. Must be fluid. But 23:22 here. Time to zzz

The growling / grinding doesn’t occur as I’m trying to select a gear, but rather as the gear is already selected and before I release the clutch pedal.

WAG
assuming correct fluid amount & type
TO bearing
input shaft bearing

I’m betting on WAG one.

I used Dexron III instead of II. But I understand III is retro compatible with II. I doubt that’s it.

On the other hand I discovered this:

...

It looks like it is leaking out of rear seal.

I pulled the upper plug and did the finger-dipstick test and found it was way low. Hopefully no damage.

I’ll have to check that vent tube. Maybe it’s kinked.

The question now is that rubber boot. I know the seal is under it. I’d rather not damage the boot as I replace the seal.

Do ensure both tailshaft housing Bushing and outer Surface of Yoke are Not worn; if either damaged or worn, No seal can seal.

Well, I was missing about 0.4 quart. IIRC full is 2.5 quarts.

The noise came back... but then went away. All this makes me nervous.

Having thought a lot about it, I suppose one other option is possible: debris lodged between the clutch disc and the flywheel or pressure plate. (I forgot to put on the inspection cover.) The clutch disc is brand new. The grooves are super crisp.

I doesn’t sound like the throwout bearing. That seems to operate like new most of the time.

The noise was sometimes a graveling sound at others it sounded like a high speed ticking, like a card against the spinning teeth of a crown gear.

If dirt got in there, if it rubbed against the edge of the clutch disc it would make a grinding sound. If it caught the side... with the groves of the disc, it would make more of a gear clashing sound.

That would explain why the sound would be with clutch fully depressed and when coasting in (2nd or 3rd) gear. That’s when the clutch disc is spinning because in gear. The disk is grinding or ‘slapping’ against debris in the pressure plate spinning at a different speed.

Any thoughts ?
