July 12/2006...

Update: I've noticed one mechanical issue with the 3.52.

Sometimes when engine-off coasting, I can't easily get back into gear to do my next clutch start. Meaning: I'm coasting with the engine off, depress the clutch and try to select a gear. And... no go - the shifter resists slotting into gear.

If I force the shifter under these circumstances, I crunch into the gear I'm trying to get. I've tried double clutching, and tried to select other gears than the one I want, but it doesn't seem to work.

The transmission itself seems to shift nicely when the engine's running though. I don't think it's synchro related.

One other thing I noticed that may be related to this: yesterday I popped the car into neutral to roll out of a parking spot (hadn't yet started the engine), and it wouldn't really roll easily, like something was hanging up a little bit. I pressed and released the clutch once, and that fixed it - something seemed to unhitch and the car rolled normally.

Mechanical gurus: all this seems to suggest what? That the clutch is not fully releasing sometimes? Is that the clutch release bearing (which I know nothing about... I'm just throwing that term out there)?

It's not a massive problem, as it only happens once in a while.

Edit: the "new" tranny also has a very quiet mechanical "whine" when the car is stopped (engine running), the shifter in neutral, and the clutch pedal released. Don't remember the original tranny making that sound. Adding this in case it's related.
