Manual Transmission Noise
I just picked up a 1991 2wd truck with 124k on the clock (I suspect that it has more on it though), a 22-RE engine and a 5 speed manual transmission. It is a basic model with no power steering, or power anything for that matter!
When i bought it, it had a bad fan belt squeal and barely made it home. I went ahead and went whole hog, replacing the radiator (had a small leak), water pump, fan clutch, thermostat, hoses, and fan belt and now she's doing much better.
Problem is that after the fan belt noise was taken care of, I noticed a bit of noise coming from the transmission. It is a "rotating" noise that goes away when the clutch is pushed in. This happens if the truck is moving or at a standstill. In addition to this, it seems to make a bit of a whining noise in 1st- hard to tell though.
I checked the tranny oil and it was a little low (under a quart) so I topped it off. I would have replaced it, but don't have the correct socket for the drain plug.
What do you guys think? It pulls and shifts just fine through all gears, just makes a bit of noise. No "clunky" or "chunky" metal noises.
The clutch grabs close to the floor and supposedly was replaced not to long ago... the fact that it doesn't happen when the clutch is depressed makes me think that it is the tranny. I don't think that it could be anything from the transmission back b/c it makes the noise at a standstill.
I am all ears (eyes) if anyone has suggestions.
