So my 95 d1 has a whine from the tranny/transfer case area. Currently am running Redline MTL in the tranny and Redline shockproof in the transfer. Curious if the whine could be from the output shaft bearing or its syncro's/tranny related. Does the bearing whine when going bad?

I've owned the car for a year and it has made this noise since I've owned it.

 

I'd take it to someone who knows R380's and have them test drive it. It's really hard to diagnose a "whine" on a forum.
Land Rover manual gearboxes can be noisy. Mismatched gear teeth can cause a whine as can failing bearings.

 

Understood-unfortunately I'm 2 1/2 hours from even a dealer. Folks in my area know pick-em up trucks and not 'foreign cars'. Guess I'm fishing to find out if anyone has ever solved a whine by replacing the bearings rather than pulling a tranny.

I realize that transmisions can have lots of noises and run forever-however if I could quiet it down by changing a bearing I might consider it.

 

Is it a whine on the gas or off? Meaning does it get louder on decel or when you're on accel? Or maybe its constant...

 

It increases with the acceleration, pretty much constantly there (all 5 gears), doesn't get significantly louder, but speeds up as the car does.

 

If you coast down a hill and turn the engine off and trans in neutral does it still do it?

 

I wouldn't suggest a dealer for that noise, they are not trained in overhauling 5 speeds and will just charge you a bunch and tell you that a new tranny is in order.

 

On top of this, with the engine off and coasting, does it do it with the clutch depressed as well?

 

Either way it quits, clutch in or out when coasting. In fact, the whine quits when shifting between gears and resumes when I let the clutch out in the new gear.

Hmm, I think I see where you guys are going. Since my driveshafts are still turning when I coast, it won't be an output shaft bearing.

I agree Mike. My wife threatens to take my ashes by the dealer so I'll have been there once.

 

I dont see why these other guys wont look at it, hell man, a tranny is a tranny.
If you took it out of the truck and took it to them they would not know the difference.
