gearbox

Does anyone know why I have grinding and high pitch noises in 5th gear. juddering when pulling away in 1st and 2nd gear sometimes. wondering if anyone could help diagnose it problem cheers

its a m reg 90 if that helps?

Juddering is usually the clutch drive plate glazed. When you say grinding do you mean the gears aren't engaging properly if you do this is usually the clutch on its way out or the clutch hydraulics. dunno about the high pitched noises. But at a guess your clutch is on it's way out.

well it goes in gear ok but just hums when in gear?

Wot no drive?

it oes drive but when in 5th gear the gearbox makes a high pitched whine

Wots the oil level like?

sorry to jump in, but glazed clutch? wot is that exactely, i sometimes get juddering in 1st and reverse
thanks

Dunno exactly cos I've never suffered from it. But apparently if the clutch has been ridden or slipped excessively the steel plates can become glazed and this causes clutch judder.

that may make sense, gave it a hard time yesterday off roading with swporc

Someone else should be able to shed a bit more light praps.

its yer clutch plate that gets a glass like surface to it from overheating. causing judder cos you get slip then grip then slip etc. you can fix it by going over it wiff a sander and some medium sandpaper, but why bother cos if you've got it out you might as well replace it

Geez ..... FIRSt do as the man says and check the gearbox oil levels.
FILL them as specified.

Using the clutch in slipping mode makes the linings very hot ... Like VERY VERY hot ..... like smoke and flames if you try really hard.

After the FIRST time clutch linings get that hot they are jiggered for good, AND the rubbing surfaces of the flywheel and pressure plate may be damaged.

The slightly soft lining gets baked hard like a mixture of cement and glass, all shiny, and the trrouble then it it either grips or it doesn't. It becomes difficult to set off smoothly because the clutch just grabs all of a sudden often with a judder.

Slob will explain the cure ....

cheers.
that solves that

Just live with it, and it may get better as you get used to it!

BUT, be aware that utter failure of the linings is possible if you really cooked them.

The two linings can get so hard and brittle they just break up and drop out in bits, and you get into heaps of trouble ..Schedule a clutch job if you know you fried it.

the oil levels are fine in the gearbox and engine. could be the clutch with the crunching nosie but the whineing is really annoying me!!!
