2001 1.9tdi Gearbox Whine In 5th

[Lecky Guy]

Hope someone can help, when decelerating in 5th there is a whine from the gearbox, pushing the clutch pedal down makes the noise disappear, it doesn't do it in any other gear.

 

This is a reconditioned gearbox fitted 2 years ago & has only done 10k though the car has done 145k

 

Clutch was changed at the same time & feels good, no slip/ strange smells etc.

 

Gearbox works perfectly in all 6 gears & reverse, doesn't drop out of gear, changes gear smoothly - just this weird whining!

 

Thanks In Advance

Hi if the noise goes when the clutch is pressed down it would normally suggest a bearing in the box is noisy associated with 5th gear. Depressing the clutch pdal means you have removed the loading from torque from the engine hence the noise stops. If it was a wheel bearing I would expct it to do it at a certain road speed or when loading the bearing when cournering.

A good start point would be to check the oil level on the gearbox incase it's low but other wise I would say it's a fault witin the box.

Thanks Dave, dont laugh but how do I check it, did some searching on the forum & it looks like there is no level check as such but just to fill till it comes out of the hole, is that correct?

That's correct, remove fill plug and fill till oil is level with bottom of hole. Like you say if you over fill it a little just wait till the oil stops running out then put the plug back in and wipe up the mess!

Ok removed filler plug & used a bent piece of wire to probe around, it came out dry!!

Think i'll do a complete drain & refill but firstly Ford want £17 a litre!!!!!! & they say I need 3 litres

So my questions are:

: Is there a suitable (cheaper) replacement, tried Wilco but they say I have to get it from Ford as it's "special"

: How much do I need for a complete refill - is 3 litres enough

 

Thanks

Hi try the local motor factors for the oil, you will probably not use all of the 3 litres as they usually quote fill quantities for a dry box.

If there is very little oil in the gearbox I would start looking for the leak as you could have an oil seal leaking dropping the level.

As far as draining and refilling with fresh check what drains out of the box to see if there are any metal fillings in it.
