Autobox trouble?

(1/2) > >>

SteveGoodz:
Howdy folks. It's official ... I dislike my D1  :cry:

The latest is a knocking noise that appears to be coming from the autobox but as you can't always hear it the diagnosis might be wrong  :undecided:

It started about 2 weeks ago as a tinny rattle and has developed into more of a knock than a rattle. The biggest problem is that you can only really hear it when your moving.

Anybody got any ideas?

Dr Neil:
Has it got the rubber doghnut on the rear prop? It cud be that. Does it only do it when accelerating away from standstill or backing off?

SteveGoodz:
Hi Dr Neil,

No, there's no donut on the prop. The noise is more prononced when accelerating and almost inaudible when I lift off. It's also there sometimes on tick over but if I put a wheel up on a ramp it stops  :undecided:

Dr Neil:
sorry mate struggling to think what it could be. Does it only do it when it is in Drive or does it do it in Park  and Reverse too?

Yesterday I drove down into deepest, darkest mid-Wales and it was hardly noticeable all day. This morning, dropping the wife off at work, it's quietly knocking again - took about 1/2 mile before it started.

Having got home again I sat with the car idling on the drive. It makes the noise in all gears, neutral and park although N & P are decidedly less frequent. Putting the transfer box into neutral doesn't affect it either. At tick-over the noise is a regular "clunk" but when driving it sounds more like a rattle and it's most pronounced at about 1250 rpm.

Don't know if any of that helps.
