hello every one

bizzar sound coming from back of the car when i change gear from D  

to  R(( just when i leave the break)) idont know what it can be ?? it

dosent feel from gear box.

it s more from back wheels...i ckeck the disc and pad they seem good.

one things i notice is it happen when im up hill or down hill

on flat ground smoth and fine .

what do you think??

[Marks DTM Calib]

Dont really know....handbrake all ok and working fine.

Describe the noise?

[feeutfo]

my old cdx used to bang on engaging reverse when the atf was low, but the brake never came into it, the breaks used to 'creak' a little if you didnt have enough pressure on the peddle. Neither really sound
like your description tho. Strange one.

hand break fine .hardly ever i use hand break  

sound like bang when i press the break and

puting in D for 1 secend

once it run everything like before.

i was thinking maybe i should put some oil in gear box

Auto transmission fluid, change it and I think that should cure your problem.  Sounds like the clunk is down to the box from what you describe.

[Hog]

Have a look at the fluid it is usually red in colour (or has been on other autos that I've changed it on, can someone confirm that on the Omega?) which can end up almost black, if it is black then defo needs changing.

i changed the oil and gasket 9k mail ago .i cleaned the sump

too. the thing is i fill the sump with those red oil and put i back

i mean both sump . so stupid dont you think?

i remember i only use 4.5 liter oil and maybe i had to put more

[Dave-C]

Perhaps worth a level check first

Do you mean you filled the sumps and then bolted them back on?

That is not the correct proceedure and if you only put 4.5 L in then you will be short by 2-3 litres - not good.

You need to fill by pouring through the plug hole in the big sump via a pipe of some sort WITH THE ENGINE RUNNING.  When it starts to overflow, that is the correct level.

Are you sure you don't have a differential problem, it sounds remarkably like the symptoms I had a while back. Mine felt and sounded like the rear brakes were binding or scraping on something, but brakes/discs where ok. The problem and sound of grating sound got progressively worse under hill conditions - up and down. I hope it's not but worth looking into as unfortunately they cheap - I had a grateful donor provide me with a replacement as new one from stealers was quoted at £1800!!!!!

i ll buy 7 series with that money...


check the gear box and oil start to come out when the bolt was

hlaf way out . so no low ATF

sound like it s from diff   put the car on ramp and check everything

slight oil leak in fornt of diff. so try to top up the diff but agine

oil start to come out when bolt was half way ...

i think i need to change the car before anything go so funny

Gearbox wise get the engine running and up to temp and take out the filler bolt...if there is gearbox oil coming out still then the box is overfilled...which can be bad for the gearboox too...let it come out

If diff is leaking from the front seal I believe the seal can be replaced???

Good grief!! I would never consider selling a 2nd hand diff for more than £100...maybe I'm giving them away at that price lol
