i have a 97 cinquecento sport and the other night i was dropping my girlfriend out and i was on back roads most of the way and hit a couple of pot holes and when i went to collect her again i started the car and it sounded a bit off really hard to explain kind of like the engine was after getting louder but its coming from the gearbox side and first and second gear are gone silghtly tight i had a look round it but cant seem to find it as only make the noise when driving goes away wile free wheeling or under light acceleration go heavy on it and it starts squeeking/rattling coming from where the clutch lingage goes through the firewall ive put oil on it but its still persisting :( might there be no oil in the gearbox? thats what killed my last cento any advice appreciated :)

check the gearbox oil anyway, no harm in doing so :)

get someone to sit in the car and press the clutch with the engine off while you have a listen under the bonnet, repeat with the engine running and car in neutral, with the clutch up give it a bit of power and listen for any whirring around the gearbox

If it was leaking from a wet inner gaitor on the drive shaft then you need to walk to the motor motor factors for a new gaitor kit and an oil refill pack for the box, the leak you can see could be the last few drops of oil in the box.

Unscrew the filler plug stick pinky in ... as above

The oil should come in a plastic bottle with an extended or extendable tube, put tube in filler hole and squeeze until oil dribbles out. You should be able to do this with the car on the road, donno for sure though as my sporting is different.

Sorry

Hi

If the auto is nice a replacement box from a breaker should not be too expensive. Get gfriend a set of overalls and inspection gloves.

Think most of the sportings had dry inner constant velocity bearings.

But you still need to keep the bocx topped up.

How did you check the rear mount for play?

Please buy more box oil & add to box until it comes back out filler hole. Where was the oil leaking from?

Hi

You need to visually inspect the metal elastic for signs of displacement from its normal status, take a flash light and mobile phone camera under with you... Nice sexy rubber pic please.

The engine needs to be clear of exhaust...

They normally flow through the plate bolted to the auto...

There is also the box oil leak, if it is from a shaft seal you may be able to replace in situ, donno some one will confirm.

Please identify where it is from
