ive got a oil leak from my auto gear box and it drips onto the exhast when ive got the car hot and been driving for 30 mins.

it only drips when you put your foot down not round town

had the car on the ramps today at the garage and we are stumped the box is oil free no leaks from the seals but oil all under the car on the floor pan.

you can see it dripping from the gearbox area when it goes but thats when iam on the road and not on the ramps in the garage :confused:

is there a over flow pipe?

the only thing done to the box the filter was cleaned

any ideas as ive run out of them and iam geting sick of smoke coming out the back as if the turbos have gone.

p.s. turbos are fine!

Are you sure that it is not leaking as most Z's do from your rear Crank seal ??? I have had more than my fair share of oil leaks and I'll bet my Bottom $$$ that it is coming from there...

the bottom of the engine is dry no oil anywhere the oil starts from the back of the auto box but where i havent got a clue

the only thing i could think of is when we refiled with oil after cleaning the auto box out is that we over filled and when i put my foot down it presuring up and chucking out a oli breather? or over flow pipe ??

....the filter was cleaned - as in auto transmission problems - bits of dying box clogging the filter?

 

you mean the sump was dropped and the box re filled with new transmission oil too?

 

It might have been seriously over filled - take it you checked properly, but to get on the exhaust it would need to leak out of the tail shaft seal and be spun onto the exhausts and all over the underside. But that would only be from the tailshaft seal backwards. If its further forwards it might also be thrown out of the filler / dipstick tube or seal or even the icky little breather pipe on the top side of the gearbox body.

 

The days before my transmission died I had oil smoke smells and smoke rising from the back of the engine when the bonnet was up. I thought it was an engine oil leak but after the box died I realised the smoke was from overheating auto transmission fluid and the smoke comes out of this little breather on top and up the back of the engine. Eventually no drive and nasty noises after only a few minutes running. Oil under pressure squirting out there could fall on the zorsts. Also check out that the oil cooler banjo pipe connections are on right and its not leaking from them.

 

Hope its just overfilled in which case correct it quickly

 

a box change is pricey

just check the car the drip is coming stright down where the exhaust pipe splits into the V. IF THIS IS ANY HELP

went buy the book on the amout to fill what is the right amount to fill a auto box from empty

to fill the box from empty - it needs less than 5 litres (maybe only 3.5) if only the sump was drained as a load stays in the torque converter and cant be drained unless its off the car. The total is a lot more. If you put in the amount as in the book you have overfilled it. Nice new oil is very clear and hard to see the level with. Mind it has to be running to check it and had been in D and r a few times while running to be sure the fluid is all around the box otherwise it looks too high on the dipstick. Sounds like it might be squirting out the breather. The pipe faces backwards on the top of the box.

 

Suggest a bit of the narrow plastic pipe for windscreen washers from Halfords and syphon the excess out through the dipdtick tube

it sounds like theres to much in the box!

i think we put in 5L as recomended but the box was empty BUT there could of been a 1L still in? hidding i will try and take some out and see what happens

My exhausts are totally covered and stained with oil all the way down to the backboxes just from having the Rear Crankseal Still DO NOT rule it out you will be suprised how much the oil will travel during motion of the car.

Is it an engine out job to do the rear oil seal???

Chrsi

Auto fluid does expand when its hot too.

No mate you can get to it if your car is up on a ramp and gearbox is dropped.
