gearbox oil leak

[agmgranturismo2006]

i found small gear oil drops on my garage floor so i raised the car and checked cv axle boots it was ok and found the leak coming from the area where the gearbox is connected to the engine and bolted to it by studs i am checking the gear oil level now frequently and its with in range so what can cause such a leak?

Do they have a gasket? That might need to be replaced.

If it really IS gear oil you found then a seal has gone bad.

More often its engine oil from an aged rear main seal.

Most likely your driver side axle seal. When this is leaking, it runs down where the tranny meets the motor.

So:

1. Remove the hubcap, and spray some liquid wrench on the axle nut, and use needle nose pliers and pull the pin.
2. Loosen the center axle shaft nut. I forget what exactly mm it is, but it's big.
3. Loosen your lug nuts.
4. Raise the front of the vehicle.
5. Remove wheel.
6. Grab a 23mm socket, and remove transmission oil drain plug. And drain the oil.
7. Pull the brake/disc assembly and move it out the way.
8. Grab a pry bar, and pop the axle off the tranny side.
9. Use a thin flat head and a light hammer. Gently tap on the edges of the old seal where it meets the tranny, and pry it out.


10. IMPORTANT PART: Make sure you identify exactly what transmission you have. Look all over and identify what transmission serial number you have. Because autozone carries like 5 different seals. And some are very expensive, while others are reasonable.

11. Give the car a good Clint Eastwood stare before going back under.
12. line the seal up and gently tap it back in. If you find a socket large enough that is the same diameter as the seal. That is good to use as a tapping reference getting a nice even sit.
13. Pop axle back in..
14. Re install the brake knuckle on the other side of the axle.
15. Install nut
16. Re-install wheel.
17. Lower the car
18. Torque down on the axle nut like a mother. Re-install pin.
19. Re-fill your transmission with fluid. 10w30 or 75/90 gear oil. Or with the correct auto tranny fluid if you're an auto. Re-fill from the top by removing the stock intake box, and there should be a 17mm bolt up top.

Thats pretty much it if indeed that is the problem.

thanks for the detailed info but i have already replaced my axle seals recently and the leaking is coming from inside the gearbox actually from the rod that carries the clutch mechanism that rod is running through a seal that is the seal that is leaking currently in my car because the oil is coming directly from the transmission case
