Hi,
The main reason for the oil leakage is most probably due to the rear crankshaft seal.
First thing to do is check the engine breather is clear. You can clean it with isopropyl alcohol and dry with a heat gun.

Trouble shooting 2009 chev.aveo gearbox leaking oil on pan gasket how do i repair the leak on the gearbox


Determine if it trans fluid(red) or engine oil. If the trans pan gasket is leaking, drain it (By slowly remove the pan) and replace it. Don't use the rubber gasket. Use cork or silicone. If oil, coming between the engine and trans. This would be a rear main seal on the engine. Trans has to be pulled to replace it.

I have a nissan 1400 champ and is leaking oil on the front part of the manual 5 speed gearbox and the rear part of the gearbox. I have replaced the crankshaft oil seal but i still have oil leaking on


There are seals on the front and rear of the transmission. If the clutch wasn't covered in engine oil, then replacing the crankshaft seal wasn't necessary. Reseal the transmission.

My ford focus is leaking oil think it might be gearbox oil,


Is the oil you see reasonably clean or is it black. The gearbox oil would be cleaner than the engine oil. Gearbox leaks would most likely come from one of the following:-
  1. Drive shafts
  2. Gear change lever inputs,
  3. Speedo cable
  4. Reverse light switch
  5. Drain plug
  6. Input shaft seal (inside the bell housing).
Pig a piece of paper under the car when you park it at night to give you an idea where the drip is located and inspect the area above that position

Transmission fluid level need regular top up and there is no external leak.Fluid color looks white.


If no external leak and the transmission fluid colour looks white, the problem belongs to the automatic gearbox oil cooler. The oil cooler has broke mixing the gearbox oil and coolant causing this milkshake. It's a small radiator core type oil / water heat exchanger. It is cracked inside and transmission oil is mixed with engine coolant. Because the transmission oil pressure is greater than engine coolant pressure, the transmission fluid level drops. See also the coolant colour inside recovery coolant reservoir inder bonnet! It could be like this:

The transmission is leaking in front and middle of the engine. What is the problem and how can I fix it


could be your gearbox seals.Check if the front one is gearbox oil or engine oil.If it is engine oil then could be your rocker cover seals..oil from the top travelling down,sump gaskits or crank shaft seals.The direction of travels pushes oil towards the rear and sometimes we think that the leak is on the rear somewhere whereas it could be in the front.

How to fix oil leak from top of a manual gearbox housing


sorry but its going to be a big job. you need to remove the gearbox to open up and get to the seals. you could try and use an additive in the gear box, its like oil seal for engine you can get it for engines gear boxes and difs and power steering. it sometimes goes by seek and seal, in older vehicles its quite good. you will need to replace the oil it will need to be done twice to clean it all out so it can get a good seal.. i.e change oil run engine get the gearbox to move for 20 min then change the oil as its warm not hot so let it cool down for 10-20 min then drain. put the seek and seal in and top up with oil and run as normal, check after a few days to see if its worked. usual does.

Leak between the engine and the gearbox


Try using high mileage oil and lucas additive...If leak is not too bad, that may soften and swell seal enough to stop it. To do seal correctly engine must come out.
Try it...It may help!!!
