Hi all,

I have a JDM Pajero 3, 3.0 liter with a 4-speed gearbox. V63W  Pajero - MRUVQ ZR, S4FA/T

I gave car to a friend and received it two weeks later with a problem. At low speeds the car has problems (1000-2000 rpm). at 60 km/h it has some kind of bumps and interruptions.
I thought about bad gas or something. Later I noticed an oil leak from the gearbox.
I left the car overnight and in the morning I saw oil on the ground. I checked the gearbox oil and level  was abouve HOT. I didn't start the engine. I was afraid to kill the Gearbox.
There are no diagnostic errors. nothing at all.
Gearbox oil leak problem - because I can't see anything from the engine.

what could this be?
