First things first.

To do proper analysis you must be able to see where the leak is coming from.

Totally degrease and wash the gearbox and motor so that they are completely clean of dirt, oil and grease.

Top up the gearbox and motor with the appropriate oil to the specified level.

Drive the vehicle for 10 km/5 miles and return to the workshop.

Inspect the motor and gearbox for tell tale signs of the oil leak. Follow the trail of oil to the source.

If there is no direct evidence then repeat the drive cycle for a further distance and reinspect.

Acquire the gearbox seal/gasket kit, remove gearbox, follow the Factory Service Manual instructions to replace the failed seals.

Easy.

Anything else is just wasting time and money.

I agree with the above post. A dusting of talc may help you see the trace of oil.

Hi vishnus.2184,

There is a dye you can add to the gearbox oil that fluoresces (glows) under ultra violet light. It can also be used in the water system. Try Google.

Best regards,

John

If the above does not disclose where the leak is coming from, try draining the fluid in the transmission out, and replacing it with mineral spirits. The lighter viscosity of that will make leaks easier to spot. Do not drive the vehicle with the mineral spirits in it. At most, just start the engine, and let it idle till it warms up. Good luck.
