Hi.

Is it possible to drain/refill the gearbox oil with the box still in place and with the car on the ground, or at best on axle stands ? If so, what's the best way of doing it ? Also, what would be a suitable oil and where's the best place to buy it ?

Many thanks.

 

Whip out the driveshaft to drain the old oil, refill from the filler plug on the front.

Any car shop will sell 75/90 oil
