quick gearbox question

If the transfer box is in neutral and the gearbox is in gear, the gears will be turning but not the wheels and so the oil in the gearbox will start to warm up with the vehicle stationary, is that correct?

A little bit, the gears stirring the oil will put a bit of heat into it. Might take a while, though.

I'm with @Turboman , it might, possibly .... what are you trying to do ?

I just want to warm it up a bit to do an oil change really, it's a job I've been meaning to do for a while, I could take it out for a run but it means shuffling cars around so the cretins who live opposite don't block my drive!

The oil (ATF) in the gearbox is pretty thin (as its pumped) to start with. It's not thick and gloopy like the oils in the transfer box/diffs so unless it's below zero it should pretty much run out anyway.

yes but will be idling for yonks before any really heat gets into it, will drain out fine cold tbh, it’s pretty thin anyway

It will be fine, just give it extra time to drain.

Thanks all, seems like theres a general consensus there! Didn't get round to it in the end, somehow I found myself with a couple of takeaway pints from the 'jolly fisherman' and nothing very productive got done after that!
