Gearbox Temperature

Idris uttered summat worrerz funny about:

Surprisingly hot! This is one area where 101's with hard tops and summer are a little incompatible.

I've had allsorts of thoughts to try and introduce additional cooling but for the milage I do it's not worth the bother.

If it was an issue

You can manage one second - it's still 'cold'. The oil will withstand temperatures considerably above the boiling point of water and your hand will not stand that for a second!

View it as a demonstration of just how inefficent gearboxes are.

Yep, sounds right. Get some automotive insulation material and lag the transmission tunnel. Mine always used to draw heat through the gaps around the plate underneath the cubby box too, and it was always drew more hot air into the cabin when the sunroof was open.

So what's the correct grade of oil?

Yes, gearboxes do get hot, and this weather isn't helping. In some situations, I'd wonder if a build-up of muck and dusk were acting as insulation, but the last time I has that sort of problem was with a combine harvester.

That is the only thing that effectively heats my cab in winter. Ihave experienced transmission oil overheating in automatics, it oozes past the seals and catches fire, the solution there is to fit a transmission oil cooler, don't know whether there is such a thing as a gearbox oil cooler.

Thanks for all the replies, take it this is relatively normal then.

I note Davids reference to a combine, interesting, I have marginally more experience of those than Land Rovers.

Correct oils as specified in both boxes.

Will concentrate my efforts on keeping the heat out of the cab rather than worrying why its being generated.

This is correct. Landrovers are devices for converting your money into heat, noise, and a large grin.
