I own an 80 series petrol manual. On long trips the gearbox and area just in front of the floor pan gets very hot. It'll get to a certain temp and remain there. The heat on the driver's footrest becomes just bearable (when barefoot) and when resting my left leg against the gearbox housing it also becomes quite uncomfortable to the point of keeping my leg away from it. This has been going on for the last few years and I've just had the whole underneath serviced, new clutch, diff & gearbox oils etc.
The engine temperature remains constant and never had a problem with it overheating.
Has anyone had problems with this in the past? Is it normal? I know with the a/c on it cools it down a bit but with it broken we find more heat coming through the firewall then from outside on a hot day.
I visited 80s owners online but there's nothing there re this problem.

Chris,
sounds pretty normal to me,
well by that I mean
mine is the same. If you hop underneath and touch the gearbox/transfer case you'll find them extremely hot.
Not having carpet etc probably reduces the insulation capabilities also but that was my choice.
There's some very clever people that
check this
forum out and I'm sure you'll get some great repsonses from other 80 series owners very soon.
cheers

Hi Chris.
My GQ Patrol had me worried with exactly the same symptoms. My High/Low selector lever got so hot I was reluctant to touch it. I added Morey's oil stabiliser to the transfer case (50%) and gearbox (10%) and there was a dramatic difference to the temperature of the lever and the floor area around the gearbox/transfer case. I also added it to the rear diff (50%) and the front diff (20%) with a noticeable heat difference to the rear diff.
We aware that these products (Moreys, Flashlube, etc) all have a definate useful life and ahould be changed regularly. I change
mine approx every 50K. Otherwise it works
well heat-wise and I believe must reduce wear.

Chris on all my vehicles I've removed the floor mats and then cut those closed cell foam sleeping mats you buy at Kmart or similar to fit all over the floor and up the firewall as far as you can reach. On the trans tunnel, up under the seats and firewall I glue them on with contact glue (gel type works best with less mess) while on the actual floor area I just cut them to shape and sit them on the floor.
Refit the original mats and seats etc, you will notice a big difference in heat and noise transmitted into the cabin.
The mats are cheap, don't hold moisture and the ones in the footwells can be removed for cleaning.
And yes the floor in all my vehicles have got too hot to touch in summer especially the first 1970 FJ40 with no floormats!
