Hi CRJ ,
i tow heavy trailers over long distances with my 90 and i have never experienced this. i usually have a bottle of water and chocolate in the cubby box, neither has got warm. it could be your handbrake shoes are sticking/out of adjustment which would give you a huge heat build up from the friction but normally you would also get a knocking noise when slowing down caused by the same fault. or your gearbox is poorly! |

I am pretty sure it isnīt the brakeshoes. I noticed that the transferbox also gets very very warm - you do not want to touch it! I was thinking about heat from the engine going backwards but not that much! The gearbox seems ok - no trouble changing gears etc.

Hmm its a strange one matey,
can you touch the handbrake drum or is it too hot ? it should be warm but cool enough to touch. daft question but is there enough gear oil in the transfer box ? |

On every Landrover I have ever owned (a fair number now) the gearbox has got hot on a long fast-ish journey or when towing, so I don't think that this is actually unusual. On my Puma, I don't really notice it inside the cab on normal journies, but go for a longish run up a motorway or dual carriageway and the centre tray (no cubby box on mine) is quite warn to the touch and the seatbox behind the gearbox is hot.
If you are towing and running at speed I would certainly expect this. Remember that a gearbox is not at all mechanically efficient and will generate heat from the internal friction. On the 6-speed Puma box I woudl expect it to run cooler in fifth (ie direct) than any other gear; sixth is an overdrive gear and will generate more heat than 5th. This is why many gearboxes are fitted with oil coolers. |

yes that's normal in a landy.....there is not much you can do about it.
i open the engine bonnet to let it cool down after a long day driving. |

I can feel the heat through the seatbox on mine when towing, the heavier the trailer, the hotter it gets! That said, I havn`t noticed it inside the cubby box. 2011 110 USW

My 110 does the same thing. On a drive across Germany last year in 30+ degree weather I thought that I was going to boil to death. You couldn't touch the exposed metal on the back of the seatboxes, it was so hot.
However, I was told over the weekend at Billing that the Noisekiller foam can keep the seatboxes/floor/gearbox tunnel moderately cooler. I didn't have the funds to get the kit at the time, but it does interest me. |

I did 5000km in over 35 deg cel outside temps, the Land Rover was well overloaded pulling a boat and sitting at 105kph for all but the rough stages of the trip, 500km on very rough dirt road. The hand brake lever got hot as hell, in fact I put the air con on to cool it, but the gearbox seems to have suffered no ill effects at all on our return to Perth. Other than a cooked egr, dust entry and the ongoing Defender moans i.e window rattle its almost trouble free. If the gearbox puts up with this sort of treatment I don't think you will have any heat problems in with it in Europe.

Before I bought the Puma in 08 I had a look at what the Australians thought of it. It was posts like Allan's above that persuaded me to go for it. I figured a Puma in the outback or very long hot journeys would get more abuse than I could throw at it. So if it is good enough for the Australians,it is good enough for me-and anybody else for that matter. 1982 88" 2.25 diesel 1992 110 200tdi csw -Zikali 2008 110 2.4 tdci csw-Zulu 2011 110 2.4 tdci csw-Masai |

Might be worth checking that your gearbox oil is still in good condition and has not been cooked, turning black.
Oil suffers at high temperatures, loosing its lubrication and cooling properties and can kill the gearbox overtime. Steve Defender 90 TD5 Station Wagon

Thanks for all the replies - will change the oil this weekend, and be happy about having a place to keep my coffee warm...
