Gearbox Overheats When Towing Caravan

[solarman216]

Getting back on topic, something is wrong here, manual boxes do not get hot, towing or whatever, certainly not hot enough to feel the heat in the drivers and passengers foot well, this needs further evaluation cos if the box is getting that hot it would be molten metal by now, Rick

Hence my quesrions, is there any oil in it? could the clutch be slipping under the extra load and generating heat?

Took truck to garage today, it used 1/2 litre oil to top up, transmission casing was topped up too again very little needed. stripped out centre console and removed gear stick gaitors to find them well and truly perished and not fastened down properly, got replacements on order and should be available tommorrow. Will see how that helps

Hi there,

did you get to the bottom of the g/box overheating as my new 2003 swb tdi is doing it pulling my van after about 50mls or so, the gearstick gets really hot, i will change g/box oil this week and replace with valvoline 75w-90 gl4 .

Well just to get the other side, I towed a car trailer with a Terrano on it and a spare engine in the boot from Brighouse to Bexhill 300 plus miles almost non stop at speeds that were more than a little high and the gear lever was only the same temperature as the inside of the car, even the engine did not get too hot on the toughest of grades, and the gross weight was 4,8 tonnes oh and it still did more than 21 to the gallon, Rick

I had mass amounts of hot air escaping through the gearshift gators into the cab (enough to burn ya leg as it did) and it wasn't just bottom of gearbox but the whole thing also the gearstick was very hot too.

However since topping up gear oil in box and transmission casings and replacing gear shift gators, I took me old trusty tentyhouse away for the weekend up n over hills galore in Huddersfield / Halifax area and since then the truck (t'old Frank) has been running sweet ,, Problem solved

Hi all,

Changed all the oils yesterday rear diff ( not LSD me thinks cos it only took 1.3 ltrs ) G/box and transfer box and then front diff, after removing sumpguard and all the bolts came out without snapping them (unusual or what ) so now i'll be using the van in acouple of weeks and check temp of gearstick and box.

watch this space.

I thought they all had an LSD

Hi plank,

that's what i thought, but i'm sure i read it some where that the later ones were not LSD, the diff is different to my 97 one, as the diff bolts on the2003 model are on the back of the casing and the 97 model are on the front.
someone on here will put me right in due course.
