Gearbox Overheats When Towing Caravan

[Jocky]

Bust gaitor letting heat into cabin.
There are proper rubber gaitors underneath the ones you can see on the gearstick. If I remember right the T2 gaitors are bolted on with 6/8 self tappers underneath the consul.

Definately the Gear Box getting hot only when under strain of towing, as posted before it can physically mark yer leg with hot air burns in the cab. under normal everyday use I can drive as far as a full tank lets me (480 miles, 244 Miles Towing) and it's just generally warm as to be expected.

So i'll give the Transmission Oil a change and see how it goes Whats a good type to use and is there a coolant additive i can use in the box that would help too?

Regards

Transmission Tunnel should get warm, but you shouldn't get heat in the cabin that burns you.

Have you checked under the consul to see if it has a bust gaitor seal. Easy to remove its only held on with self tappers.

If you get gear oil make sure its is GL4 spec not GL5 or all the brass in gbox will get destroyed.

If the heat is burning your leg, then the carpets would be on fire also!!!

Is there maybe something stuck up underneath that is obstructing or channeling airflow where it shouldnt..?

Hot air at 80 C will burn you if there for long enough, 60 C water can scald easily.
Does seem like the Gaiter.

If it was made of aluminium instead of rubber, .... Would it be an Ali-Gaiter?

your MPG seems a bit off too, I tend to get abround 25 mpg towing! the extra used by towing seems to be offset by the economy of a long steady journey, could you be having the start of clutch slip? both overheating the box and ruining mpg? it might only be slipping under the extra load of towing?

You have'nt got transmission fluid, it a manual according to you first post!

Oh Sorry Bob My Bad !

Gear Box Oil Then There's Some Sort Of Lubricant In There Otherwise It Would Be A Lump Of Molten Metal.

Surely You knew What I Meant, But Just To Carlify

i haven't read al the posts but im assuming you've checked the oil level in the gear box?

[Gadget2k10]

Nah.. I'm just gonna drop and change Oil with it being cooked a few times it won't be much use at the mo.

hi; all the best advice as usual once youve sorted out what the other lads have suggested I put a drop of slick 50 in my g/box not in diff or transfer box i dont know what effect on them it would have them,I find it keeps the g/box cool and smooth.

thats interesting Plank, could it be an issue with my troll overheating towing.

presume outfit makes progress, so is heat from transmission/clutch or engine
working harder to compensate.

on my recent tug home from wales mainly motorway and of course north bound
always feels more uphill. the car was getting very warm, made one of dogs
in passenger footwell quite lathargic! i thought was just heat in the heater that
was building up til released.

just wondering if would show as lack of umph esp hill climbing?

had tested clutch on stall techniques thought ok prev, but dragging a load
long distances could have this effect.

thoughts welcomed as might avoid ripping rad out of troll, omg whats a clutch
going to cost...

back to the thread oops

[solarman216]

To test your clutch, engage 4th gear, foot on brake, foot to floor on loud pedal drop clutch, should stall engine in 2-3 seconds if it starts to stall then keeps going (as it heats up) clutch on last legs, do not do this again for at least half an hour, this test applies to a car or a 520 bhp truck, across the board, if the clutch cannot take the full power of the engine then it is no good, Rick

PS swifty (my fitter) can do you a cheap deal on clutches, you only have to get the motor here, south coast, Rick
