Correct Keith. Unless it's the rain splashing on the matrix.

Rain???? ..we don't get much of that in Fleetwood ... Wall to Wall Sunshine here ATM Tony!!!

Thinkin of tootling up to Gassson Dock & havin a walk down the Lancaster Canal toe path this afto .....

Just somewhere nice & quiet you can just sit down & relax!!!!
 
Nice one. But be careful if that bloody mobile food van still goes there. Went there fishing many moons ago, bloody freezing, so had me balaclarva on. Bought a meat pie off him and he put it in microwave, took a bite and the aspic ran out under me balaclarva and took all the skin off me chin. Bloody hurt for days after that. :D:D:D:D
 
The transmission fluid cooler in the L322 is an oil-to-water cooler not an oil-to-air one. The cooling flow comes from the bottom eight rows of the main radiator which frequently gets silted up with corrosion that restricts the cooling flow to the fluid cooler causing the transmission to overheat. A common problem with the L322.

Thank you, that explains a few things. If the poster had have refered to the L322 it would have helped somewhat. Crystal balls have not yet been issued. However i cannot think why anyone would want their transmission fluid to be at engine temperature. I think it is far more likely that the bottom eight rows have transmission oil running through them which is cooled by airflow through the matrix.
 
Well you can think that if you like, but you'd be wrong :)

Ok, but it seems a rather badly designed cooling system were a component that does not normally run at engine temp is defaulted to that temp. That is why they have to use oil which is akin in spec to the hydralic oil used in jet fighter flying control systems. No wonder these bloody things break down.

I would think so but possibly not with the rad in place.

Thank you for clearing up this ..I had not realised that the L322 had this type fitted .....it is Identical to the Mercedes system (From 2000 onwards) .. they had horrendous problems with their "VALEO" type radiators ..( The oil coolers Split & mixed rad water with Gearbox Oil .........

I would strongly suggest you pop over to Mercedes-Benz Owners' Forums & type in "VALEO" in the search box.

I am also a member over there (Having an E240 V6) all your questions will be answered by the VOLUMES of posts there relating to this type of Gear Oil cooling

Seems a bit of a strange one to me. Under normal conditions unless you are towing a house around behind you, the transmission fluid won't get anywhere near to engine temp. To default it to that minima seems ridiculous to me. But cleverer people than me at Land Rover, so you have to take it there is method in their madness. I would have thought that setup would be foreseen as a problem by a blind mouse, being chased by a deaf and dumb cat, with no ears, no tail and only three legs, called Lucky. Unless the designer was seriously demented. Or could the cheapest manufacturing option come into play here?

Hmm thats interesting, I always thought that auto box oil ran at very high temperatures due to the shearing effect in the torque converter.

I suggest that the water/oil system is possibly a means of stabilising the temperature of the auto box oil in very cold conditions to provide smoother gear changes.

Yes it does get fairly warm. But go for a run and hold your hand on the top of the rad for a while, then on the auto box casing. Bet i know which one you will lift your hand off first. Might be an idea to run cooler pipes from front and rear diffs and super heat those as well so everything fails at once when the rad blocks up. It would save a fortune on diagnostics just replacing everything. There must be a reason for it as you say, but i'll bet the oil in your P38 box runs at nothing like engine temp. Unless as i said earlier you are towing a house around. Personally i think it's bad design or a bad idea or a combination of the two.
