Did you bypass original cooler & what were the adaptors for. What cooler did you use & did it have a fan with it. Any pic's
Had been told by a mechanic that needed 250psi cooler. Ones I've looked at only 100 psi
Thanks Gary
Hi Guys FYI,
I just installed an aftermarket transmission cooler just behind the grille. In the past I've had trouble with the tranny getting hot and staying in 3rd gear until it cooled down when towing a caravan.
I've just put the l322 to the test towing up/down a steep hill where it would normally get hot and stay in 3rd gear.
Test results: Tranny stayed cool and shifted through all gears no problems. You could even rest your hand on the cooler with out burning it.
I failed to mention its a ZF5hp24 (petrol 4.4).
The original cooler has radiator water flowing through it all the time to heat/cool your tranny fluid. I believe this was the problem not allowing the fluid to cool quick enough. I think this is good for cold conditions but not towing in Australian conditions.
The two flexible hoses that go to this cooler unclip from the cooler. You have machine two adaptors that will plug into the hoses so you can attach your aftermarket hoses and cooler.
Also I serviced my own transmission, installed new filter. Its quite easy the tranny took approx 6 litres using Nulon oil. You have to allow a little more oil with the new cooler and pipe work.
Filter $75
Oil 20Litres $230
Cooler/piping $120
Adaptors $50
Ps. Keep the transmission cool and change oil every 40k and you shouldn't have any problems.

Hi Gary,Originally Posted by 33chinacars
I used a plate finned cooler instead of a tube cooler. I did bypass the original cooler. I'm not sure what its rated to but 250psi in the cooler line seems very high. I made a male adaptor piece to slide in the original flexible hose which has two orings inside. The way it seals in there it wouldn't be rated to 250psi (I could be wrong)
I don't have any photos but I could draw up the adaptor piece to show diminsions this would save you cutting original flexible lines.
Cheers Paul

Hi, Just wondering were you got the oil cooler from? Any pics? Sounds like a good answer to a L322 popular problem.
I just come back from a easter trip in the Vic high country ( Licola ). I was towing my van and using the gears on the sports mode after a very long series of hills the auto locked in 3rd again, not happy!!!!!!!!!!!!. I stopped and put my hand on the cooler it was hot but not extremely hot its got me guessing what temp it goes into 3rd. I've just bought another cooler tonight of ebay. I will be running two coolers now both are 280mm x 180mm x 19mm thick, hopefully this will fix the problem. I will take some pics when I fit the next cooler and some pics of the adaptors as well.
One thing I noticed the fluid cooled down alot quick than originally which allows full selection of all gears.
Has anyone else exprienced this before transmission fluid getting hot and locking into 3rd gear?
Regards paul
can I also get a copy/drawings of those fittings, romar49@bigpond.net.au thanks Roger.
where did you buy the cooler and what type/grade tranmission oil do you use
