Thread: L322 AFTERMARKET TRANSMISSION COOLER INSTALLED

but three transmission specialists in Melbourne and Bendigo told me that they could not find enough space to fit them.

Yes, that is also what they are telling me. From reading the UK site it seems that the problem is mostly with the 4.4 engine, is it unusual to have this problem with the TD6 ??

[Have had the same problem. Would like to know what size and where did you get your cooler from. Cheers charles

QUOTE=tebone;1656646]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.
