I installed an AT cooler for my A33 just like I did for my A32. I bypassed the original cooler in the radiator so there is less heat load on the radiator and so that there is less change of the AT oil going pass 90deg. Most of all why I do this is because there will never be a chance that the AT oil cooler in the radiator to spring a leak and destroy the trans or fill the whole engine cooling system and block with sludge mixed from radiator fluid and trans oil. Where it actually happened to a friend of mine and that wasn't a pretty sight. Have had this setup running for almost 300,000km on my A32 VQ30DE with 40,000km-50,000km AT oil changes and still running the same auto trans and the trans still feels healthy.
Since I just bought an A33 VQ20DE (130,000km) so I decided to do this for it as well.
