I bought a 2008 G6ET recently and as part of the deal, I got bought a reduced price PWR external heat exchanger.The fear of the 'milkshake' is always something that has stuck in my mind... It did with my F6 and with this car. So as to protect my ZF, I was under the impression that an external cooler was somewhat fail-proof. My understanding was that an 'external' cooler would not utilize factory fluid transfer points thereby eliminating the chance of the coolant/trans fluid mixing should the cooler fail.Got into a bit of an argument with some Facebook chap recently and he seems to think that the cooler does not eliminate the chance of a milkshake which is not good news at all... A number of facebookers seem to just troll and answer questions for the sake of it but now I'm questioning if this will work.Can anyone please let me know 100% if an external eliminates the chance of the trans failing due to fluid mixing? It's a big commitment to buy the cooler, get it fitted and service the box if it's all for nothing...Thanks Gents,Dan Link to comment Share on other sites More sharing options...

Unlike the factory item it is very high quality. Do not be scared of it milkshaking. A proper oil air trans cooler does not run the coolant through it. Unless you are doing circuit days in summer, run the PWR exchanger mate. It won't let you down Link to comment Share on other sites More sharing options...

I was under the impression that the cooler would fill with trans fluid to cycle through and as the car was driven, the air would lower the temperature of the oil in the cooler... Guess I was incorrect in thinking that the coolant wasn't involved...It is reassuring to know that the build quality is there though Cheers guys, Appreciate that.Dan Edited 13/10/14 10:17 AM by NVT Link to comment Share on other sites More sharing options...

Sh*t...What do you guys suggest? Sell this one off and buy an oil to air? Or just stay with this due to the build quality?Ratter, for road applications and longevity what would you recommend?Thanks guys!*EDIT - Thanks Seaton * Edited 13/10/14 10:51 AM by NVT 1 Link to comment Share on other sites More sharing options...
