Hey all,
Was wondering, is the stock ZF transmission cooler the culprit for causing the ZF to milkshake (the image below)? Is it because the coolant and transmission fluid run through this heat exchanger, and as it breaks down this is where to 2 fluids mix causing it to milkshake?
If so, would it better to change the stock transmission cooler every 80,000kms with another genuine one? Or install a PWR heat exchanger? Cost isn't a problem but which would be better in the long run?
Cheers
