Hi mates!

Just bought my first car and now I'm the (very) happy third owner of a fantastic condition, non-abused '05 XR6 (BA MKII, non turbo, 4 speed). It's a joy to drive & I want to keep it running smooth for as long as possible- but I have been reading about the coolant & transmission oil mixing on some of them and it's got me a bit worried.

I'm wondering how often does this happen? Is it due to being thrashed or do they simply wear out with age and mix eventually, regardless of how well the car is treated?

At what KM's do they generally start mixing? Mine is at 187,000 now.

I've been looking at buying one of these PWR transmission oil coolers- has anyone had any firsthand experience with one? I'd happily pay $250 for a preventative measure. Really don't want to be replacing the gearbox.


A side question I also had was what is the best interval to service these at? I read somewhere every 10,000KM's- is that about right?


Cheers guys,

dan
