Hi Dave, thanks for the reply. yes it is just a service, I’ve owned the car for around a year now and the car has now done 85,000 miles and through further research people are advising fluid change for price of mind as there seems to be conflicting advice on when the fluid needs changing so I wanted to be safe than sorry. thanks for the heads up about alternative fluids. Like you said it may just be worth going for the ZF oil as they seem to offer a service pack with the oil and filter/pan for around £250 which I don’t think is too bad. im pretty handy with the tools, would you say it’s fairly easy to do yourself with the correct torque wrench and oil pump? also how do you flush the converter?

Hi Guys, I'm new here and joined to seek some advice regarding transmission fluid change on my 640d I've heard a lot of hype about the ZF8 gear oil, but have been looking for some alternatives solely due to the cost of the damn stuff. Millers claim they produce the same spec ZF8 oil and its literally half the price. I've used Millers many times over the years in some high performance cars and always respected their fluids but has anyone had any experience with their ZF8 gear oil or can anyone recommend an alternative to the crazy priced genuine ZF8 oil also just noticed Smith Alan also produce one of the same spec called 'Trangaurd ATF8' Any help or advice would be appreciated
