I did an oil change on my automatic gearbox 722.9, the car comes with start-stop and the VIN decoder shows the fluid to be the Blue type. However, the fluid that came out was redish (burnt) colour and the pan had quite a bit of sludge but no metal filings.
I drained the converter but I didn't flush the cooler, the fluid coming out of the pan after draining at 45C was already looking darker but I only had 10 litres of transmission fluid and the car was booked for an MOT the next day so I had to pack it up as it was.
The car actually feels a lot nimbler and the gearbox seems to be working fine but there are a couple of things niggling me.
Do any of you know if there's an aftermarket transmission fluid for this gearbox that it's red in colour and the previous garage might have used? Or has the car been running on the wrong fluid for a long-long time?
I might end up just doing another fluid change but it's a pain the backside when you don't have a car lift, that's even before you take into account the cost of the fluid and all the parts!
