I had a small issue today while at the trackday, the green cover on the end of the box was leaking, so went to VW at lunch and got a new one along with 2l of gearbox oil....got back to the track and then checked the oil and the guys given me ATF! surely this is not right? I know at the moment it has 70-90W (or something like that) fusch supersynth in there which is supost to be factory fill. so which should I be using? do I take the ATF back or not? the car is used on track alot so I want the best protection for a box that is driven hard. Cheers Karl.
From what I'm hearing from a box builder, gearbox oil is over-rated and a scare sell. Put some Castrol EP80 or 90 in it, or VW equiv. OEM spec basically. That's what I'm about to put in a 6-speed Gemini 02A with a plate diff in it.
so I shouldn't be using the ATF that Ive been sold by VW then? and I should stick with the fusch stuff?
