MKIV Manual Transmission Fluid

**dubbed** · 09-10-2008, 12:16 PM

Hey chaps,

I've tried searching Google, these forums and Vortex but I still can't fine a definite answer to this: what Redline fluid do I need for my MKIV GTI manual transmission? I've seen MTL, MT90, lightweight, shockproof etc but I don't know what to choose/look for specifically. Will I need MORE than two litres to fill the gearbox?

I am also considering Royal Purple fluid - has anyone used it? If so what specs should I look for?

I am hanging out to change the fluid and get back my slick gear changes!

Thank you

depends on how the box feels .

I use mt90 on most applications and heavy duty shockproof for those that crunch gears .

You'll need around 2.5l

Thanks for your help mate! It crunches rarely when engaging reverse. I will opt for the MT90.

Much appreciated. Cheers Bug racer

Royal purple make quality fuels just make sure you match the thickness of your oil. Reverse crunch could be a sign of synco wear. But your spot on by doing a gearbox oil change first.
