MKIV Manual Transmission Fluid

[dubbed]

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.

syncro

Syncro on reverse, I think only T3 syncro's had that.

Definitely MT90
no syncro on reverse, it's a straight cut gear.

I still haven't gotten around to doing this

at risk of sounding noob, if gear changes feel fine is there a need to change mtf at all? even after xxx kms and xxx years?

Gearbox oil should be treated as a normal service item, albeit at longer intervals. I'd probably suggest every two years or every 50,000kms.

IMO MTL. MT90 is a bit thicker but very good at the same time, both have great frictional properties. Older or higher K boxes love Mt90.

Can anyone point me to the right Gearbox oil to use in my 02J box with a freshly installed WaveTrac LSD..The instruction manual for the lsd says not to use the following:


When using Wavetrac

use Factory spec oils for your car
use factory HIGH compatible performance oils if u wish to upgrade the oil


do NOT use gear oils with Friction modifiers or limited slip additives
do NOT use Shockproof or similar gear oils designed to reduce Friction

So what is the best oil that meets all factory specs that will be safe to use with my LSD.. the guys who rebuilt the gearbox recommended Penrite Transaxle 75 Gear and Trans oil Semi-synthetic SAE 75W-90 as they said it has the same additives as the Penrite Manual Gear oil 70 i think he said.

Im not sure what to use now because i wanna use the oil the gearbox place recommends in case for some reason the transmission fluid destroys the diff and at least then they transmission place will be at fault? but at the same time im reading conflicting answers on the net about what to use.. mind you there's not much on what oil to use as most people don't have the LSD to work about and just buy shockproof and oils of those sorts.

Can someone please shed some light as to which oil i should be using

Thanks in Advance
