Sometimes when briskly dropping a cog to 4th from 5th on the motorway, I get a crunch on the downchange.
I have had similar issues with other gearboxes in the past (Evo 5-speed), which have been almost completely cured by using certain types of gearbox oil.
What is a good recommendation for a gearbox oil for my 6-speed gearbox?
One of the best I have used in the past is the Cusco Mission Oil 75W-85 GL3.
Is this suitable for my gearbox and has anyone used it?
Any other recommendations?
The search has recommended various oils, Dexron II ATF, 75W-90, Shockproof etc.etc. - even emails from Getrag stating GL3 75W-90.
