I know everyone else has already covered it but my old BA had a DCS twin plate clutch set up, rattled like hell when clutch was depressed due to intermediate plate rattle and with pedal out rollover noise was amplified with billet flywheel and clutch setup etc. Never did it before I changed clutch and I did regular oil changes with the fully synthetic nulon auto trans fluid (equivalent to transmax z) with nulon g60 gearbox and diff additive and never had an issue and shifted sweet.

this sounds almost identicle to an xr8 I had the other day. had a engine swap and heavy duty clutch thrown in. turns out mounts on engine were f%&ked and dragged the whole box forward with it cause of the engine leaning. drive shaft was only half in the trans

Do you mean g70? I just looked it up and the g60 is auto trans additive, the g70 is manual gearbox and diff additive. Will this be ok to add to mineral dex3 or do you think I should go with a synthetic Nulon oil as well?

I might try the red line lightweight shockproof oil possibly with the Nulon additive unless anyone can advise against it. I have to admit I was a bit surprised when Mal said to use dex, I really want to try something different

I am running the exact clutch you are running. It's dead quite at idle, but very loud when my foot is on the clutch allowing the plates to rattle.

Mine also has large rollover noise at low rpm in higher gears that feels more like a transfer vibration from the solid plates. Also a solid shifter transfers alot of noise.

running penrite 70w75 filled through the reverse switch. 4.8l.

I'm jealous of your quiet box haha. Ahh so many options, gotta make a decision today as to what I'm gonna put in it, pretty keen to try this g70 stuff if Matt had success with it, just don't know what oil to run, I'm thinking I'll try the super expensive red line stuff and if that doesn't make it any better next time I'll try something else, process of elimination haha. I do have a ripshifter with a solid mounted stick so I'm going to put some rubber between the stick and shifter as well and see if that takes some of the noise away. So you reckon an extra full liter gaz?

Few threads around saying 4.8l. I've always run that qty to try and stop roll over but I'm 99% sure my roll over comes from the clutch.

My old button clutch the springs in the plate were loose and caused most of my issues.

I take it you have a T56 gaz?

Ralph mentioned the tr6060 needed lighter oil

I wouldn't put 70w-75 in it. The tr6060 needs a lighter weight oil.
