I don't use Redline, but I'm going to answer your question anyway as best I canDid a search and didnt find the info I needed. What weight / viscosity do you use for tranny and rear diff. as well as quantity for both. Any help would be appreciated.( oil used and amount for both) Thanks Jim
it has since been proven that our getrag gearbox has some significant differences compared to the toyota supra getrag gearbox, so redline should be fine. I've run it in my gearbox and diff for >50k miles without issues. I changer it every 25k miles or so.ps. As a side note, search for "Redline transmission". That should bring up more information than you ever want to read, including several documented concerns that Redline and our transmissions are not compatible. Whether that has ever been definitively proven I do not know since I use RP.
2 Quarts of each? or?Redline MTL gear lube for the tranny
and for the rear diff 75w-140 gear lube
I think you may have a better chance of getting an appropriate answer by posting in the M6 forum.I wanted to change my trans and dif to red line but was told by the service manager that it would void my warranty . Has anyone had issues with red line oils in M6 smg or dif ?
