Redline D4 ATF in a manual trans?A long time ago. No seriously you need to change it ASAP and then every 30,000 miles (50,000kms). For blighty Redline D4ATF for g'box, RL 75W90 for diff, and RL D4ATF for p/s as used by most on BMW forums who change their fluids. You won't believe the difference it makes
Thanks sprintman :thumbsupYes of course the OEM oil is ATF as used in many manual trans. I have an email from Dave Granquist Redline tech who confirmed this should be used. I currently have Redline MTL in my trans but to thick for a Canberra winter let alone an English winter (I remember them well) so I'll be changing come autumn to a 50/50 blend of MTL and D4ATF. And no clutch fluid is brake fluid which is not the same as trans fluid.
