However Redline does offer 2 different fluids for manual cars.

Redline MTL (viscosity 75w80 - equivalent to motor oil that is 5w30) and Redline MT90 (viscosity 75w90 - equivalent to motor oil that is 15w40) and I think the thicker oil at 100 degree Celsius is the trick to getting the noise down when the transmission is hot. And according to Redline the MT90 does eliminate notchy shifting even when cold.

I can’t remember is I used MT90 or MTL earlier but it was quite bad at colder weather conditions.

MTL has been fine for me in colder conditions in the ZHP. I can't speak for MT90 since I haven't used it in my trans

I’m going to order some MT-90 and see if it helps. I’m currently running D4ATF.

I'm running Amsoil MTL. It acts up in the winter when it gets really cold, but not enough for me to switch it out.

Vas I sent an email to Redline about fluids. I explained I’m using D4 and asked about higher viscosity fluids to help with gear noise. I specifically mentioned how UUC recommends a blend of 1 quart 75W140NS and top off with D4 to help with chatter with UUC lightweight clutch/flywheels, asked if it was a safe combination, and to see what recommendations they may have as an alternate to D4ATF. This was the response I received...

I’m going to see if I can find some MT-85 locally.

There you go... direct from the mfr. Supports what everyone is experiencing with thicker oils... thanks for posting

Are you still using the BMW trans fluid? If you are how is your experience with it especially since you lived in NJ.

I ran pure D4 ATF and right after the new clutch, I drained it and did the mixture that Redline mentions above. 1 Bottle of Redline D4 ATF and 1 Bottle of Redline 75w140NS. And I still think the viscosity is too thin.

Curious to what they would say if you mention to them that the BMW Genuine GL4 fluid is a 75w90 viscosity ( Same as the MT-90 )

No issues that I remember with the BMW trans fluid either in NJ or here in SC. My first change was at 80K. I was starting to get a little gear whine. After the change it went away. I changed again at IDK... 130k? I guess I'm lucky that my wife, since moving from Ohio, has always worked for BMW or a dealer group that included BMW

2005 ZHP:

Year Start: 167,459

Year End: 179,702

Total Miles Driven in 2018: 12,243

Starting off the year with a new Autocraft Platinum AGM battery. Out the door cost was $153.99. Old battery was still starting the car fine but it was a 04/12 production date. Proactive replacement but did not want to get stranded if it did fail.

Car is also back on it's winter wheel setup. Spring will require a new full set of tires.

Happy 2019 everyone
