Not pleased with MTL in 540i/6. Other recommendations?

[DueyT]

I changed my 6-sp's fluid back in the fall to Redline MTL. At first shifting seemed to improve. Then it started to get notchy, in particular 2nd gear. In the cold weather (especially this -25c stuff we had in Southern Ontario recently) the notchiness was particularly bad.

What are other manual trans guys using? I was thinking of either trying Redline D4ATF or Mobil Synthetic ATF? Any other suggestions?

Cheers!

not sure how mtl does in the later cars, it works wonders in a e30, rebuild in a can

Over the summer, I switched from MTL to Mobil 1 ATF. This winter, the cold shifting is MUCH smoother than it was last winter with MTL. Folks on the E34 M5 mailing list also recommend adding a few spoonfuls of molybdenum sulfide powder to the trans fluid.

MTL in cold weather

Thanks gents. I don't have a problem changing fluids and see what works best. I'll go for Mobil 1 ATF at first, as it's a bit more avail than Redline.

Cheers!

A lot of older MR2 owners swear by it (notoriously difficult shifting car due to synchro wear and very funky shift linkage).
Redline also makes lighter synth gear oils than MTL...

I swapped out both tranny and PS fluid in my 525i for Mobil1 Synthetic ATF.
Here in the sunny Midwest the GQ starts up and runs just fine in VERY low temps....
