Good evening.

I'm sure some of you know about the E46 ZHP Owners facebook group: https://www.facebook.com/groups/bmwzhp/

I posted there today telling of my experience changing out my transmission fluid to Redline MTL 75w80. I previously put Pentosin MTF2 oil in my transmission (about 30k ago), and it has recently felt notchy and stiff.

After switching to Redline last night, I drove the car down the road about 1 mile and back. It feels incredible! The gears engage so smoothly, there is zero notchiness, and the car shifts better overall.

A few members of the facebook group are crying heresy, telling me to change out the fluid as quickly as possible because I've put the "wrong spec fluid in my car", and there "are far better fluids now than Redline MTF", etc.

When I made the decision to use Redline 75w80 MTL, I utilized these threads:

Can anyone tell me definitively if I've made a horrible mistake and indeed should drop the MTL out as soon as possible? Thanks guys.
