For what it's worth, I have been running Redline MTL in my 5-speed since I installed it in my 300TD. It's been about 10K miles and it shifts smoothly and there have been no leaks or other issues.

That's only 10K miles, admittedly, but I feel pretty secure with it since I've used Redline MTL for hundreds of thousands of miles in other period Getrag manual transmissions in BMWs over the years. Never had one fail on me yet.
