Red Line in your MN6?
I have been reading some recent comments indicating that Red Line causes seal swelling and ends up making it difficult to shift. Has anyone experienced this or other unusual problems after changing the OEM fluid?

I switched my diff. to redline about 50k miles ago and no adverse effects that I know of. of course, my rear axle seal and o-ring are leaking now but that's par for the course with c5's.

Re: Red Line in your MN6? (jojog)
I am not going to knock Redline products because I have never used them but I will tell you I have read allot of threads on comparisons between Redline,Amsoil and Mobile 1 Synthetic ATF. What I have gathered from all the crosstalk is Redline is not certified. Chevy recommends Mobile 1 in my engine and is certifed SAE or whatever so I can't see taking any unnessisary risks with my baby I paid a ton of money for and continue to poor more into mods so I would go for protecting my investment. I have noticed considerable shift improvement since I changed to Mobile 1 ATF so I'm happy and I feel good about having it in the car and will soon change the rear end fluid to Mobile Synthetic so I'll run it exclusively throughout the car. Should have my Hurst shifter installed tomarrow and look forward to even better shifting. Just my 2 cents! :yesnod: :cheers:

I had the Redline in my Z06 (M12) for about 2500 miles. Pulled it out to go to Mobile one and sent the Redline to get checked out. To my surprise the report stated heavy insoluables in the oil. They recommended changing the fluid out and asked if the tranny had been hot (it had not).
In defense of the Redline the tranny might have still been breaking in as the Redline went in at 1500 miles. Of course the factory fill only had 1500 on it and the report never mentioned that the original oil was spent so the jury is out on that one.
Mobile one shifts as well or better, is recommended by Tremec, and quieted the "marbles" sound a bit. My vote is to use the Mobile one first and see what you think.

I have about 8,000 on my Redline - I have noticed no adverse conditions. Do any of these comments make you other Redline users consider changing to the Mobil fluid? Thanks - :thumbs:
