Lots of people seem to like Red Line. I'm not an expert on this, so any other comments?

I have experimented with several. The stock Mercon V, Valvolene Synthetic Mercon V, GM ATF, and finally GM Synchromesh. Without question, GM Synchromesh was the best shifting fluid. Mercon V was 2nd. And GM ATF 3rd. The worst one was Valvolene. Too slippery for the T-45. Watch out for synthetics in your trany for this reason.

GM Synchromesh without question. Yeah, it's $8.00 a quart, but it's worth it. I used it in my '88 LX 5.0 for 136,000 miles, and I've got it in my T-45 in the Cobra now.

The part # is 12345349, and you can get it from any GM car dealer.

The one thing i've heard most over the years is to stay away from synthetics!
Thanx for the help everybody!
