Default Synthetic fluid in 5-speed manual

I'm thinking about changing out the fluid in my 07 GT 5-speed manual and going with Royal Purple Syncromax or possibly Amsoil if they have one that will work. What kind of experience has anyone had with this change? Did it make a noticable difference in the shifting or reduce the transmission noise? I tried the search but it doesn't seem to show any results and I'm sure this must have been discussed before.

I have never used Redline but have heard good things about it. Do you have it in your Tranny?

I've heard good things in general about Royal Purple products but I wasn't sure about using it in a manual 5-speed. It may sound strange but I wondered if it could be 'too slippery' and cause issues with the synchronizers or something????? My gut says it should be an improvement but I'd like some sort of validation to that.

Been a believer in RedLine Products for years and several hundreds of thousands of miles, two cars and a PU.

Mustang GT, 5 speed, has RedLine D4 in it. Used a 10% mix of "Tufoil" from www.tufoil.com Tufoil originally recommended to me by the machinist that custom built a modified BMW engine for me. I truly believe it shifts better, smoother, still "notchy" and not like a BMW trans. Redline says the fluid good for 30 to 40k miles. I put in at 3.8k, now have 24k and change, plan to change at 30k.

Moved to NC, Redline only availablehere by mail order. Hassle. Found a local Amsoil dealer,25koil change will be Amsoil, trans change at 30k will be Amsoil, motorcycle and PU will follow when it is time, Tufoil is used in all rides.

I looked at the Tufoil web site but didn't see a tranny additive, only engine additives. Did you mix Tufoil with Red Line in the tranny? Which Red Line product did you use in the transmission?
