Transmission Oil

Need help on selecting manual transmission oil. Here are some things I have to consider, I try to drive my Corvette as much as I can but in cold weather (I live in the Niagara Falls NY area) I notice "stiff" shifts even after letting the engine run. When I drive it, I do get "into" all the power the car has to offer. So I'm looking for temperature "correctness" and protection for all types of driving. Any ideas?
Thanks. Andy

PS. I plan to change the oil myself.

Most people ignore transmission fluids. Even worse most people only talk about the importance of flushing an automatic transmission.

I use the factory fill. Regardless, something to keep in mind is that the rear-mounted transmission gets no significant warm-up from the engine heat - the only way to get a C6 transmission warmed up is to drive it. If it's cold, it will take even longer.

I switched to ams oil last week, it seemed to have helped the notchy-ness when its cold a lot.

Royal Purple Syncromax, many of us here on this forum have had good results with it.

I changed out my early '05 MN6 with Redline earlier this year, and I found no difference with anything!

I changed to Redline D4-ATF in my 01Z06 and to AMSOIL ATF in the current 06Z06. Neither change had any significant effect on shift feel that I could really claim. Still happy I made the change if nothing else to get a superior synthetic fluid in the tranny.
