Anyone still using ATF in their 5 speed?

I switched to Redline MTL about a year ago and find that shifting is worse in the cold than with the ATF. It's fine after 30 minutes of driving. Is ATF thinner? Anyone using ATF or know if it is safe for the transmission?

Thanks, Dave

ATF is "safe" but it will wear the synchros faster. ATF is thinner.

I noticed the slow shifting when cold but it was not for 30 minutes, maybe 5.
