i have a 1971 911S (5-speed). i'd like to change the tranny fluid to the redline synth stuff since i had such good luck with it in my old saab.

just two problems: i'm not sure where the drain and filler are.

my guess is they are the 2 hex bolts on the left side of the tranny. drain on the bottom & fill on top? if so do i have to pump it up into the top hole? how do i check the level?

thanks.
