Transmission Flush

[chitowndad]

Guys,
I'm setting up my winter projects (doing the research now) and I want to flush the manual transmission on my 01S. I've seen a couple posts that were from 2005-2006 about using 3 qts of Redline MT90.

I once had a 1991 300ZX (loved that car) and I changed the transfluid on it several times. I started with Redline MT90, then Royal Purple and then a thinner weight Redline. Since my 300ZX had synchro issues (clucking in 2nd), the thinner Redline did the job... On the 300ZX the fill plug was on the top of the transmission and the drain was on the bottom, which was real easy to find.

Does anyone have a link to the manual transmission flush, specifically the drain and fill plugs?

Would you recommend 3 qts of the Redline MT90 for the Boxster?

My Boxster is 2001S with 11K mikes and has never had the transmission flushed. It's a little sticky shifting when the engine is cold but is ok when warm.

Any insight is appreciated.
