As for the transmission, I do mine about every 20K miles. It costs <$100 in fluid for Redline MT-85, so I figure why wait. A lot of people go 50K miles or more.

Excellent advice here...

My clutch kit from Zspeed came with the Motul "Gear 300" 75w90 fluid. Has anyone used this stuff (in the tranny) and did you find it to be an improvement?

I hesitate to put it in as someone who posted here (see below) said the fluid became "gummy". (I find it a little hard to believe). I would like to hear of personal experiences using this stuff.

Clutch flywheel combo?
"From about 2 months I upgraded my clutch to South Bend Stage II Daily combo + Silent Disk + ZSpeed CSC + Motul Gear300.

Two note:
After 1400Km, I must return to the Stock Nissan Trans Oil (75W85 GL4), the Motul at first was good, but after some Km starting to be "gummy". In some UK forums, suggests also to buy Moly Slip additive. I bought also this, but the effect (at now) is very impercettible...."
