I confirmed to MOTUL Japan. And I received answer.

Q1. Does Gear 300 attack to the seal form by ester?
A1. Because your car is 2004 model,Probably no problem.

Q2. Does Gear 300 attack to the steel synchronizer by additive?
A2. No problem.

Q3. Does Gear 300 include the friction modifier for LSD?
A3. No.

Gear 300 has best temperature characteristic and does not include the friction modifier. I will try it next time. :-)

we used 3 bottles. 1500 miles later the car feels great.

I guess Motul 75W140 include the friction modifier. Doesn't a Synchronizer slip?

Just to throw another option out there. I run Syngear II 75-140 hard to find but really stands up to heat well.

Just did a track day at Mid-Ohio using Amsoil Severe Gear 75w110...It is by far the best shifting fluid I have run in the 964 cup...LSD was fine and chatter was minimal, as it was with Delvac and Redline fluids...I'll be using it for the next two events and see how things progress but i must say that after over 75 laps today it really shifts nicely.

P.J.S.

That's what I use and it is great

Just changed my transaxle fluid today using Delvac. This is a dirty, smelly job my friends. My Mityvac worked like crap pumping the oil into the gear case. Ended up using a hand pump which worked better. Plan on throwing out your clothes after this one Going to Sebring next weekend so I'll have a chance to test it soon. Also put on Fabspeed cat bypass to go with Fabspeed headers and mufflers. Sounds sick when rpms rise

Just noticed this at Suncoast. Is this the factory fill in 1L containers?

Yes.
At my local Porsche center they tell me it only comes in 1L or 20L. They sell me the 4L required for a oilchange by pouring oil from their own 20L over to a clean and empty 4L container.

do GT3 gearboxes have oil cooler?

ninerguru

Yes, they do... It uses a heat exchanger to circulate engine coolant and cool tranny oil. System is controlled by ECU allowing coolant to flow into heat exchanger based on trans & coolant temp. Trans also has an oil pump that sprays working surfaces of gears and also splashes ring gear for cooling.

You can't. They only sell it by the drum.
