New to the Forum, which was recommended by an established member at Putnam Motorsports Park on Father's Day, Thanks David! I need to replace the fluid in my '18 10R80 GT PP. I've got about 13K on the car and 5 track days on the OEM fluid and it is shot. I see Redline and Royal Purple Max ATF discussed on another site, but they aren't weekend track warriors. I drive the car very little on the street, can someone recommend a fluid that stands up well to track day abuse?

Appreciate the help!

Can you help this fellow out @flyhalf?

Flyhalf has a ton of experience with this trans on a road course.

Use OEM FLUID.
our has a ultra low viscosity
Compare to many which are low viscosity.
I reccomend change trans fluid every 4 events.
And never ever pass 230f in temps otherwise you risk your tranny.

Hope this help

Could you also tell me about running the Sparco Alpha's in your '18. Do you have a contact airway light on the dash or did you remedy that so how when you swapped out your OEM seats?
