T56 Transmission Fluid

[BryanL]

Ran Redline D4 ATF for years following the recommendation of LAW Motorsports and never had any issue. I have switched to Motul Gear 300 75/90- D4 ATF along with Patterson I believe and also haven't had any issue that I'm aware of.
My thought is the T56 is overkill for our power levels and I don't think heat is an issue either so run a good fluid that can handle the heat. That's where I'm led to believe Motul does a good job of handling heat-I run Motul in engine, trans, and rear end.

I'm not one to talk, but that's only like four weekends on the fluid, right??

Yeah but he uses reverse way more than anyone else. Much harder on the fluid...

Just changed trans fluid using Redline D4, and it looked perfect after 7 seasons. Put Redline back in.
Ready for COTA.
Will have a new look.

I use Walmart Valvoline fluid. Replace it once a year as needed. Seems to do the trick.
