Q: W4A33 transmission oil for drag racing

[tristan1]

Hello

So i want to change the transmission oil but i need some advice.
I have in W4a33 transmission: IPT End clutch, translab shift kit, kiggly front clutches, kiggly flexplate, sinister 8" core 2 torque converter.
Before i had there Redline Racing ATF but in Europe the availability is difficult.
Car is used on tracks (drag racing), engine have ~500hp.
I think i need to get some low viscosity oil, because while line-upping i get higher oil temps then the RPMs goes more higher and i can start better (i dont have nitrous).

Many thanks!

DTR (Darren Thomas Racing), a builder of our auto transmissions, told me Dextron 3 and to not run synthetic in my unit I bought. I think the only way to contact him is through FB though.
