Gen V ACR best gearbox and differential oil for track use

[Maxi_ACR]

Any suggestions on some aftermarket gerbox oils to use on the Gen V ACR gearbox and differential oils for track use ?

For the Gearbox should ATF still be used or anything better from Redline or Amsoil or other brands ?

For the diff the best would be the Castrol Transmax 75w140 ?

I have used the recommended OEM ATF and differential fluid since the car was new, and have never had an issue. I do change the fluids often, however, including before every track day.

If you're tracking extended periods look at Doug Shelby Engineerings trans/diff cooler setup. ATF if cheap/easy to change. Classic Valvoline Dex/Merc is what many Tremec builders stick with. Others have gone to Redline or BG SynchroShift. Tremec also has their own HP MTF.

Tick Performance, still uses dexmerc.
