We ran RedLine D4 ATF in all of the race cars using T56 and similar transmissions.
If you are using the car in extreme conditions and heat, you can mix in one bottle of gear oil to three parts of D4. Running straight gear oil is much to thick for the transmission.
This is a tip that I got from Tim Kerrigan, owner of RedLine Motoroil and avid Corvette enthusiast.
