I thought we had decided that the John Deere HyGard was the hot ticket for 2 and 3 speed race transmissions. My trans and converter builder strongly suggests to never use the hydraulic/tractor fluid. Only exception is to use it for a test if you think you need a tighter converter. I've used Type F in my 727s for years w/ good results.
