"Trick Shift" is the brand name for B&M's automatic transmission fluid. It's been around for some years and is used by quite a few Ultramatic and Twin Ultramatic users. It's been suggested that its additive package may contain a rosin-type component to give it the "stickiness" that is claimed to be it's advantage over conventional fluids. From my own experience with it, it can provide temporary relief for groaning direct drive clutch engagement.
