Type of Fluid???

Type-F is recommeded in a shift kit. stock or oem oil was the dextron type--- Type -F is a more course type of fliud, dextron type is a more smoother fluid. I have used type-f in mine (727) since i have had the car (1992) They want you to use type-f with preformance upgrades(shift kits, stall converters, tranz-brake ect.)so the clutchs "grap harder" and helping firm up the shifts.
