OK. I went out to my garage and got two quart bottles of CC Hydraulic/Transmission Fluid - one with the red stripe, part number 737-3025 and one with the old red and white Cub Cadet label that says Hydraulic/Transmission Fluid. Neither say hy-tran anywhere but both have the same part number - 737-3025. Now it seems to me the last time I changed fluid I bought gallons and it DID say Hy-Tran on the container. So, is this the HOLY STUFF? Part number 737-3025??? I'm not putting anything in this cub but the real thing but I'm not sure the girl at the parts counter is really that up to speed, etc.
