No, it doesn't really make a difference.

2C3Z-7C522-CA was the part number for the complete hydraulic system last time I bought it (01/17/04). Listed for 131.10

I finally got around to changing this today..Man!!! what a difference!!! That was my problem. I would definetly recommend getting the master cylinder rod and plastic clip at the same time. My plastic clip broke upon removal and the metal push rod is a pita to get out of the old one. OBTW the switch assy slides towards the rear of the truck to remove. (the white piece).

Changing the hydraulics was my last resort before I bought a new tranny clutch etc etc...This place rocks!!!!The price we pay to be a supporter is nothing compared what I would have spent so far on this truck.
