4R100 [98-UP] Automatic Transmission Pump Assembly (Non-pwm) (Cast RFF8)

Heat distorts a steel plate long before it discolors, which is why a pack that looks reusable often is not.

4R100 (Non-PWM) (Cast RFF8) (12 Bolt) (Less Valves) (Uses A Stamped Steel Coast Clutch Drum). This steel set is manufactured to the thickness and flatness the clutch pack requires, so the frictions seat against a true surface.

Parallel faces are what keep the apply load off the edges of the discs. Shipping weight is 8 lb.
