Clearance and movement between the case and center support allows apply fluid to leak, lowering clutch apply pressure.
Install the Clutch Feed Seals during rebuild to prevent loss of critical apply fluid.
A major cause of low clutch apply pressure, soft shifts and burned clutches is leakage between the case and the clutch feed passages in the intermediate clutch support and the center supports. There is no positive seal as oil passes from the case to either of these supports, and normal clearance, accumulated wear and movement of the supports under load combine to cause major leaks at this location. For a 100% positive seal and zero leakage, install the 36424-24K seal kits into every overhaul.
