E4OD, 4R100

Symptoms:

• Burnt intermediate clutches
• Intermediate clutch failure
• Direct clutch failure
• 2-3 Slip
• 3-2 Slip
• No 2nd
• 1-2 Soft
• Delayed Reverse
• Direct clutch burned

Cause:
Clearance and movement between the case and center support allows apply fluid to leak, lowering clutch apply pressure.

Correction:
Sonnax intermediate and direct clutch feed seal kit prevents loss of critical apply fluid.

In Ford 4R100 and E4OD units, 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 Sonnax intermediate and direct clutch feed seal kit.

• Drop-in seal kit for both intermediate clutch and direct clutch feeds
• Seals even under heavy loads when movement/flexing of center supports occurs
• No special tools or machining required to install
