This TSB is being republished in its entirety to correct the transmission build dates.

ISSUE:




Some E4OD transmissions with build dates between 5803 (February 3, 1995) and 5E31 (May 31, 1995) may have a valve, in the pump, that restricts fluid flow (Figure 1). This valve may become stuck in the valve bore and restrict lubrication. Symptoms may include heat distress on the overdrive planetary gearset, coast clutch cylinder bushing and/or overdrive cylinder bushing.

ACTION:
During overhaul of E4OD transmissions with build dates 5B03 and 5E31, inspect the components listed above for signs of heat distress. Replace the valve assembly using a service valve kit (E9TQ-7H132-B) which should resolve the issue. Refer to the Instruction Sheet included in the kit for details.

The Valve Kit includes the following:

^ One (1) Orifice Cup Plug
^ One (1) Spring and Stop Assembly
^ One (1) Instruction Sheet (I.S. # 6574)
