LIGHT TRUCK:
1997 EXPEDITION, F-150

ISSUE:

Soft/drawn out and/or slip/bump 1-2 upshifts may occur on some vehicles. This may be caused by the E4OD transmission being built with the wrong valve body separator plate.

ACTION:

Confirm the vehicle build dates are from 4/18/97 through 4/21/97, and transmission build date is 7D15 with serial numbers between 00012500 and 00012855. When confirmation is made, replace transmission with an exchange unit, or if exchange is not available replace the Separator Plate and mating gaskets. Refer to the following Service Procedure for details.

SERVICE PROCEDURE

  1. Verify the following:
    • Concern
    • Vehicle application
    • Vehicle build dates
    • Transmission build date
    • Transmission serial number
  2. Call (800) 543-8742 to exchange transmission.
  3. If an exchange unit is not available and vehicle fits the description listed in Step 1, replace the separator plate and mating gaskets.
    1. Remove transmission pan, main controls, accumulator body, and solenoid body.
