Unusually firm or harsh and/or delayed shifts may be experienced on some of the subject vehicles.

Light trucks, vans and Broncos with the 5.0L EFI engine and the AOD transmission may have TV pressure set near or above the TV pressure specification of 35 psi and experience harsh and/or delayed shifts. It has been determined that on a customer concern basis, the TV pressure may be set lower to eliminate the concerns without affecting the transmission durability.

Following the procedure (TV Control Pressure Check and Adjustment Procedure with Engine ON) detailed in Section 17-20 of the Light Truck Shop Manual, reset the TV pressure to 29 psi with the shift selector in Neutral. This will result in a TV pressure of approximately 31 psi when the shift selector is moved to a forward gear ((D) or D). This is 4 psi lower than the 35 psi previously specified as being optimum in a forward gear.

IMPORTANT
This procedure applies ONLY to Light Trucks, Vans, and Broncos equipped with 5.0L EFI engines.
