4.6L and 6R60 Transmission Equipped Vehicles Only - Bump While Braking - Various Transmission Shift Quality Symptoms

FORD: 2006-2008 Explorer, 2007-2008 Explorer Sport Trac MERCURY: 2006-2008 Mountaineer

ISSUE

Some 2006-2008 Explorer 4dr, Mountaineer and 2007-2008 Explorer Sport Trac vehicles equipped with a 4.6L engine, 6R60 transmission and built prior to 11/28/2007 may exhibit a bump feeling while braking to a stop less than 10 MPH (16 Km/h). Some 2006 Explorer, Mountaineer and 2007 Sport Trac vehicles built prior to 05/4/2006 may exhibit the following symptoms:

• Delayed engagements into Drive from Park, Neutral or Reverse.

• Hesitation upon tip-in after braking to a stop.

This TSB will diminish the incidence of the bump while braking at a stop and reduce tip-in hesitation while accelerating from a stop and improves the delayed engagements.

ACTION

Follow the Service Procedure steps to reprogram the transmission control module (TCM) and the powertrain control module (PCM).

SERVICE PROCEDURE

1. Install IDS/PDS or equivalent and ID the vehicle. 

2. Update the PCM and TCM calibration using IDS release 52.8 and higher or 53.1 and higher. This new calibration is not included in the VCM 2007.11 DVD. Calibration files may also be obtained at www.——-.com. Since the TCM cannot be independently reprogrammed, reprogram the PCM to ensure that engine and transmission calibrations are updated to the latest level simultaneously. ... Download File PDF
