ISSUE:

Intermittent Transmission Control Indicator Lamp (TCIL) or Malfunction Indicator Lamp (MIL) illumination may occur on some vehicles. The following Diagnostic Trouble Codes (DTCs) may be stored in memory: P0741, P0750, P0755, and P1746. This may be caused by the solenoid interconnect molded lead frame not being fully seated or the bulkhead interconnect clips not being fully seated between the solenoid interconnect molded lead frame and bulkhead interconnect.

ACTION:

Verify the solenoid interconnect molded lead frame (-7G276-) is fully seated. If no concern is found, then inspect the bulkhead interconnect terminals for spread and/or not fully recessed. Refer to the following Service Procedure for details.

SERVICE PROCEDURE

  1. Perform normal diagnosis for DTCs retrieved as outlined in the appropriate 1999 Workshop Manual. If root cause is not determined, continue with this TSB.
  2. Remove the transmission oil pan per the appropriate model Workshop Manual, Section 307-01.
  3. Verify that the solenoid interconnect molded lead frame is fully seated on all the solenoid connectors (Figure 1). If the solenoid interconnect molded lead frame is fully seated, then gently remove the solenoid interconnect molded lead frame, valve body, and bulkhead interconnect (-7G276-) per the appropriate model Workshop Manual, Section 307-01.
  4. With the bulkhead interconnect removed, push down on the terminal cover and check to see if any of the terminals are slightly protruding above the plastic cover (Figure 2). Gently pry off the terminal cover using a small screwdriver (Figure 3). With the terminal cover off, inspect the bulkhead interconnect for spreading terminals (Figure 4). If the bulkhead interconnect terminals are spread or slightly protruding above the plastic cover, replace with a new Bulkhead Interconnect (F8AZ-7G276-AA).
  5. Reassemble.
