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.
