Pressure Regulating Solenoid: Technical Service Bulletins
A/T - Line Pressure Control Solenoid Service Information
BULLETIN NO.: 02-T-44
ISSUE DATE: June, 2002
CATEGORY TYPE: Transaxle - 05
CATEGORY: Automatic
CORPORATION NO.: 02-07-30-027
SUBJECT:
Service Information Regarding New Design Line Pressure Control Solenoids
MODELS AFFECTED:
2000 - 2003 Saturn L-Series Vehicles
PURPOSE:
The purpose of this bulletin is to provide service information about two different line pressure control solenoids used for service. When performing
service on an L-Series that requires line pressure control solenoid replacement, the correct solenoid must be used for the specific model year and
application. In 2000 - 2002 model year vehicles, the Delphi line pressure control solenoid is used and in 2003 model year vehicles the BOSCH line
pressure control solenoid is used.
NOTICE:
The line pressure control solenoids are not interchangeable. Both solenoids will physically fit in the valve body and will connect electrically,
therefore care must be taken to ensure the proper solenoid is used.
If the incorrect solenoid is installed, the shift characteristics of the transaxle will be affected without setting a diagnostic trouble code (DTC), If a
BOSCH line pressure control solenoid is installed in a 2000 - 2002 model year vehicle, the transaxle will shift hard and erratically without adapting.
Conversely, if a Delphi line pressure control solenoid is installed in a 2003 model year vehicle, the transaxle will have a soft, slipping feel that may result
in transaxle damage prior to adapting.
The Delphi solenoid (1) can be identified by the part number and Julian date stamped on the back of the solenoid body. The BOSCH solenoid (2) can be
identified by the name BOSCH molded in the plastic near the electrical connector. Refer to illustration shown to determine which solenoid is being used.
IMPORTANT:
When diagnosing a line pressure control solenoid, refer to the applicable model year Saturn L-Series Transaxle Service Manual for correct
diagnostics and pressure versus amps chart. Do not use the previous year's pressure versus amps chart for the Delphi line pressure control solenoid
