Mainly in the cold but sometimes in warm weather. My parents 2004 Pontiac Sunfire will not shift out of park. Is there a switch in the brake pedal or something that prevents this? If I leave it in neutral it shifts fine, just cant always get it out of park. Neutral is dangerous and not a real fix. Tx.
The switch go in too the brake pedal Maybe has Little shorts or the cables connect to the shift mechanism on the top of the transmission. The cable or the linkage may have broken
Automatic Transmission Shift Lock Control Description and Operation
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of thew following components:
• The automatic transmission shift lock control solenoid
• The body control module (BCM)
• The powertrain control module (PCM)
With the ignition in the ON position, battery positive voltage is supplied to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid receives a ground from the BCM. When the automatic transmission shift lock control solenoid is energized, the shift lever mechanically locked in the PARK position. When the driver presses the brake pedal the PCM sends a class 2 serial data message to the BCM. The BCM turns OFF the ground control circuit and this de-energizes the automatic transmission shift lock control solenoid. When the automatic transmission shift lock control solenoid is de-energized, the shift lever may be moved out of the PARK position. The BCM determines transaxle shift lever position through a class 2 serial data message from the PCM. The PCM receives inputs from the park/neutral position switch and determines shift lever position. When the BCM receives this information and determines that the shift lever is out of the PARK position, the automatic transmission shift lock control solenoid ground is opened.
Do you know what a DTC is ? Diagnostic trouble code !
DTC B2708
The body control module (BCM) controls the automatic transmission shift lock control solenoid. Positive voltage is supplied via the ignition 1 voltage circuit to the automatic transmission shift lock control solenoid. The BCM controls the ground circuit of the automatic transmission shift lock control solenoid . When the brake pedal is depressed, the BCM removes the ground allowing the solenoid to disengage. This action allows the vehicle to be shifted out of the PARK position.
Conditions for Running the DTC
DTC B2707
Your best bet mite be to have a qualified repair shop check it .
SOURCE: Will Not Shift out of Park
Do you have your foot on the brake when shifting? Some cars will only shift when brake is fully depressed. Good luck
SOURCE: 97 pontiac sunfire convertible, stuck in neutral
could be just fuse,brake switch or shiffter lock in position
SOURCE: Pontiac sunfire istopped and in
check shift cable under hood. it may be broken !! to transmission.
