My 2003 Oldsmobile altero gets stuck and i have to jiggle the shifter or leave it set for a min befor if will go from park to reverse ect.. Just got the car yesterday


Your problem is more then likely with the Automatic Transmission Shift Lock Control .This is a safety thing . Has a switch , wiring and a electrical solenoid .
Automatic Transmission Shift Lock Control System
The automatic transmission shift lock control is a safety device that prevents an inadvertent shift out of PARK when the ignition is ON. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
• The automatic transmission shift lock control solenoid
• The automatic transmission shift lock control switch
• The park/neutral position switch

Sorry to here your having a problem with it already .
There are diagnostic step to find the problem , involves using a DVOM - digital volt ohm meter an using a wiring diagram to locate test points in the circuit . Plus you will need to take parts of your vehicle apart to get to those test points . The most likely part to fail is the park neutral safety switch . The contacts wear inside after hundreds of times of moving the shifter . But without testing this is just a guess .

With the ignition in the ON position, battery positive voltage is supplied to the park/neutral position switch. With the transmission in the PARK position, the contacts in the park/neutral position switch are closed. This allows current to flow through the switch to the automatic transmission shift lock control switch. The circuit continues through the normally-closed switch to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid, mechanically locking the shift linkage in the PARK position. When the driver presses the brake pedal the contacts in the automatic transmission shift lock control switch open, de-energizing the automatic transmission shift lock control solenoid. This allows the shift lever to move from the PARK position.
