I just bought 03 LS6. When the ignition is switched off, the driver's seat automatically moves to the back of its track. My friends always get stuck in the back seat. I need the power seat, but just don't want it to move every time the ignition is off. I guess the moter is not cheap to replace. I can't afford to buy a new moter every year. Also, the last owner didn't replace the transmission, so I might need to fix the transmission soon. My LS has almost 100k mi. Has anyone replaced new transmission for 03-05 LS6? How much did it cost? Does anyone know how to stop the seat?
