Trouble codes: P0500, P0700, P0963, P0967. My vehicle has driveability issues. There are no noticeable smells or strange noises. When it's engaged in reverse it drives fine. When I shift to drive it accelerates slowly. If I keep accelerating the vehicle can exceed speeds of 50mph. In any gear the transmission is engaged(D, R, I, 2) the engine RPMs stay around 2k when the accelerator pedal is floored. In park and neutral, RPMs go to around 6k(or 4k... don't remember which) when the pedal is floored. The vehicle will otherwise start and run fine. It's is a 2002 Saturn Vue with a 3.0L V6 motor and AWD drivetrain. What are the possible causes of these symptoms?

Thank you for writing in. The codes you have pertain to the transmission and its various sensors. 

P0500- Vehcle speed sensor (may be the cause of everything else)

P0700- Defect in transmission control circuits (likely caused by the next two codes)

P0963- Pressure control circuit A

P0967- Pressure control circuit B

The symptoms you describe also back up the troubleshooting codes, in that the transmission is struggling to manage hydraulic fluid pressures correctly. These issues result in shifting problems, lack of acceleration, and a general loss of power. You will likely need to replace the vehicle speed sensor, which can be tested by a technician. Issues with these sensors result in the transmission struggling to find the electrical information it needs from the given sensors to respond to what the driver is doing.  

Good luck!
