Ok, have the computer scanned. Advance and Autozone auto parts stores will do it for free. Post the trouble codes and we can help further. Sounds like a transmission solenoid problem but get the codes to be sure. Thank you for the best answer click as well. HTH. -Jim

there were 4 codes P0341, P0715, P0740, P0700

P0341 is camshaft position sensor circuit, P0715 is transmission speed sensor circuit malfunction, P0740 is torque converter clutch circuit malfunction, and P0700 is transmission control system malfunction. The camshaft position sensor and crankshaft position sensor are common trouble spots on these cars. As for the transmission codes try unplugging the large wiring connector going to the transmission. Inspect the plug and the socket it plugs into. Clean up any corrosion and look for any damage. Clean it up real good then plug it back in. Sometimes by doing this it will straighten it out. If not you'll need to take it to a transmission shop. If you decide to replace the camshaft position sensor replace the crankshaft position sensor as well. The two sensors work together. If one fails the other is usually soon to follow. HTH. -Jim

I ran the codes on my 2002 Pontiac Grand Prix. P0306, P0753, P1810, P1860, P1404, P1860. Can you help me understand these codes?

P0306 is misfire cylinder number 6, P0753 is shift solenoid A/B electrical (transmission), P1810 is transmission pressure switch manifold fault, P1860 is TCC PWM solenoid fault (transmission), P1404 is EGR valve closed position performance (may cause rough idle and/ or stalling). Honestly, at this point I'd say you need a new transmission. HTH. -Jim
