I have a 2005 GP that was a base model. Now i have since did a swap to the l32 and ever since i put the engine in and the pcm in (overkill) i have had the code P2761. I don't notice any problems with the tranny itself except that the traction control light on the dash is always on and it doesn't work and the check engine light is on. I know the sensor is inside the tranny....how hard is it to change? I need to get this fixed so i can get my check engine light off for inspection. TIA
