So when i've been pressing park, every now and then there's been a bit of hesitation before it engages. Today this started showing up. Traction light on because I had turned off traction assist.

I press P it goes to N and the warning appears. If I cycle it to R and D it will go to P after a few tries. My driveway has a slight tilt and I just killed the engine in N and when I let my foot off the brake it didn't roll. When I started it back up it was still in neutral.

I've pulled the console and reseated the switch but no change.

Thoughts?

 

These ss transmissions are terrific until something goes wrong (smile) It almost seems that the fluid pressure that actuates the shift into park might be the problem, not the switches themselves?
You might want to post this on pistonheads as there seem to be a lot of ss cars there.

 

Thanks - Will do.

 

Since you have the automatic DB9... it could be a few different things. I would first check the parking release under the drivers side rear seat and cable where it attaches to the transmission. Has the car been towed lately? If that stuff checks out, I would investigate the functionality of the switches. There is a bulletin to overlay a harness for the switches if they are operating ok. If you want me to check it out, let me know; I'm in Oakland. -Tim
