Ford Five Hundred Transmission Shifter is Hard To Move
Ford Five Hundred Problem
Drive Trains Affected: AWD, FWD
Average Mileage: 72,633 mi (20,000 mi - 100,000 mi)
I had the same problem with the shifter not wanting to move. The black strip would bunch up and I'd not be able to get it to move. Took it to our local dealer. He sprayed it with silicone spray and then gave me the rest of the can in case it happened again. No problems since then. My dealer could have told me anything was wrong with the car, but he tried this first. I am very happy.

Gearshift binds up on the black strip making it extremely hard to get it into drive
The rubber strip around my shifter is bunching up, making it hard to put it in drive. Then, sometimes it comes out of drive when I'm going down the road.

Have had this problem since 10,000 miles or so. Thought it was just dirty/sticky, but cleaning it did no good.
