I have a problem with the shift lock not working at times. The dealer replaced the shifter assembly but problem still happens. The problem happens from any time, it seams to happen more if on a slight slope or shortly after going over a driveway entrance and then parking and when I return I cannot get the shifter out of park and I hear no click from the shifter area when I step on the brake. The dealer has checked out the system one time since they replaced the shifter assemble. since I got the TB back from the last time the problem has happend 5 times in the last two weeks. Has any one else had this problem and if so has it been repaired?
