As I posted in a previous post. My service engine soon light came on after picking it up from the dealership for some other problem. They told me i either needed to replace the torque converter or the transmission and recommended the transmission because replacing the torque converter doesn't gaurantee to fix the problem.. mind you the cost is $8000. The nice people on there recommended i get a second opinion and not at a dealership.I don't trust them anymore, it seems like whenever I take it in for something no matter how minor I have 6 other problems that pop up right after they fixed what ever I had it in there for. Sorry to hear what's going on with yours.. I wasn't any help but I understand the frustration.
