help! I have a 2003 mercury sable, had a slight oil leak but nothing major. Was on the way to work when my car started jerking like crazy, both the check engine and transmission light came one. The car also wont shift gears.

Fix per codes and check transmission operation. Now is the time to trade it in if you can afford the new payments.

I took it to a transmission specialist the Guy ran his machine and it popped up with 7 different electric codes. He said he wasn't sure what the problem was. I'm afraid to bring it back and have him check it out again. You give me no hope when you say take it back if I can afford new payments. Does it sound like an extremely expensive problem?

Don't go back to that guy! The transmission for your car cast about $1800 to $2000 to either replace or rebuild. Ford dealers have a 3 year warranty if you decide to buy a rebuilt. You could take your chances at a wrecking yard but changing out that tranny in the driveway is A LOT of work if it fails. My associate was referring to replacing the vehicle instead of fixing it. I would strongly weight the value and condition of the vehicle vs. buying another car.
