Hiya linas-welcome to the group!
I guess yours must be the "other SVT" Steve at Campbells mentioned this morning when we talked on the 'phone. (I saw it there last Friday)
I'm really starting to get frustrated with this dealership: First visit, car returns with one of the sideskirts half off the car, grease all over the inside of the front door panels, and both right side tires looking like they'd been rubbed against a curb.
Next visit, they fix the sideskirts, but add some transmission fluid all over the console to go with the grease on the doors, and disable the cigarette lighter for good measure.
Like you, my new tranny is as bad, if not worse than the original. Since the tranny replacement, the car has also developed this weird kind of creaking and snapping in the front end when I start off in first...like something in the drivetrain has way too much "play" in it.
This Steve guys says they're still trying to get some info from Ford engineers in Dearborn.
Good luck to both of us.
