1999 Ford Taurus transmission

Have Have you checked to see if there are codes set in the computer? That would be my starting point. Also you have checked to make sure the alternator is charging the battery cable ends are clean and tight and battery tests good?

I also mentioned if your alternator is charging? Yes you would check for codes thats the first thing I would do if I had the car in front of me. Lean bank one nothing to do with the transmission. Sounds like you could have lost the transmission your drive axles didnt pop out one of them there in good shape? I would also check transmission pressure that requires a transmission pressure tester gauge set. You would be surprised what a loose corroded or even a bad battery does to a computer controlled car. Iam sorry you didnt like being asked to check some of the basics first. Dont want to say replace the transmission right off the bat you really wouldn't like hearing that even more right off the bat.

Thats really strange a bad selector switch didnt set codes especially since it was causing no gear engagement. There should be codes for a bad selector switch the code reader used must not have picked them up. The scanner I have reads all codes in all the computers in the car plus live data. Unfortunately not all the diyer code readers read all codes all the time.I have even seen some not even link to certain car brands and models. My first suggestion wouldn't have been a selector switch also iam not there to scan the car with my professional scan tool. Iam sorry you feel that way about our site. We set out to help people with there car problems unfortunately I cant share my tools scan tools etc with you and others on here. Its harder then it looks to help people fix there cars over the Internet.
