Hi Walter,

I would try a better quality shop to start with, and ALL your issues may be related to one thing, a bad computer.

A good shop will test all phases of the computer functions including the shift solenoids in the transmission.

I am attaching a doc for you to reset the security system too.

Thanks, Ron
