Hi Scotty! 

I have a 2010 Mazda 3 i Touring automatic transmission with 135k miles.  Was getting code U0101, jerking and near stalling.  Sent TCM to be repaired.  Sent it in 2x.  No luck!  Purchased a brand new Mazda TCM.  Received and installed new unit.  Hooked up to OBD scanner, and still getting code U0101.  What does this mean and what should be my next step?

Thank you!!

well start tracing all the wiring or pay a really good electronic mechanic who knows Mazda's inside out has wiring diagrams to find out where the short or sensor failure exists
