What size engine? 5.4L (early 2010) or 6.2L (later 2010 1/2)

First, can you tell us what error codes are showing up with a OBDII scanner.

Have you checked speed sensors at the wheels?

There is an input and output speed sensor for the transmission.

Check the wires from the PCM to the Transmission,

that wire harness does come loose with age and gets melted by the exhaust manifold.
