Hi,
The code is related to the governor pressure sensor. Do you have a different code related to temperature?
If you look below, I included the diagnostics for the pressure sensor. Since the transmission was just replaced, I would start by checking the connections at the transmission. There could be a resistance issue in the connector. Or the overhauler installed a faulty sensor or there is a mechanical issue within the valve body. Basically, the pressure sensor is sensing more than 3 psi when it should be 0.
Take a look through the diagnostics below.
Let me know.
Take care,
Joe
See pics below. Note: At this point, I would contact the remanufacturer to see what they tell you.
