Hi, my name is\*\*\*\*\* to justanswer. Lets see if we can get you rolling again.
Code **P0756** means that the vehicle's PCM sensed **an** irregularity in shift solenoid B, which is located in the [transmission](/topics-transmission-ford/). ... These solenoids determine gear ratio based on [engine](/topics-engine-ford/) load, throttle position, vehicle speed and engine speed. Have you noticed any issues with transmission performance?

First thing I would do is check the trans fluid level and go from there. Has the trans been serviced lately?

Causes for this P0756 transmission code may include: Insufficient fluid level, Dirty or contaminated fluid, Dirty or clogged transmission filter, Defective transmission valve body, Restricted hydraulic passages, Transmission has internal failure, Faulty shift solenoid, Corroded or damaged connector, Faulty or damaged wiring Faulty PCM.
Start with the simple stuff. I would recommend a transmission service and go from there.
