to C'Fans.

It would help if we knew what model year and what engine you have.

P0787: 3-2 shift solenoid control circuit low voltage.

Could be a defective solenoid (located inside the transmission), a wiring problem, or (rarely) a defective TCM or PCM depending on the year of your truck.

Check the wiring/connectors for the transmission. Look for a round 20 pin connector. Some guys have had problems cause by rodents chewing on the wiring.
