Hi - most likely there is a problem in the valve body with this hydraulic circuit. The P0750 shift solenoid message, while accurate relative to which circuit is involved, may have only been the symptom, not the cause. A sticking piston in the valve body may be the cause. I would recommend taking your truck to a reputable transmission shop for a thorough diagnosis of the transmission for this issue.
