Traction control light. Transmission delayed shifting.

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! With the traction control light staying on and the delayed shifting in your 2011 F-350, it sounds like the steering angle sensor and brake switch codes might be clues. Both of these components can affect traction control and could be throwing off the truck’s stability systems, which might explain the higher RPM shifting. Start by addressing the codes—replacing or recalibrating the steering angle sensor and checking the brake switch. These fixes could get the traction control system back in line and may resolve the shifting issues as well.
