Service bulletins for the 2014 Ram 2500

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

All 3.6L/62TE equipped vehicles. If the vehicle you are repairing has a crack in the flex plate or failed pump bushing inspect and confirm that both (2) dowel pins are present in the engine block, which align the transmission center line to the crank shaft centerline and visually inspect the dowel alignment holes in the transmission case. If the holes are damaged or elongated the transmission should be replaced to prevent further damage to the transmission/flexplate or pump bushing due to the inability to properly align the engine to the transmission during the repair. 3. All 62TE equipped vehicles. If pump bushing is scored or damaged and the dowel pin alignment holes are ok, replace the pump assembly as opposed to complete transmission. 4. All 62TE equipped vehicles. If vehicle is jerking/slipping with MIL code(s) P0740 or P2764, check TCC Solenoid operation. If TCC Solenoid is ok, the codes are indicative of a torque converter failure. Replace the torque converter.

5RR541XRA2022-08-22. Service bulletin. POWER TRAIN; VISIBILITY; PARKING BRAKE. Power Fold Rearview Mirror Prior to replacing this part for a loose mirror, please first follow this procedure to reset the pivot mechanism. Move the mirror to its full forward position and then to full retract position using the power fold mirror button located on drivers side door panel. Perform this procedure three times. If this doesn't resolve the issue, then repair as necessary.~ Note: 1- The looseness of power fold mirror does not necessary indicate a defective mirror, it may be caused by folding it manually rather than using the power fold feature. If the mirror is adjusted manually out of the proper detent, always use the button to adjust it back into sync.~ 2- The intended use of the power fold mirrors is by pushing the button to fold and unfold the mirror. Only manually fold the mirrors when absolutely necessary.~ 3- In the circumstance where the left hand mirror and right hand mirror are in different positions, it may take up to three cycles (bottom pushes) to re-sync the mirrors together.
