P215C: 845RE output-speed correlation and application-specific updates
P215C in this bulletin concerns agreement between transmission output-shaft speed and wheel-speed information.
Read before applying this article
Documented application
Chrysler/FCA 21-004-15 addresses 2014 vehicles with the 845RE DFL transmission. P215C is explicitly listed for 3.6 L ERB AWD LD/LX vehicles and in the DS section.
The code alone does not identify a failed part or establish that a vehicle is safe to drive. Confirm the vehicle, reporting module and applicable service procedure.
Correlation compares two observations
P215C in this bulletin concerns agreement between transmission output-shaft speed and wheel-speed information. The source identifies a software correction for the specified all-wheel-drive applications. That finding does not, by itself, prove that the output sensor or a wheel sensor has failed; the controller’s comparison logic is part of the documented case.
The model table is not blanket coverage
The release includes several 2014 models and engines, but its improvements are divided by application. For example, some sections address only harsh downshifts or ECO-mode memory. The P215C entry should follow its own 3.6 L and drivetrain qualifications rather than being assigned to every vehicle appearing on the first page. Confirm the transmission sales code and the relevant model subsection before choosing a repair.
Learning conditions matter
The repair does more than install transmission software: it includes a prescribed module-sleep stage and subsequent transmission learning preparation. The document specifies a minimum fluid temperature for that process and vehicle-operation conditions that belong in a controlled workshop procedure. A cold, stationary code clear is not equivalent verification. Record the software level, completion of the applicable learning procedure and whether the correlation fault returns. Other speed-sensor or network faults still require their own diagnosis. The bulletin provides no universal acceptable speed difference or permission to replace the transmission based solely on P215C, and its historical calibration should be checked against current service information.
