Automatic Transmission Control Module problems of the 2016 Chrysler Town & Country

After the Chrysler dealer in glendale CA completed recall s44 – transmission oil pump on my 2016 Chrysler Town & Country in October 3 2025, the transmission began to malfunction and eventually stopped shifting completely. The dealer drained the transmission fluid, removed both front axles, removed all transmission components, and replaced the transmission oil pump, seals, bolts, and torque converter as required by the recall. The transmission is available for inspection upon request. Safety risk: the vehicle became unsafe to drive when the transmission began shifting erratically and then failed to shift at all, causing sudden loss of acceleration in traffic and posing a risk to myself and others. Diagnostic codes: before the recall, the vehicle had code p06de (engine oil pressure control). Chrysler has a documented TSB for p06de requiring a pcm software update, but the dealer did not perform this update during the recall. After the recall, the vehicle developed new code p0760 (shift solenoid c malfunction), which was not present prior to the recall and appeared only after the transmission was reassembled. Inspection and confirmation: the dealer confirmed p0760 but refused further inspection or repair, stating it was “not related,” despite the failure occurring immediately after major recall-related transmission work. The vehicle has not been inspected by the manufacturer. The failure is reproducible: the transmission will not shift. Reason for complaint: this failure happened shortly after the s44 recall, which involved complete transmission disassembly. The combination of new post-recall transmission codes, the absence of a required pcm software update, and the sudden unsafe failure raises concern that the recall work may not have been performed correctly. I request NHTSA review whether recall s44 repairs are causing secondary failures or being improperly completed.
