In early August 2026 the transmission began shuddering at low speeds. Reported to the selling and servicing Chevrolet dealer on 08/11/2026 at 118,892 miles. No transmission diagnosis was performed; the dealer's written estimate recommended spark plugs on a diesel engine. The condition worsened. On 09/17/2026 the dealer verified the concern and documented a \"very harsh shift which would continue until 5th gear\" when accelerating, and found the transmission fluid \"heavily contaminated with metal and clutch material.\" The dealer recommended transmission replacement at customer expense and stated GM Special Coverage N242454441 (transmission control valve wear, companion to Safety Recall 24V-797 / GM N242454440) does not apply because DTC P0747 is not set, although that bulletin lists harsh shifting as an effect of the worn control valve. The control valve body has not been inspected. GM's recall filing states this wear can cause harsh shifting and in rare cases momentary rear wheel lock-up. No warning lamps or messages appeared before the harsh shifting. No crash, fire or injury. The vehicle and transmission are at the dealer and available for inspection; a GM TAC/FSE inspection has been requested. Filing so NHTSA has a record of a 2022 Suburban diesel showing the recall symptom and being denied inspection on the basis of the P0747 code alone.","products":[{"type":"Vehicle","productYear":"2022","productMake":"CHEVROLET","productModel":"SUBURBAN","manufacturer":"General Motors, LLC"}]}]}
