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.

P140402142022-08-29. Service bulletin. SERVICE BRAKES, HYDRAULIC. New Safety Recall Advanced Communication ? P14040214 Chrysler Group LLC (Chrysler) announced a safety recall on certain 2011 through 2014 model year (WD) Dodge Durango and (WK) Jeep Grand Cherokee vehicles. Some Jeep Grand Cherokee and Dodge Durango vehicles may have a brake booster that could prematurely corrode. If perforation of the brake booster shell (due to corrosion) occurs, the brake booster may ingest water during vehicle operation during wet weather conditions. A brake booster that has experienced water ingestion may have the brake function compromised if the water inside the brake booster freezes. The driver may be required to apply additional application force to apply the brakes during sub-freezing driving conditions. An unexpected additional brake pedal application force requirement could slow the driver?s brake application reaction time and cause a crash without warning. Chrysler will conduct a voluntary safety recall on all involved vehicles to inspect the brake booster for corrosion. Brake boosters found with excessive corrosion will be replaced. All boosters will be equipped with a shield to protect the brake booster crimp joints from water exposure. Dealers will be notified of the launch of this safety recall by way of established methods used in the past. We ask that you please take the time to ensure that your personnel are aware of this communication and are prepared to execute a customer friendly process for inquiries on involved vehicles.
