Service bulletins for the 2014 Ram 1500

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.

90030812023-01-17. Service bulletin. ELECTRICAL SYSTEM. Dielectric Grease This product is no longer approved for use on ignition coil and spark plug boots. Current plug boot material(silicone) is not compatible with this grease and can cause deterioration over time.
P130402142023-01-17. Service bulletin. POWER TRAIN. New Safety Recall Advanced Communication ? P13040214 Chrysler Group LLC (Chrysler) announced a safety recall on certain 2014 model year (DS) RAM Truck (1500 series). The transmission case may have an improperly machined park rod guide plate mounting surface. This could cause a loss of park rod guide plate fastener clamp load and eventually the park rod guide plate fasteners may loosen. A loose park rod guide plate and fasteners may not allow the park pawl to fully engage. This condition could cause unintended vehicle movement and cause a crash without warning. Chrysler will conduct a voluntary safety recall on all involved vehicles to inspect the transmission case. Transmissions found with an improperly machined park rod guide plate mounting surface must be replaced. 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.

90037042023-01-09. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN. Transmission Oil Pan, Heater (TMU), Tube or O-ring Applies to vehicles equipped with 8 speed transmissions only; if you have a leak that appears to be at the pan the use of proper leak detection is recommended. The fluid in the 8 speeds can be detected with a black light and there are aftermarket spray on leak detection materials to help ensure that the leak is properly diagnosed and not from another location such as cooler lines, heater tubes, or case porosity. Please note that the transmission pan gasket is available for many of the 8 speed applications FCA offers. Please review the available quick connect and transfer tube parts, as replacement of the TMU may not be required. If a TOC line connection is found to be the source, the quick connect may need replacement. If the leak source is coming from the connection of the TMU to the transmission, the transfer tube may need replacement. When parts are returned to the QEC the retaining clips (snap ring) for the quick disconnect fittings are missing. (This leaves a question as to whether the clips were missing from the assembly plant, or the technician removed them in order to make line removal easier.) Please return the clips with the transmission heater and note if they were not there to begin with. For any questions regarding transmission heater, contact FCA Redacted Content. If no response in 15 minutes, proceed with repair.
