90037042022-09-26. Service bulletin. SEATS; FUEL SYSTEM, GASOLINE; AIR BAGS; POWER TRAIN; BACK OVER PREVENTION; ENGINE AND ENGINE COOLING. 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.

90040122020-05-18. Service bulletin. AIR BAGS; ELECTRONIC STABILITY CONTROL:AUTOMATIC (ASC); VEHICLE SPEED CONTROL; SEATS. Power Latch W/AJAR Prior to ordering this part for a customer stating the Tailgate will not auto release or Ajar light is on when the tailgate is closed, first try adjusting the tailgate strikers to minimize the force required to close. The striker must be centered up/down in the latch opening. You have to balance tailgate flushness and closing effort by moving the strikers fore or aft. Striker position also affects closing effort. In most cases moving the right side striker rearward or the left side forward fixes the issue and maintains flushness within tolerance. On the standard tailgate, the ajar switch is on the right side latch only. Please contact FCA Redacted Content for diagnostic assistance and information to assist in problem resolution. If no response in 15 minutes, proceed with repair.
