When changing the oil filter and installing the new filter seal\(s\) in the oil filter housing, special attention is required.
- [26 13 17 2027945](/bulletins/10212658.md), 2022-05-31, Service bulletin: ENGINE; POWER TRAIN:AUTOMATIC TRANSMISSION. Humming or metallic rattling noise from under the vehicle, heard most consistently during engine idle or slow acceleration. Initial inspection indicates that the noise is coming from the exhaust system. Relative movements in the rear mounting of the exhaust system \(rear silencer\).

As the sump pan gasket settles, the torque of the bolts decreases and the seal may leak. Automatic transmission fluid is leaking at the sump pan gasket.
- [37 13 09 2028715](/bulletins/10210652.md), 2022-05-02, Service bulletin: ELECTRICAL SYSTEM:12V/24V/48V BATTERY; POWER TRAIN:AUTOMATIC TRANSMISSION:INTERNAL:GEARS. After a mechatronics, torque converter, or complete gearbox replacement, the clutches must be adapted to the new component. This requires a gradual move of the clutch linings toward the optimal operating points in the most diverse load conditions. As a result, sporadic driving power disruptions lasting for less than a second or reduced shift comfort are possible over the first 500 miles. This is normal, and these issues will decrease over time. The issues can also occur if the adaptation values of the gearbox were deleted.
- [37 12 75 2029808](/bulletins/10210642.md), 2022-05-02, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). New software in the Transmission Control Module \(J217\) addressed the condition.
- [A371394 2033065\-](/bulletins/10123984.md), 2017-11-17, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); ELECTRICAL SYSTEM:SOFTWARE. Shift quality concerns: harsh 2\-3 shift. Incorrect software calibration causes harsh shift points.
- [A371431 2013002\-](/bulletins/10122418.md), 2017-11-08, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:COOLING UNIT AND LINES; POWER TRAIN:AUTOMATIC TRANSMISSION.
