- [SSM 52314](/bulletins/10251934.md), 2024-03-20, Service bulletin: POWER TRAIN. During service and repair requiring removal and replacement of a crankshaft bolt and/or crankshaft damper, achieving proper torque of the crankshaft pulley bolt is critical. Incorrect torque may allow the bolt to loosen resulting in the timing gear breaking and engine damage. Replacement of the bolt is critical to the repair and accurately following the installation procedure in the Workshop Manual \(WSM\) Section, 303\-01 is extremely important. The bolt torque procedure can be found in the crankshaft front seal removal and installation procedure or in the engine assembly procedure.
- [SSM 50615](/bulletins/10209220.md), 2022-03-22, Service bulletin: POWER TRAIN. Some 2017\-2022 Ford GT vehicles may exhibit diagnostic trouble code \(DTC\) P166B present in the gear shift module \(GSM\) after an on\-demand self test is performed. This is likely due to the driver door not being fully closed and locked during the on\-demand self\-test. A false P166B DTC can set if the driver door is not fully closed or if it is unlocked during the self\-test. If P166B is still present with the driver door fully closed and locked during the on\-demand self\-test, continue with normal diagnostics in Workshop Manual \(WSM\), Section 307\-05.

Some 2017\-2020 Ford GT vehicles built on or before 10\-Sep\-2020 may exhibit a rattle/buzzing noise from the left rear of the vehicle during hot idle. This may be due to the transmission control module \(TCM\) calibration. To correct the condition, follow the Service Procedure steps to reprogram the TCM.
