2020 GMC Yukon — clunk when changing from reverse to drive

Ask what changed right before it started. Swap the cheap/easy piece first on the 2020 GMC Yukon and see if the fault moves. Don't erase codes until someone who can help has seen them. Write the result down so the next test isn't a repeat of the last one. Heat soak after errands is the other window.

Intermittent stuff lies if you only catch it once. Loaded-suspension checks on the 2020 GMC Yukon catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. On “clunk when changing from reverse to drive,” that was the fork that mattered for me. Have you gotten a second quote in writing? This is the filter I use when the thread starts repeating itself. Video is ugly but it shows the hesitation.

I wouldn't throw parts yet. Get a real battery/charging test on the 2020 GMC Yukon, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. This is from a 2020 GMC Yukon in Detroit. I'd want a dollar figure or a measured spec, not 'should be fine.' Not driving it hard until I know more.
