Overdrive failure

Hi, I'm one of the auto experts on RepairPal's Car Genius team! Great question! An intermittent overdrive issue is definitely worth paying attention to before it becomes a more serious problem! On your 2019 Buick Encore an overdrive that fails occasionally and then recovers can point to a few different causes including a faulty overdrive solenoid, low or degraded transmission fluid, or a transmission control module that is beginning to act up. The intermittent nature of the problem often points to an electrical or fluid related problem that can be addressed before causing major damage. I’d recommend having a qualified shop pull any stored transmission codes and check the transmission fluid condition as a starting point, as these two steps alone will likely point toward the root cause. Catching this early is important since transmission repairs that are addressed promptly are almost always significantly less expensive than those that are left to worsen.
