Automatic Transmission Torque Converter problems of the 2012 Chevrolet Traverse

Whining and winding sound on acceleration at all speeds. . Rumbling noise from engine. Strut leaking and front suspension issues. This turned out to be transmission and torque converter. Along with pto pinion seal, crankshaft seal, water pump, harmonic balancer, struts, sway bar links, and drive belt.

While driving the vehicle will shudder and lose power, occasionally the vehicle will stall almost like it is attempting to grab gears while down shifting and it will cause the whole vehicle to shake, it has happened so hard I have had to exit the interstate for worry of mine and my passengers safety. The vehicle upon entering will slam into gear and when driving in rural areas the transmission even feels like it is slipping and the car will jerk back and fourth until it grabs a higher gear. I purchased the vehicle in 2018 with just over 100,000 miles and even now the vehicle is only sitting at roughly 132,000 miles and has has regular services to maintain the vehicle. Upon further investigation, the Traverse has several complaints of this same issue including older and newer vehicles, and most have resulted in torque converter/transmission replacement. The vehicle has stalled completely in the middle of intersections while attempting to downshift for take off and has also done so while attempting to merge onto the interstate. The issue was originally noticed towards the end of 2019- to early 2020 and has proceeded to get so bad we no longer trust the integrity of the vehicle for family trips or even to routine doctor appointments for fear of the vehicle stalling in heavy traffic.
