Purchased a 2020 Silverado 1500, 5.3L 4×4 with 8,000 miles. Now at 66,000 miles the torque converter is bad. Shudders, hard shifting, lunges into gear, wont go into reverse at times. MULTIPLE complaints with these engines. Theres a recall, but it stops at 2019¦.. WAKE UP GM!! This problem is still ongoing from 2020-2024!!! Needs to be another recall
