While being driven the vehicles transmission fails to shift gears while rpms are registered the transmission fails to respond and lacks power. I was forced to shift manually to try and get the gears to shift with no luck after quickly making the switch between automatic to manual twice the automatic transmission responded with a loud clank as if the semi behind me had hit me and the responded with acceleration. The issue was reported first early February 2020 again in early may 2020 and recently early October 2020 service department fails to duplicate issue. My dashcam captured video while being driven by the service department expressing the strange feeling the transmission would give them with torque and shifts.
