Exclamation Re: 6 speed suddenly rough shifting

We have fully diagnosed your transmission concern. We found a broken planetary gear internal in the transmission has caused the failure. There are chunks of metal in the transmission pan and this metal has done damage to other components. The cost to rebuild this transmission unfortunately exceeds the price to replace it. The price to replace the transmission is $5,806.00. You will receive a 3 year/100,000 mile warranty on the replacement transmission.
Well, that sucks! I guess I should have spent a little more and ordered a brand new 2020 since now between the pickup and the topper and the new transmission I will be about $30K into this truck.
