Picked my Yukon Denali up from the dealer February 11th with 6 miles on it and returned it to the dealer February 14th with about 50 miles with a transmission leak. This is why I'd say my Yukon was built with this issue. This is the shaft running from the transmission to the transfer case. The Tech showed me the shaft had a dent / gouge in the area where the seal sits causing the seal to leak trans fluid. I don't think it was losing a ton of fluid, but it really does smell when it gets onto the exhaust. Anyway, I contacted GM customer care and they are following the repair, but it took 6 days for the dealer to get the replacement part and as of today (2-23-22) I still have no truck. GM Customer care told me after the repair is complete, I'll get extended coverage on the transmission and hopefully a few oil changes.
