If i were you i would keep the 10R80. while having a stick is more fun, it doesn't compare to the consistency of the auto, I actually want a new 10speed, I have a stick car.
I Have DSS 1200 hp rated axles and the aluminium driveshaft, I can say it has been holding up well, no complaints.
but on the other hand im only pushing about 680 rwhp.
I wonder if OP really thought damage caused by an accident was really covered under warranty lol.
+1 on the Roush bumper, fits like OEM and looks better then the stock front bumper.
I don't know if anyone has said this but the GT is the better car. me personally I would still go with Bare Base GT over a optioned out Ecoboost every time.
