Does anyone know what year the Tahoe/Yukon started coming with the 8 speed auto trans as the base transmission? We're going to get rid of the Charger and the wife wants to replace it with another SUV. The Charger is a nice car and has a fair amount of power, but it's difficult to travel in when you have to take a wheelchair with you as it takes up the entire trunk. I never wanted another SUV again, but circumstances change.
Also, has anyone heard of a 6 speed to 8 speed swap being done? I'm wondering if it's as simple as bolting it in and doing a segment change and perhaps minimal wiring like a 4L60E to 4L80E swap or if it's a major undertaking. If it's not too difficult then I won't be so picky about the transmission. The 6 speed autos are nice, but I really like the 8 speed in the Charger and if I'm going to be stuck with a full size SUV again I'd like to at least have a transmission that will get it down the road with a reasonable expectation of fuel efficiency when cruising.
