This is a pretty wild shot from the hip, but I was wondering if anyone has ever considered a M76 version of the 4t65e transmission to be installed into a Bonneville? The M76 was used in some U-bodys, such as the Aztek, and has AWD ability.
Obviously, it would take some work, but I wonder how difficult it would be to swap in the rear member and driveshaft from an Aztek to make it work in a Bonneville. I've never peeked under an Aztek, so I'm not real sure what it looks like.
Specifically, I'd like to do this to a H-body Bonneville... to me the the biggest drawback to my Bonne has been the inability to deliver power to the rear tires, and I have long figured that once my Bonne has finially given up the ghost, I would convert it to RWD with Camaro parts and a MIG welder... but I wonder if Aztek parts might be an easier way to go (Easy being a relative term).
How stout is the Aztek driveline? All the Aztek problems I've ever heard of (aside from styling) is the 3.4 engine.
