It's like most things in life, make the right decision from the beginning and it's less work and frustration in the end. I'm with you I don't really care where the transmission and diff come from, I just want them to work effectively as a package. I also have little interest in OD I want this truck to be a cruiser I'm not planning any long distance driving. I do expect decent response in traffic and the ability to cruise @ 70 mph on the our local freeways. Hell I'd put in a Powerglide and a Ford 9 inch if that was the best package. I'd prefer to stay with Dodge built components, but sometimes you can't to get the results you want.
