Any thoughts about 2 different TC-types? How do you suppose to upgrade the tranny to 6-speed?

Nick, I was under the impression you could swap the tranny and the case. Is it not possible? Dragon, I read another post like yours about the 10 mph in 1st thing, and I just don't understand? Mine doesn't perform like that. That's why I asked if there was a possibility some were different. I like 1st! But, I see some owners here disagree. My 1st will lay your ass back in the seat! LoL, pardon my language. It's just that last gear (6) I need for freeway cruising, and I'm getting the impression from Nick it's not possible. The one good thing I have going for me is my tranny still performs like new, it's been babied since day 1.
