tremec 3550 swap

97 Aztec · 12-03-1999, 12:52 AM

I know that the Tremec 3550 is a much better tranny than my T-45 and with my horsepower I know that the T-45 won't hold up much longer. Actually, I'm amazed that it has lasted this long! My question is: will a Tremec 3550 bolt up to a 4.6 or not. Do I have to get a different bellhousing? What one and where if so. Any info would be appreciated.

Yep, need a different bellhousing, Lakewood. Can't remember where to get it though, sorry. With a GT you, need a lengthened driveshaft as well.

Guy I bought my donor trans from when through the same thing you're thinking about. Let me check with him and see if he'd mind if I gave you his e-mail address, if you're interested...

lakewood makes the bellhousing and all you have to do is call them for a part number. Becareful though other people say they make them too"aka sean hyland" but theirs is a lakewood and if you go though lakewood it is less money! Call around your home town to a couple of tranny shops to see who spins their own driveshafts and get one made. It usally is under 200 dollars. fyi spend the extra money and get a tko!
