it has a busted 3rd gear. the owner keeps saying it's a World Class but it has tremec stamped onto it.. (so he says.. i havent been out to look at it yet) the guy is a friend of my brother.

is world class somehow affiliated with tremec or does he just not know what he's talking about?

also what are some tips on telling the difference between the TKO and the 3550? how much are rebuild kits for the two? thanks.

Well..

if i'm not mistaken.....tremec started making t-5's a few years ago....so if he thinks it's a world class...then it very well might be a tremec built t-5. You can tell the difference between a tko and 3550 by the # of splines on the output and input shafts.....3550 is the same as the t-5.....tko has the gm input spline count (think 31?). Plus they should have a metal tag on them maked with which model it is.
