The 3550 was both a product and a product line.
The product line encompassed the 3550 and TKO models. Each model had
two versions, One being a 0.68 overdrive and the other being a 0.8
overdrive. The difference between the two models was in the gear ratios
and the input shaft spline count,. as explained below.
In 2004 the 3550 and TKO were replaced by the TKO-500/600 product line. Today
the 3550 and TKO is only available as a used or rebuilt unit. Service
parts and upgrades are available such as carbon fiber synchro rings and
steel forks.
