« on: February 03 2013, 09:58:54 AM »
Can someone clue me in on how these transmissions work? Is there like 3 OD's...or what's the deal?

the 4+3  is a T10 manual 4speed trans with an overdrive on the output

the overdrive is switch engaged  and can be used  on 2nd 3rd and 4th gear reducing the ratio of each gear so you have 4+3 gears

A lot of broken parts does not make you a racer; it makes you a slow learner.
