the tranny was made by Doug Nash... it was basically a Borg Warner Super T-10 with a Powerglide attached as an overdrive unit.
The OD unit was bolted to where the tail shaft housing went.
The +3 part meant that OD was available in 2nd, 3rd and 4th gears.

With the 87 models, it is possible to have the tranny go into 1st-over depending on RPM. If you are in really slow city traffic and you have stopped and shifted into 1st, once you start moving at slow speeds with no real acceleration, the tranny will go into OD in 1st. With part throttle at that point, the OD will shift out and will remain out until 4th gear.
