Guys- correct me if I'm wrong here...
There are two bands and two clutches in a 904/727. The combinations of them being applied give you the 3 forward gears and one reverse gear. The parts are named both for their various functions and for thier placement in the geartrain so it can get confusing:
- The Low/Reverse band is in the back of the case - It's only used in "Break-a-way first" (meaning standard valve body manually shifted and held in "1") in combination with the applied Forward clutch and the sprague; and in reverse when it's applied and acts against the sprague.
- The Forward clutch is actually the rearmost clutch in the geartrain - but it's applied in all forward gears, hence the name.
- The "Kickdown" band - or second gear band applies to the outside of the high gear clutch drum which is the most forward mounted drum and is applied with the forward clutch to get 2nd gear.
- The High gear clutch - inside the high gear clutch drum, which applies with the forward clutch to get 3rd gear.

There are some good books on 727s for under $20. Buy one and read it - it's easier to see the pictures and the flow through the various components.
