What did you find out?

The HT755 is a 5-speed, but has 6 apparent/effective gears in terms of rpm changing. When flooring mine from a stop, the gear shifts occur approximately at:

0mph 1st gear
18mph 2nd gear unlocked
27mph 2nd gear locked
36mph 3rd gear
45mph 4th gear
60mph 5th gear

Upshifts occur at 2100rpm and drop to 1670rpm
