The "RPM Drop" plot shows the change in RPM at each shift. The standard A65 is almost a straight line with 1000 RPM drop at each shift.
The T140 is almost flat on the last two shifts. The Quaife has a higher RPM drop on 4th-5th than the 3rd-4th, more like an overdrive. Mine is a little more progressive declining curve with each up shift.
The T140 has a slightly higher 1st gear than mine but it is less than 2 MPH difference at 7500 RPM.
Quaife has the highest 1st gear.
