"Not sure what tranny you are talking about but the AW70L and AW71L have 3 gears plus OD plus the torque converter lock up. 4 gears if you will plus the lock up."

The AW70L, 71L, 72L, 4 speed or 4 gears with OD I will, and with lockout it has been very informally, referred to as the 5th gear, or like a 5th gear but of course not a gear as you said.

I remember comparing RPMs with my son, while on the cell, who has a turbo some time back. I don't remember the details and is probably groundless if he has a different rear end. I normally don't pay attention to the tach at higher speeds unless and I was beating carbon off the valves in a lower gear. I really must do this soon in my 244 town car. I'll check RPM at 65MPH in the 940.
