ATS - Paag - Perfect All Around Gearboxes (1.41.x)

3 boxes intended to drive at 45 / 55 / 65 mph at optimal low rpm.
Optimized for engines with max torque @900/1000/1200 rpm.

For vanilla trucks, Kenworth W990 by Harven, Freightliner FLB by Harven, Mack R

I don’t like changing gearboxes all the time. So I tinkered these universal gearboxes with fantasy ratios.

PAAG 16-2/4: Forward 16+2 Gears, 4 Reverse, 3 step retarder
Diff 3.1: For engines with max torque @ 900 rpm
Diff 3.34: For engines with max torque @ 1000 rpm
Diff 3.32: For engines with max torque @ 1200 rpm

They are intended to start with heavy loads uphill with low gears, and drive at 45/55/65 mph at optimal low rpm.
