Automatic Transmission

999 “Bad Boy” Description 

The A999 "Bad Boy" is generally used in Jeep/Dodge applications where an overdrive transmission is not needed (such as a vehicle that will not see long distance freeway speed use) or a shorter transmission is required (Such as a CJ5 Jeep).

“Bad Boy” is a designation  High Impact adds to a custom built automatic transmission to differentiate it from a stock replacement transmission. These transmissions are built for aftermarket conversions and applications where the demands placed upon the transmission far exceed anything Chrysler/Jeep ever built the A999 for 

There a number of standard upgrades included in all Bad boy units, such as an upgraded HD torque converter with furnace brazed turbine elements and HD lock up clutches, oversize sprags, upgraded pressure regulator and reverse boost valve, and internal modifications for improved oiling and shifting.

 A Bad Boy A999 is typically engineered and built for a specific application.  Racing applications require ability to handle hard shifts high RPMs as a matter of course. 4WD applications must operate reliably at crazy angles, and not slip, even at very low crawling RPMs. Towing applications must be able to withstand sustained high torque. 4WD and Towing both tend to exaggerate the heat loads. Shift firmness and shift points are calibrated to the application.

Generally speaking, any High Impact  “Bad Boy” A999 transmission will withstand 450 ft-lbs of torque, 450 HP, 6000 RPM. It will then be further optimized for the specific application.
