This is from a press Release When Honda Introduced Prosmatec Transmission so @mubeenshahid is worng here again . Prosmatec Was NOT Introduced by Atlas Honda. It is something Honda Introduced and it is different from Automatic Transmission
(Prosmatec Transmission with Lockup Mechanism)
• The new transmission features an active lockup mechanism that engages even at low speeds, and achieves top-of-its-class fuel economy through precision control that is tuned to the vehicle's driving conditions and throttle opening.
• This is the first time Honda has incorporated its proprietary direct control system used in Accords and other models in a minicar. Linear solenoids provide precision control of the clutch pressure, ensuring a smoother gear shift feel.
The Prosmatec (PROgressive, Shift schedule MAnagement TEChnology) transmission provides a smooth ride when ascending or descending hills. The system evaluates driving conditions based on the throttle opening and acceleration, and optimally controls the timing of gear shifts.
