Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
A5S 360R Power Flow
The GS 20 module controls the hydraulic valve body through electrical activation of the various solenoids. See Fig 1 . Electrical activation is based on a programmed operation map and transmission operating conditions (vehicle speed, engine load, throttle position, range selection, AGS program logic, etc). Engine torque is transferred by the various drive clutches when activated. The various torque paths enter the planetary gearset as input. Simultaneously, the planetary gearset is provided with reactionary input (held components) from the various brake clutches and free wheel clutches. The output result is five forward drive gears with progressive ratios and a single reverse gear. See Fig 2 .
