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.
Park Mode
While the transmission is in Park with the engine idling, Fast Learn will cycle through a series of tests where C3 and C4 clutches are repeatedly applied to learn their clutch characteristics. During the C3 and C4 clutch apply/release procedure, Fast Learn is able to characterize the "A" and "B" solenoid pressures corresponding to clutch return springs, and also is able to learn the volumes for C3 and C4 clutch packs. In addition, C5 clutch is repeatedly applied and released in Park to purge out air for later learning of its clutch volume.
