How to check the correct operation of TORQUEFLIGHT transmission bands ? #shorts #how #check #band
Kickdown Servo (Front)
Direct air pressure into front servo "apply" passage. Operation of servo is indicated by a tightening of front band. Spring tension on servo piston should release the band.
Low -Reverse Servo (Rear)

If clutches and servos operate properly, no upshift or erratic shift conditions indicate that malfunctions exist in the valve body.
