disturbance is most noticeable.
10. Record the engine RPM obtained on the scan tool and the
most dominant frequency reading if obtained on the J
38792-A.
11. If the disturbance is still noticeable, re-index the torque
converter again to obtain the least amount of disturbance.
Has the disturbance been significantly reduced or eliminated?
Replace the out-of-balance transmission torque converter.
