There are two acceptable lifting methods for the CX31 transmission. Option A utilizes Columbus McKinnon hoist rings at the two side transmission mounting pads and the two rear transmission mounting holes. Option B utilizes 1/2" J-hooks in the designated holes on the two 2 lifting brackets (one on each side). There are lift films on the bracket to indicate which hole to use on the right side bracket. Also note that only Option A or Option B can be used, but no combination of the two. The transmission is designed to sit level on the transmission's six base supports as shown in Illustration 5.
Care must be taken when lifting to avoid damaging the following components that are mounted externally on the transmission: ECM, ECPC valves, solenoids, wire harness and sensors.Altitude RestrictionsNote: There are no restrictions based on altitude.
