2. Obtain J 24171-A and install a 90 degree hook onto the end of the slide-hammer (1).
3. Position the 90 degree hook behind the rear face of the seal's outer case (2).
4. Remove the rear seal using the slide-hammer.
5. Inspect the seal bore for scratches. Remove any scratches in the seal bore using crocus cloth.
Installation Procedure
1. Important:
Be sure the new seal has blue sealant coating the OD (4). This identifies the seal for use in the 1000 Series transmissions. The blue sealant
identification is important because the 1000 Series transmissions have an overdrive ratio in fifth range and there is a potential for high output shaft
speeds and resultant high seal temperature.
Align the seal so the seal lip (2) is outward and the face of the steel case (1) will be against the driving face (3) of the tool. Install the new seal onto
J 43782.
2. Slide the installer tool over the output shaft until the seal enters the seal bore. Strike the installer tool with a mallet (1) to drive the seal into the seal
bore. The seal is installed correctly when the shoulder of the installer tool squarely contacts the outer surface of the rear cover.
3. Install the yoke assembly onto the transmission.
