You will need to purchase the special spanner wrench for the tub nut (left hand thread) and tub bearing set AP4372971 and seal kit AP3538707
You will also need a steel rod to pound up and out the old sleeve bearing stuck on the tranny shaft. When done, oil the bearing with light non-detergent oil. A routine job for a good mechanic.
You will need 3 hours for the job, I quoted $180 for the job but probably not enough.
