You are not alone in experiencing the confusion with this repair. Maytag re-engineered the part, and adapted it for a high torque transmission, and we really do not know how it affects your model since your model number is not included on the tech bulletin Maytag issued, but the part is appropriate for your machine.
Here is a series of posts from another person on the issue, and it includes a link to the tech bulletin. See if it helps.
