Insalling new transmission gearcase

Brand:Maytag
Model Number: MVWX700XL1

New Transmission came with a new nylon mountin hub with clip to hold te tub to the drive shaft.

My old one (14 years) is installed with the aluminum drive block kit that requires the TB123A spanner/wrench for removal.(very tight and requires lots of force).
My question is….. Is the new nylon/plastic mounting hub that came with the new gearcase a direct replacement for the aluminum mounting kit that was originally installed?
The old one is not easy to remove ….it requires strong whacks of a hammer plus the spanner/wrench to remove it. The new nylon one is jut the hub and screws plus a clip!
