My Series 80 washer works fine on agitation but makes a loud banging noise when it gets up to full spin speed. When spinning, the agitator moves with the tub as it should, but the lower agitator keeps jerking to a brief stop and then moving again. It is very cyclical. I completely removed the agitator and tried the spin cycle but the same banging noise occurs.

I replaced the clutch a couple of months ago due to a loud bang at the end of the spin cycle, which corrected the problem. Also, I replaced the drive block for the current problem but it did not fix it.

Does this seem like a transmission problem? Could it be the basket drive instead?

Yes, transmission.

Here's the transmission(gearcase) for your model you can order:
Transmission 3360629


Video included in part link.

You can actually do what this guy did and remove the transmission and leave the motor connected to it to verify its doing the same as his:
