I would replace the basket drive. Those ears are too worn to sustain spinning for any length of time. You'll also need a new drive block. You'll also have to sand down the pitting on the agi shaft to pull the trans out of the basket drive. If you pull it all apart you can check the clutch lining for wear. If it's down to the rivets then it needs a new clutch. That one is the 6 pad. Make sure you add some turbine oil to the main bearings when you reassemble it.
