This is common on high mileage transmissions that have been run hard in first and third.
It is due in part to the side load that is generated from the helical cut gears.
The two most common causes are;
1. Excessive wear on the output shaft center bearing retainer plate.
2. Fork wear caused from excessive down shifting.

I have also seen excessive 3rd gear end play ect.
Remember to check end play and the mainshaft for wear as well.
I sell a heavy duty tool steel bearing retainer plate. It is found in the transmission section.
