So did some better inspection on my gears. The output shaft looks fine visually, no pitting to be seen with naked eye.
The input shaft has some pitting on the 4th and 5th gears, on some of the teeth (i'd say on 1/4 of the teeth). These are the worst ones. 3rd gear has slight dents on 2 teeth also seen on the photo.

Most of the other cogs on the 5th gear look fine, like the one behind the 3 pitted cogs. Looks like I got the older 3AJ gears with 19 teeth 5th gear.
Is it even worth it doing anything on this engine if I put this back into the engine? How long before this starts giving trouble? Does this gearbox still have some KMs in it without spraying chunks of metal all around the engine?
I'm assuming people replace them with XT600E gears or something? I looked at the input shaft and it seems the gears are part of the shaft so I'm guessing they need to be pulled/pressed...? Do later 3TB+ gears just swap on?
