If you have a clunking problem during shifting I reckon you'll end up with this problem

in the end.
Having seen the growth of this problem in my transmission (722.118 vacuum only) I started this thread to try and find a solution. I didn't really get one in the end but here it is

I've more recently taken another 722.118 transmission to bits and found that this type of spline wear isn't limited to just the front planet gear set. You can see the same type of shimmy wear on the second planet gear too.
I urge you to solve this problem ASAP. Clunks are bad news for a 722.1 (well bad news for any transmission). If you want to see what's involved in a rebuild I've put loads of pictures in this thread

My advice is not to think that this is something you should learn to live with.
