That isn’t to say that you won’t find other things inside the trans worn out as well.

I would personally recommend a full rebuild of all the clutches for 1-4 gears and reverse. Also examine everything else while in there for wear, with a rebuilt or new valve body and TC. It is NOT a difficult trans to rebuild, for your first time. You will have to take your time. There’s a DIY somewhere on google for the 722.3 I believe.
