Was due for replacing my front seal on my 700R4, saw a few threads on here talking about checking for wear or what not on the torque converter. These aren't any kind of grooves, just markings I suppose. Is this normal? Taken with my cellphone so it's not the greatest.

 

If there's no grooves it's normal.

 

A groove in the sense of it being a deep one? Something you'd catch with your fingernail perhaps? It feels like a fine surface, but just to be on the safe side while I have it all out.

 

When looking at that hub your looking for a few things. At the top you'll see the wear from normal or abnormal pump engagement. Your loos fine.

In the middle youll see wear from the pump bushing. It seems to be placed right and you'll know if there was movement in the bushing because the mark will be very oblonged and out of round.

It looks okay. You can put it on a lathe and polish it with a very fine piece of sand paper.

 

Thanks!
