I was going to try some ATF when I get home today. I really was just wondering if these were even serviceable. It seems like you would have to destroy the guts to get it apart...
I am not going to warranty it because I didn't buy it new. As I mentioned in my post, I bought it at a yard sale. I would be willing to pay a few bucks and get a rebuild kit if one were available. I am not going to put the local Matco guy out since I have never purchased anything from his truck.
I was hoping someone would have some insight on how to dismantle the wrench and replace the guts with new parts.
