hydraulic tob AN fitting
It was leaking so I disconnected the lines, and it looks like its supposed to have an AN-3 threaded into the TOB... also not sure if it is O-Ring Boss or not. Can anyone tell by these pictures if it's supposed to have an o-ring on the AN fitting or not? Is there any harm if I put an o-ring on there and it's not supposed to have it?
I would just try it out and see what happens but it's a real PITA without dropping the trans.
Thanks!!
