Greetings square body owners! Here is an interesting find. I am rebuilding a 1990 700R4 transmission and I found some front pump gear wear on one of the pump halves. If you drag your fingernail across it, you can barely feel it. I know there are re-conditioned pumps out there BUT is there a way to carefully re-condition this one? What does a transmission builder do if he runs across this and the transmission was working, only slipping in 3rd and 4th-that was due to burned clutches. I can NOT find any information other than "Carefully inspect the rotor, vanes and rotor surfaces". Can the surface actually be re-surfaced like a flywheel or cylinder head? Many thanks and keep those square bodies rolling!!
