I have found that my TH350C transmission mated to the 350SBC in my '57 is leaking oil through a 4 pin connector on the driver side of the tranmssion. Here is a link to the part: http://www.rowand.net/Shop/Tech/images/TH700R4WiringConnectors17.jpg

Any clues on how to repair or replace? It is a plastic piece and I dont want to just yank and break something off...

Thanks!
