Hey 307 Regal...... When you installed the transgo kit, did you drill out the front pump drain back hole?
The only drilling I did was what was included in the instructions and I didn't skip anything, but I'm not too good with transmission vocab so if I knew what it looked like then I could tell you. There was some drilling done on the main plate of course but there was also one more hole I had to drill. It was part of the assembly you have to remove from the side of the transmission on the passenger side. The instructions didn't say what it was, mainly since they assumed I knew what I was doing, hence the print: "for professional use only." haha
