Hi all, I've got my 4r100 apart due to the diode busting. Luckily, i was only going 5 mph when it let go so it didnt grenade into little pieces. The fluid is still red, although a tad on the dark side. I currently have my Factory Tech Valve Body in there and would like to keep it. What pump mods can I do that will work in harmony with the FTVB? I read that you can drill out the anti drain back valve? Is this correct? I was also checking out the Transgo tugger kit, but it looks like its main focus is on the valve body which I already have. It also looks like I can get the spiral snap ring for the OD seperately. Any insight is greatly appreciated!
