Ok so I bought the truck and it was slowly leaking from the bell housing. I figured the pump seal. So this weekend I dropped the transmission and replaced the seal. Within a hour the dang thing was leaking again and is leaking worse. It started leaking the old fluid that was left trapped inside my transmission and then within a day the new fluid started coming out. Today I took it to a transmission shop and they told me that there was to much pressure inside my transmission and a flare from 2nd to 3rd (So basically a slip). I have yet to pick the truck up and am wondering if I hooked up the transmission throttle cable spring back up. I have never felt it slip, so I am thinking that I did not hook that up and the cable is sticking a little causing the over pressurization and causing it to leak out of the seal. Does this make and sense you or am I going to need a rebuild?
