Hey guys I recently picked up a 4l80 for my 91 Chevy and it did work with the guy I bought it from but when i installed it I seen the tail shaft spin to verify it was good then when I bolted the trans case and drive line up it did absolutely nothing,
so I went to see if it was pumping fluid and of course it wasn’t so I verified it was full and it was but I didn’t give up there and I ended up checking the line and I ended up sucking on the lines and I couldn’t suck anything thru at all, I even tried to blow thru it and can blow if I tried hard enough I can kinda blow thru what would cause this I’m stumped
