    I am trying to see if anyone has found any upgraded trans lines for the 4l80. I am putting an aftermarket trans cooler with just the slip fittings for standard rubber lines to go onto and use hose clamps to hold them on. Looking for anything bigger and better than the stock lines since mine are leaking.

    ya im pretty clueless on an fittings and such. Ive never messed with them at all. Bunch of local dirt track guys around so Im sure I can get parts somewhere local if I need them, but no idea what I will need.

    Go buy 1 new fitting for the transfer line or just take 1 off the truck and take it to your local hardware store and have them match up the threads and dimensions and buy a new fitting
