pre-maid trans lines or press fit lines

Basically go to Home Depot or Lowes, and buy an 1/8" or thicker piece of aluminum and a heavy duty chisel as seen in the video (about $12). No saw, no tape, no $100 hose cutter. It takes me barely 3 minutes to assemble a braided end for normal hose and 5 minutes for Teflon hose. Heck, if the hose is 1/2" too long, I redo it.
For trans coolers I recommend AN6 Teflon hose because it has a smaller outside diameter, can handle any fluid and easily handles the pressure.
