Gone on Mon. when I get off of work,or before I get their.I don't know if your rebuilding a 700r4,but take your time.I started last thanksgiving an didn't finish until after new years.I made some changes to bring it up to 4L70.It works well so far.The only time I trash it is from 70 to 120 MPH.Soon I'm going to go to a drag strip an get so quarter mi. times.Maybe this coming winter. It a 78 Z28 T-top,no a/c,no heater,no radio,just my fat *** an around 400 HP.
