Check with your trans shop about setting up the shift patterns.I've been told its so much easier to get the one with the computer..But check with your local shop about how to make that trans shift at the right time.The TV cable only dose part of it.Something most guys don't tell you.Is the TV cable only works the 3 gears the Over drive is done with vacuum and shifting points set up By the trans installer.Its costing what ever you payed for the trans think another 1200.00 for the guy setting it up and getting your drive shaft cut down and re-bounced.Don't take my word for it ask your Tranny guy.Me i'm buy the 4L80E with the TCI wire harness and brain that is a bullet proof trans you can drag race with it pull with it leave it in over drive all the time cost me 1600.00 to buy it buy the harness and i don't have to shorten the drive shaft cus most 3'4 ton trucks from 1969-72 had a th400 same drive shaft maybe different yoke.But same all the way around
