Go here will tell ya everything ya need to know with diagrams : Welcome to guzzle's TC Lockup Mod Web Page
My dad did this mod to his 97 F250 460 powered truck. I believe they have the 4r100 trannies? He made his own box and has a toggle switch to lock the converter up. Yea just make sure you flip the switch at the stop lights haha. He also made his own "chip" for changin his airfuel mixture. Has the air ratio meter in an a pillar pod too haha. He loves lil gadgets and tinkering.
97 would be the E4OD. It's identical to the 4R100.
Thanks trackspeeder for clearin me up there. So they just gave it another model designation??
Hate to 'revive' this old thread but I've been looking into making my EBPV into a exhaust brake and since I have an auto I've been told I need a TC lockup mod. From what I've read its an easy mod to do. My question is, if I turn off the manual TC lockup does the TC go back to normal? (i.e. it locks up when its suppose?) I don't haul huge loads (heaviest load I've pulled was about 9,000lbs or so) but I do have to travel down some pretty steep mountains to get to my destinations and would love to not have to touch my brake to maintain safe speeds. I'm really new to Auto trans and don't really know all the lingo for them so you'll have to explain it to me like I'm a complete idiot lol.

I did it on my truck, it works to an extent, just dont go crazy braking at high speeds or the pressure will over power the exh. vavle springs and bad stuff will happen haha
