Well I went and picked my transmission today. It took me 5 hours to travel 110 miles due to a wreck on I-12. A section of it was shutdown. 5 hours over and 1 1/2 hours back! Anyway, it was taking so long, the guy argeed to meet me a pretty good way from his house with the transmission. So, we're standing in O'Reilly's parking lot looking it over and I spot an  electrical plug. He said it has the electric lock up converter. He said one of the three wires was hot (ignition), one was ground and on I wouldn't need.
  Anybody know which color goes where?  Can't you run the hot wire through a toggle switch for a little more control of the OD?
 One more question: Is it a 700r4 or a 4L80E? Or did some 700r4 have electric lockup converters?

Irish, it's on the driver's side about midway the length of the transmission. It is kind of rectanguler and it has has three wires coming out of it. At least I got the plug and the wires.

Some 700R4's did have a lock up converter (I've had two).  There are some posts around here somewhere about locking it up with a switch.  I did a quick search and summit has a kit to control it automatically or with manual override (switch).  http://www.summitracing.com/parts/TCI-376600/

Also 700s were never ecm controlled, they were renamed 4l60e when they went electronic.

NOT True! i have a 7oor4 from an 87 camaro 305 in my truck. it has a lock-up style torque converter which is computer controlled to lock in 3rd and 4th. for anywhere between about $75 and $150 you can get a stand alone controller for this style converter. kind of a hassle But worth it for the gas milage. my truck has 4.11 rear gearing so that Really helps me. totally drivable and holds iup to a mild small block 400 i think its a great choice good luck with your install!

All 700R4's (4L60's) had the lock up feature. The only difference is how it's controlled. If you do a search on the forum you will see this discussion with several solutions.

Thanks, I found out which wire goes where. One is hot, (violet) one is ground (tan with a black stripe) and one you don't use at all (blue). The guy I bought it from said he installed one in his Chevelle with the same plug and he ran his hot wire through a toggle switch to turn the lock up on and off. I'm thinking the current TH-400 already has an ignition keyed hot wire running to it. I think I could route it to a toggle mounted on the dash. Any thoughts?

I would do it right or don't even bother hooking it up and just hook up an auxiliary cooler.

Vile, you're right. I believe that anything worth doing is worth doing right. Plus, it's so hot down here already, it would really hurt to have to pull it all back out. Thanks for all the input guys. I have learned a lot aboutthese trucks since joining this site. Your all the best.

jaredts, I keep a copy of Summit's catalog in my ....."library"  ;)but I did not notice that kit until you pointed it out. Thanks,
