if only you opened your eyes you wouldn't even have had to post a question:

Personally, after switching to carb and losing lockup, I am going to go with this: http://shop.store.yahoo.com/whitespi...i70coloki.html
I trust them enough, so I am confident that it will work fine.

You should try searching I know someone had a link that show'd how to modify the wire connectors so it automatically locked up the TC once it shifted to 4th gear. I'm just gonna put in a throw switch I think, cause I don't want to take a chance with a kit (my trans doesn't downshift out of OD at all). That way I just throw a switch once I get out on the highway or on the interstate and boom I'm locked up until I click it off. I do most of my driving around town or in the country where there's a lot of turns so I don't really see OD that much of long periods of time.

Two easy solutions.
One way is to go to a local Auto Tranny shop or Trans Parts wholesaler. They have Mechanical 4th gear lockup valve that replace the electronic switching. Several company's make them.
Other way is to Purchase a Transmision Torque Convertor Lockup kit. Several companies make a kit with everything that you need. Painless Wiring has just such a kit. Part #60109
700R4 TC Lockup kit
I believe that Summit carries a house brand kit as well. May be cheaper.
Edit: Oooops.... didn't see Bandit5's link...LOL
The Painless kit is an exact collection of all the parts that GM used on the Carbed LG4 motors to engage the Lockup TC. Excellant way to go.

Nope just the pan. A transmission shop should have no problems doing it for you. All you're doing with the kits is replacing some swtiches on the valvebody and running some wires.

Here was the setup I was going to do for my car. https://www.thirdgen.org/newdesign/t...ueswitch.shtml
Like I said I don't normally see OD for long periods of time and I'm usually on and off the brake if I do which should unlock tq converter.
