Where to mount TH700 manual lock-up switch?

[Logbed]

Hi,
What kind of switches have you used and where have you mounted them for practical operation? Pictures?

On cars/trucks with column mounted headlight dimmer switches I have used a floor mounted dimmer switch.

One project car we used one of the cheap push buttons included in line locks that are designed to slip over transmission shifters. He put it on the column shifter lever and wired it thru a latching relay. One push locked it, another unlocked it.

Lots of options, how fancy do you want to get?

Can you drive around with a 700 not plugged in, without hurting it.

I have a 700 in my vette that i just threw together and started driving, forgot it had lockup. Nothing is wired..

You can probably get away with it, as long as you have a good transmission cooler. Most of the heat in a transmission comes from the converter.

It’s pretty easy to make the lockup functional. It helps fuel economy, and make the car a little more comfortable on the highway.

I would make the converter work,it's easy. I am of the opinion that you are asking for a premature transmission failure,they make kits I can't remember who makes it,so that you can run without converter lockup,IIRC it is a check valve that redirects oil in 4th gear. I'd just make my converter work. I found the kit,snapshotted the description, that description says to me don't run without lockup,unless you perform additional modifications.

What @Ricko1966 said. ^^^

The over drive planetary gear set gets additional lube when the converter is locked.

Thats good to know. I didnt even think of it, never had anything with a 700r4 before. Id be interseted in making it work.
Ive only driven it maybe 2 or 3 miles since i got it running. Itll never see the highway, just for play around the property. It goes like the wind, doesnt seem to slip at all, but i wouldn't want to hurt it.
Pardon my ignorance about automatic transmissions, but what exactly does that do?

If it will never be on the road just limit yourself to 3rd gear.

I have the cruise control on-off switch unused since I have no cruise. It would be in my fingertips so using it would be pretty smooth I guess. I was figuring if I could use it for grounding the green manual lockup wire from my TCi 376600 vacuum lockup control. Anyone done this? Is it properly fused? Any other tips, Im not friends with electricity...

A lockup converter locks the turbine of the converter to the cover inside the converter, eliminating any slip. A conventional converter will have 200-300 rpm of slip at cruising speed.

You could use the cruise on/off switch, the solenoid draws very little current.

B&M 70244 B&M Converter Lockup Controller

The B&M converter lockup controller provides dash-mounted control to govern converter lockup at any speed between 30 and 90 mph. These kits eliminate converter lock and unlock cycling and premature unwanted converter lockup.

The guy that rebuilt my 700r4 installed this
It works well. I finally set it at 55mph and don’t really adjust it any more

I probably could have done this and saved a few bucks I like your idea. Not sure how the brake pedal switch works though. Mine is set to lock up at 55 via the cable/electric switch at the TC so speed sensor only I believe
