how to use lock-up switch......?

I'm thinking of doing this tonight, after much consideration- it just seems worth it to me. I've been reading a few do's and donts concerning the operation of them. Anybody care to explain how to use this? from acceleration, deceleration, stopping, when to turn on and off, etc....

I only use mine when I'm up to highway speed and plan on staying there.

I use mine all the time when towing my 5ver. No exhaust brake so this helps me a bit. I am very careful about lugging it though, this is a big no no!

Ditto for me. Only other time is on our steep mountain area logging roads. I'll lock in 2nd to cruise easy at a lower speed and get rid of the heat from the unlocked converter.

It's also real nice to use a relay to switch the lock circuit to ground rather than just a switch by itself. That way, you can use a switch with a light in it to help you remember that it's locked.

I am not sure how your's is wired Yello Yota, but I put an LED on mine. Went to the lock up switch then to a 12vdc source for the other side. When the switch picks up a ground to lock TC it also gives a 12vdc path through the LED. No problem for the lock up, as the LED uses such a small amount of power. Does get a little bright at night as no dimmer is on LED.

Locked shifts will break your input shaft with much power. I did it for a long time. I never broke anything doing it with the stock converter. A while after i put my goerend in it though, I twisted the stock input in half doing locked shifts.

3rd and 4th gears are the best place to lock it. A lot of the time i turn my O/D off and when i get to 3rd I lock it, pull through 3rd, let off, shift to O/D and accelerate again. I dont worry too much about locked shifts with my billet input now though.
