Ok i have lauched a few times in OD, so i think i have the launching down pat. And a few recommended to run the sy in D. but if i lock up the TC do i have to shift manually? Previous owner said to put in D and launch from 2nd cause the truck will automatically start off in 1st. Is this true?

You want to launch your truck in D as there is more line pressure in D and it will be easier on your transmission. I flip my manual lockup switch soon as I pre stage at the track. The truck won't lock the converter until it shifts into second gear BTW. Stage, launch and you're on your way to shaving .2 off your ET easy (my bud with a loose 9/11 picks up .5 when he locks his TC :eek:). After I go through the traps at the end of the track, I flip my lockup switch off and slap the shifter into OD so that I don't annhilate the overrun clutches. My manual lockup switch is located right above my headlight switch so that I can get to it easily. Don't sound too bad until you try to remember to do it all at the track... HTH's

I put my lock up switch right beside my seat.I drilled a hole in the side of the sill plate and installed a toggle switch.It works good for me,and the s10 sill plates are not rare :wink:

Here's another tip (if you didn't already know): you don't have the depress the button on the shifter to shift the transmission from D to OD. All you have to do is push the shifter forward and it will go into OD from D... HTH's

It's nothing special, any single pole/single throw switch will work. Radio Shack has plain jane ones or you can get a lighted one from Autozone or the like. In fact last time I was in the automotive section at Walmart, they had them too... I got mine through Jeg's a few years ago (made by Painless). The nice thing about the lighted switch is that it will light up when the converter locks when you are cruising. Makes it easy to see that it is operating correctly. HTH's
