How to...

Hello. I have a stock 97 CCSB 4x4 w/ auto and 3.55 gears and want to get some baseline times. It also has a Superchips tuner, so I would like to try each position. Anyway, the questions are:

1. Should the truck be manually shifted, or let the transmission do it?

2. If manually shifted, what RPM?

3. Should it be power braked or stomp it at the light change?

Any other advice? Thanks!

Well this is just my opinion but unless the truck isn't doing what you want it to do then just let the tranny do the work. I would only mess with it if you believe it is shifting to early or not down shifting, otherwise the tranny 9 times out of 10 will give the most you can get out of your truck.... if you chose to do it manually I would shift at least 250RPM before you want to shift because of the time it takes for your eyes to register and you to move the gear lever.....and always power brake unless your just blowing the tires off!! again just my opinion......and if you can launch it in 4x4 at the track you won't believe your 60ft time!

shift it manually, you have more holding devices engaged in the transmission than you do in fully automatic

I just let my trans shift itsself -- but ran it with OD off...

always power break to the point that you start to break the tires loose on launch -- you want it to grab, not spin..

and definately launch in 4Hi! Also -- try the trans both ways if you are questioning it -- that way you'll know which is better, just don't redline the engine (although don't the trans have an override if the RPM gets too high?? -- maybe thats just the newer cars...)
