Default TC Lockup

Anyone figure how to lock up the TC when you hit third gear? IS it possible? Thanks, James. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

I just use a switch tied in with the TC lockup controls on the PCM... I hit 3rd and I flip the switch... though I'm sure there's a way to do it via LS1 Edit... just haven't tried

You can lock it via ls1 edit in any gear pretty much anytime you want.

Think ideally you would want to lock it a little ways into 3rd gear instead of directly on or after the shift. It'll feel like its fallen on it face if it locks as soon as you hit 3rd cause your getting rid of any torque mulitplication you might still be recieving.

Dustin:

Raise your low TPS 2-3 shift points by 3-4 mph. This cures the falling on its face and allows a low lock-up speed.

Yea but is he talking normal driving or wot throttle at the track?? I would think at wot immediate 3rd gear lock up would hurt your acceleration.
