torque lock up
Is there anything I can do to my box to get the torque converter to lock up quicker. I dont want to spend to much on the tranny cause I would rather put my money towards a Allison 6 speed.

"when it engages, it should do so with less slippage"
OR "it should be commanded to lock up at a lower road speed"
OR "it should engage with a lower accelerator pedal input" ????
Which one of these are you talking about? Only then can there be an answer.

You can either get a chip or programmer to modify the lockup points or you can manually do it by installing a switch like this one:

The lock up just before overdrive is the one Im talking about. My rig takes to long. The revs are high enough but it seems its waiting for a pre determined speed to be obtained before locking up. If Im holding say 2000 rpm I believe it lock up regardless of speed. this things have enough Ka Hoonas to keep on pulling.

You are right, the Evolution does NOTHING to the torque converter clutch apply point for 3rd gear in the "Tow" program (or "Race" for that matter). I know this for a fact because I have the programming and actual Evolution tunes. There are only two ways to do it. First is by installing a switch that grounds the torque converter clutch solenoid windings causing an always-on, forced TCC apply. This way sucks because it is not automatic. You have to remember to turn it on and off. Granted, there are other ways of doing it that are more automatic than a simple switch, but they are not fool proof.
The other way to do it is with custom tuning. Most of my generic heavy towing tunes (pre-live tuning) will lock the TCC at 25 MPH in 2nd gear and just stay locked through the 3rd gear upshift at a minimum upshift speed of 35 MPH. This prevents lugging, high transmission temps, and sluggish acceleration due to an unlocked converter clutch. It can be done with any power level tune as well....it's not isolated to any particular type of tune.
It's probably not what you wanted to hear since programmers are so expensive....but these are the ways around a "late" TCC apply.
