I'm going to show my ignorance again lol. I would like to adjust the amount of lockup on the converter to 100% or what ever the safe maximum is. But I am having trouble finding the perimeter to accomplish this feat?

Look at D2903 and D2904... make them both all 100%.
Well this is a little old, but commanding max and min to 100% isn't harsh at all is it? If not I think I'll really like this. Any reason why GM went to a max of 99% and not just straight to 100%?Quote:

As for GM using low minimum % values (in case you wondered about this):
GM tries to apply the TCC "smoothly", which means is slips as its apply ramps up...
a quicker non-slipping apply is better for the TCC;
note that the TCC is applied under almost steady speed non-WOT conditions, so applying it quickly (with no/minimal slip) is fine.
The key is: after any trans changes you make in the tune, be sure to test drive and analyze what happened.
Totally. I'd bumped my 1500 by 20% and I think the 3500 by 30%. 1500 seemed to respond better which is why all 100% sounds appealing for the 3500 which also has a tighter converter so less of a chance of being harsh.
