i dont have the original. it's the same base tune any of the 06/07 model tcm's had in them.
im putting it on the dyno tomorrow, so will post the output of the stall unlocked vs locked.

I didnt get a chance to do a unstalled run today as i want to dial in my meth tune. so all the runs in the below graph are with the stall locked in 4th gear.
file ending with 013 was petrol only with flat 12afr's & 495rwhp the other runs are with the meth.
the speed at the bottom is out, but i revved the engine to 6700rpm.
P.S i dont run a trans cooler either.
went to a dyno day today. cooler weather today so the car made 536.6rwhp, exactly 400rwkw once converted.
Awesome.
um. only when you tell it to. standard tcc in a commodore is around the 1800rpm mark so you cant really tell when it's locked or unlocked anyway.
with the larger stall you can definetly feel the difference in the shifts between locked and unlocked. if the tcc is locked you get more a thump into gear, kinda like a manual gearbox. with it unlocked it feels like it glides in. more softer shift. obviously im talking at shifts below the 4000rpm mark here for both.
wot shifts in mine are hard & fast.
I meant in terms of the fluid not overheating (without a cooler).
I'm playing with settings to accomplish a good WOT upshift, quick downshift, and smooth regular upshifts with my Trailblazer 5.3L with Escalade 6L80 and 3.42 gears. Making matters worse, I'm trying to learn some tricks with the traction control as it has an open diff out back.
I started with copy/pasting a Cadillac CTS-V tune in the 1-2, 2-3, 3-4, 4-5, 5-6 WOT upshift categories. It was horrendous....realized there are different clutches and torque converters. With that I found a middle ground and have gone from there. As of now I am using a .2000 in the aforementioned WOT categories and it gives me what I want. Good firm upshifts at WOT and smooth upshifts at partial throttle. Of course there is room to improve, but time is not permitting.
The key is to document what changes you make and to make minor changes to limited categories to monitor your progress/regress.
