That looks OK.
Mine shows 91.77, neither here or there.
You can track PWM/ TCC operation thru transmission dash.
Just connect (Acquire data) and go for a run.
That way you can see if it's being commanded.

That's OK
The main thing to watch for is On/ Off. That figure won't help if it's not working...

Another thing I thought of is temp. enable.
In the photos there are 2 flags. Maybe temporarily uncheck both, just in case of a faulty sensor/s

The old 3800 is all over by 3000 rpm.

quipt4it trying to keep the trans as close to stock shifting up down as possible as its a daily drive workhorse that i use to tow a trailer here and there etc etc
Trying to avoid a race tune lolll :)

Can the pwm feature be turned on in 11p somewhere so my tcc works ?
You're talking about keeping the stock shift points of the 3800V6 motor, problem is you have a L67. I would advise the factory shift points for that as the starting point. Been that you tow a lot, you should be in power mode, that too will keep the converter unlocked and hold onto 3rd gear longer.

Holding 3rd isn't a race tune. Off boost the L67 isn't that great, especially not in stock form. You'll find with some experimentation that staying in 3rd will actually give better economy in the L67, there is a reason Holden did this.

Immortality if im towing any load on the trailer i normally leave the gearstick in 3rd gear anyways :)

You guys are champions thanks so much.
Loaded up the vt auto settings lot better. I lowered only down the 3-4th shift (under 37% tps) weird tho that my tune says to shift into 4th at 60kph but it dosnt happen to about 70kph. is it cause my down shift for that part is set higher than the upshift ? When i watched the dash in tuner pro i now remember it flicking crazy between 3rd and 4th on tuner pro dash ?
I dash checked in tuner pro and speed in tune is dead on accurate with speedo cluster kmh. The tcc is also engaging at around 80 or 90kph i think it was and is showing in tuner pro on the dash screen as coming on.
Fine tuned some of the air fuel ratios today and it is running pretty dam good all round.

Yes, you will have to lower the downshift speed to be less than the upshift speed.
This will confuse the auto no end.
Glad it's working :D
