TC Locked status PID in 6R80 Service Manual

Hi Saeb,
Found this PID list on the 6R80 trans Service Manual. Is the TCC_OSC# (Output State Control of Torque Converter) a possible find for Ultraguage by any chance?
I'm a 2012 BT50.
Cheers.

Can do but you will have to remember what equals what.
1. Also keep in mind that it is what is being commanded by the ECU so may not be actual.
2. Don't assume that there will be data output, just because it is in a manual does not mean the PID will output data.
3. Also unsure if you will see an actual change as factory tunes never completely lock, it is variable across the whole load/rpm range.
We have to show this as raw data, be sure you copy everything exactly as per the image below. If you do not see 00 with ignition on then you have not copied it exactly.
00 = Normal Operation
01 = Forced Unlock
02 = Forced Lock
03 = Forced Fast Lock

Thanks, Stewart.
I've had the transmission tuned and so the TC locks in all gears except 1st and 2nd so finally rid of all the slipping.
The TCC_OSC# is probably redundant for me now with the tune. As you say, what's commanded and what's going on are two different things.
Perhaps a more accurate indication of "what's going on" would be TC_SLIPACT (Torque Converter Slip Actual)?
Thanks for you all efforts.

I believe slip is already on the calc.

I’d like to know if the TC_SLPDSD can be utilised?
I was told to review that vs actual is a good way to determine state of the transmission and converter?

A request may not be actual. You may use requested against actual to diagnose an issue.
Why not just use "Trans Measured Slip Across Torque Convertor" PID in the PID calculator? Which is Measured as engine speed minus turbine shaft speed.
These transmission do not just lock and unlock. There is always some slip and the lockup maps are variable across the load and rpm range.
