Submitting a new thread to try to diagnose an intermittent TCC enable command. I have all the available channels related to torque converter control displaying in my scanner channel list.
My ecm will not apply the tcc even though I will be driving well within its enabled parameters (speed, tps, etc)
This is an intermittent issue, meaning different drive cycles it will apply the converter like its supposed to, and other times it wont. I can always apply it manually via the special functions in the scanner. Usually after I write a new file it will be happy and apply, but after a dozen or so drive cycles it "learns" to not apply. Ive changed most every table in the torque converter tab within the Transmission side of the editor, to no avail.
I am somewhat convinced there is something going on in the background that the ecm is learning to not apply the tcc, if anybody has heard of anything like this and would care to share that would be nice.
This is a turbo 5.3/6l90e application, it makes power pretty low in the powerband. Might something in the virtual torque tables affect how the trans applies the tcc?

I manually applied the converter in the log posted above
