Why would you want to do this? Your transmission is not designed to handle the additional heat generated by a torque converter that doesn't lock up. You will probably fry the tranny within a few thousand miles. Also, the PCM will notice that the converter isn't locked and it will put the tranny into limp mode. It will shift like a jackhammer until you reset the PCM, and then it will do it all over again.

Good point andym, I wasn't under the impression MiracleMax wanted to stop it from locking up permanently. Only for test reasons based on his older thread.
It is also bad if you lock it manually and keep it locked all the time, while shifting up and down the computer unlocks that clutch just briefly to soften them shifts.
If this is for testing I'd also connect a small LED light to the computer side so you can watch what the computer is doing at any given time.
