    How do I disable the 6R80 in PCM to use separate trans controller?

    I have a 2012 Coyote with Whipple and 6R80 in a '33 Ford roadster. I'm using the PCM that came from the donor car for engine management, but I want use use a US Shift Quick 6 to control the 6R80 built by Performance Automatic. The Quick 6 installation instructions state that the transmission controls in the PCM should be disabled. If anyone can instruct me on how to do this, I will be most appreciative.

    How come you do not want to use the factory 6R logic its very good but the quick 6 is good as well have used both if you are trying to get rid of sensors and other modules in the network I understand why you would not want to use the factory 6R logic? It does talks to a range of modules to operate at 100% but you can also disable a lot of those modules and have them not be apart of the algorithm.

    You are going to have to play with it a little as well as disable a lot of stuff I do know from experience you can piggy back the quick 6 to some extent into the copperhead PCM to give some data and keep the auto PCM happy.

    Post your original read and I can assist you in your project to get the trans section right or deleted.

    Have you considered going to a control pack manual strategy or manual OE? You can DM me if you don't want to post your read.

    If you haven?t gotten the results you are looking for I can help. Post a stock read and I?ll take a look to make sure you have the proper setting selected to disable the auto transmission logic. There are quite a few parameters that play a role in auto vs manual vehicles that have to be setup correctly.
