Default M6 to TH400 Swap - Codes Thrown?

So I just realized I need an inspection and the swap caused some codes to pop up. They just keep coming back so I assume they are related to missing pieces of the T56.

P0704 = Clutch Switch Missing
P0801 = Reverse Inhibit Switch Missing
P0803 = Skip Shift Solonoid Missing

I'm pretty sure that these can be deleted like anything else (I hope) but it sucks that I'm going to have to go through the steps to get it back to pass inspection after it is reflashed.

Is this normal after a th400 swap? I hadn't seen this posted in the sticky from what I remembered.

Yes those would be normal codes after a swap I am not sure about the code deletion as I am not a tuner but one solution if you still have the M6 laying around would be to take those items off it and plug them in at least temporarily .

I am not an electronics tech by a long shot ! That being said , you can get a resistor and plug it in to the connectors where those componants were located and that will eliminate the problem . I believe it can be taken care of in the tune but not positive on that !! Back to the resistors I am sure these issues have come up before but I don't know what OHM 's are required !! I am sure there is an electronics guru out there who can tell you about the resistors !!!!!!!!!!!!!!!!!!!!

The tranny is long gone so I hope they can be removed via a tune.

The codes can be turned off. The monitors should be able to be turned off as well!

Back from the dead.

I plugged in the skip shift solenoid but I'm still getting the 1-4 skip shift error code.

Maybe the solenoid needs to be grounded to something? Right now it's plugged into the harness but not threaded into anything.
