Battery disconnect method -
Can do a hard system wide reset by connecting a jumper between the disconnected batt cables. Go into cab and turn on every switch. Lights, heater/ac fan (on high), dome lights, wiper/washers, and the ignition key switch. I mean EVERYTHING. Let set 30 minutes. This saps all residual electrical charge from the entire electrical system. PCM,ECM, TCM, and any other M's will reset to factory default.
Remember to turn EVERYTHING back to off BEFORE reconnecting battery.

I have a 2006 chevy 2500hd with the 8.1 engine and allison tranny. As of now ive determined it's stuck in limp mode. I did the battery cable trick and such but can't get it out of limp mode. From all the research its pointing towards the TCM being faulty. Is there a way to tell for certain that the TCM is bad? Thank you

Hi! Will this work on a 2011 Chevy Equinox

How about the following, a possible TCM issue? 2006 GMC Envoy XL Denali 5.3L 2WD. Rare occasions, start SUV normally, shift to D or 3, Shift indicator doesn't move, but car drives, slowly but gains normal speeds, but speedometer does not register. drive to destination, park SUV for 30 min. start SUV and all is normal. Drive SUV for 3 or 4 days no problems. 5th day, the above happens. I should add, the SUV has 230K on it.

What about a 1995 GMC Vantura

[@jamescarbone4857]

Would this go back as far as a 2005 3.5 malibu?

Hi, the methods we gave in the video should work for most, if not all Chevy models. However, depending on your model and the type of TCM it has, you may need to do some trial and error using the methods.

Changed my 2010 Chevy impala LT TCM and when getting in the car with it all started up. The shifter knob is stuck and won’t allow me to put it in drive or reverse, anything. Is there a reset program i need to go through?

[@dallasmckinney1706]

There should be a shift release button around your shifter handle if not it's up under the plastic ,but when u find it push down and you should be able to put your car in gear

Pull the plugs out of the tcm and check each pin to see if there are any that have slid down in the connector. If so pop it apart and push them back up in to position.
