Open Torque Converter Circuit 2006 Tahoe

[LFDavidson]

Code reader is giving a series of error codes having to do with an open circuit to the torque converter and solenoids.. About 7 error codes in all... The transmission was just service two weeks ago.. The check engine light came on and will come on immediately again after resetting.. It appears to be stuck in 3rd all the time when driving and has sluggish start like it is in 3rd... Is there a connector somewhere that may have come loose or was disconnected by the GM dealer and not properly reconnected?

Thanks...

Welcome to the neighborhood!

There isn't a connector like that that would have been messed with during a regular service/flush. However, it IS possible that they flushed it wrong, didn't get the internal filter installed properly or something along those lines. Was it a full service flush?

Yes, it was a 90,000 mile major service...

There is nothing that they "Should" have done that would cause these issues, but since they came up after the service, my guess is that they did something wrong while in there. I would bet that they did not get the filter installed properly or without meaning to they may have disconnected a solenoid somewhere around the valve body. I would definitely take it back to them and make them figure it out.

Thanks for the help.. I ended up taking it back to them.. Bad ignition switch... $325.00 Great design...
