trailblazer tow/haul

[bruhaba]

I have an 06 trailblazer and I've seen a couple other threads where a pin can be momentarily grounded to have the PCM use the "performance" shift tables. Anyone know if this is possible for an 06 trailblazer? It's frustrating because the tables look like they are there and calibrated but I can't use them. If there is a way to do this, I would also like to know if there is a way to indicate which mode you are in.

thanks

With the talk of grounding a pin, it sounds very similar to the 'tow button' on the trucks, and more of a rewiring job IMHO.

Have you looked at the configs/histo's in the help section? There might be one there similar to what you are looking for. Just remember sometimes they show up as 'unsupported' until you hook up to the truck.
