What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Yeah climbed under there tonight to check out the parking brake switch.

It should look something like this if I'm not mistaken.

That’s the one. Yeah climbed under there tonight to check out the parking brake switch. It sure is buried deep in there. Also can’t believe how much lint is stuck under there. That may be why it is not working. I’ll tear that sht part this weekend and vacuum the hell out of that area and try clean up the switch or at least test it.

I would use some compressed air to blow it all out and then hit it with some contact cleaner. if you have any maf cleaner sitting around it will do the same thing as contact cleaner

I have a feeling I'm going to need to do a rebuild/upgrade on mine not long after the cam and supercharger go on.
Last couple weeks it's been giving me a weird little RPM jump while cruising going from 5th to 6th as if it were slipping somehow between the gears.

Makes me want to order the 4-5-6 sonnax hd piston kit... lol

Started thinking about it, and tossed in some 4 5 6 steels too.
New apply area, seems like a good idea...

More $$$!

Figure I'm making more power than stock.
I did this for boat hauling...

Most of that boat hauling will be in 4 5 6

It's always that one thing i didn't do while i was in there... lol
