What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Rocket Man]

Hubby and I got tired of the 06 Sierra Denali's horrible brake performance compared to our 09 Tahoe... So we upgraded the front brakes to the GMT900 style, and now it stops so much better.

I didn't get many pictures because this upgrade has been done by so many of you guys, but I had to have the proof

Nice, thanks for the pics. It makes me feel like I accomplished something, not sure why.

Just did the water pump again, warranty from autozone with oem gaskets. Also flushed out the system while I was there and pressure wash the front of engine

After recently replacing a store brand pump that failed just a couple of months past the 1-year warranty:

Yea, but when they sent me the replacement they sent me another brand, let see how long it lasts. This one actually came with aluminum gasket, but I ended up using oem gaskets.

I hope this one lasts for you. [emoji106][emoji1696]

I've been working on my other cars a lot lately, but I finally got to give my Denali some much needed attention. I fixed the efan wiring (I think) and replaced the accelerator pedal sensor to resolve the P0220 code. Also replaced the rear shocks with the KYB shocks recommended here on the forum and changed out the springs for the Moog heavy duty version. The air shocks have probably been blown since I got the truck 2.5 years ago. This made a huge difference in the ride quality and handling! Now off the have the transmission inspected/serviced for peace of mind. It got up to 215 the last 2 times I drove it. I have not seen it go that high before.

If you haven't already upgrade the transcooler, makes a big difference

I'm definitely interested in that. I was already considering a Tru Cool 40K...I just want to see what's going on first. It always ran cool (180 or under) the last 2 summers and we haven't even hit 100 yet this year. I am concerned to see the transmission gauge hitting 215 already. I have a transmission shop I've used before, but they're a 45 minute drive and we have a baby coming in the next 3 weeks so I'm trying to figure out how to do it without missing any extra work. (Don't worry, there's another baby friendly vehicle in the driveway...I'm not risking her safe transport home!)
