Issues After Hydroboost Install GMC 2500HD Duramax

In this video we are sharing a simple solution to a problem. After installing an upgraded hydroboost on this 2007 GMC 2500HD Duramax the truck would not shift out of park. This is a fairly common issue when using the upgraded 2011 system. I came up with a pretty simple solution. Also some bonus footage of this awesome truck.

I rarely leave comments on YouTube, but this deserves one. I just did the hydroboost conversion/upgrade on my 2000 Chevy 1500 and had the exact same issue. Initially I was able to shift out of park and drove to O'Reily….only to get stuck there. Once I unplugged the brake pedal switch, I was able to shift but lost my brake lights. I found this video an hour ago and already fixed my issue! much appreciated my man!

I had the same problem and tweaked the switch you did , but have you had the problem with the cruise control mine is not working and I’m thinking if it’s the next contact on the switch that I might need to tweak.

Great video, I had the same issue, tried your trick and it worked like a charm. The only issue I had was I inadvertently adjusted the contact for the brake lights to where my brake lights didn’t work and therefore my trailer brakes wouldn’t engage when I depressed my brake pedal…so a word to those who end up doing this, be careful not to adjust the brake contact when your adjusting the interlock.

You saved me, I had it all back together and wouldn’t go out of park until I found your video, thanks!

2002 chevy Silverado 2500 hd 4×4 6.0 just checked the going into drive issue, and it seemed to work just fine but the break light was on when I go out of the truck!! I tapped the break pedal and it went out. so maybe I will order a new one instead of removing for the 4th time and reworking the old one! is there a newer version I should get??

@meademods6024 says:

and the fucken break clip is a real pain in the ass!!!!

@meademods6024 says:

FUCK AUTO ZONE!!!!!!! Hydro boost do not buy!!!!!!

@meademods6024 says:

I worked the pedal back n forth and pulled back hard and the lights turned off. so I'm wondering if I need to bend the pin like you did to get the break light to turn off?? I have not tried to drive it yet!

@meademods6024 says:

installed the new hydroboost and it bolts right on. BUT!! the break light is staying on ???
