New to the site, have a 2021 2500hd with 6.6 gas. Yesterday was turning around in my driveway and heard a bang, then check engine light, trac light, reduced engine power, service parking brake lights all came on. I can run through the gear shift, but it won't engage any gears. When I have it in r or d if I touch the gas it revs up and speedo keeps going up. Looked at shift linkage and it does move, so I'm guessing a serious internal trans issue?? Anyone else have an issue like this? Thank you ,
Update, just pulled code p215b , output shaft speed correlation
Pads from manufacturing who make the brake pads for Gm we’re replaced because of squealing at a crawl
they replaced the pads and it started again after a week
anyone else have this problem
call Gm and waiting for reply
dealer said they wouldn’t do anything about it they replaced like Gm had instructed
Are you Looking to change your headlights and grille on your custom Silverado to the LED HID / signature curtain daytime running lights that High Country’s come with and the bow tie grille ?
Here’s how I did this to my Custom Trailboss ... how to video. Videos nothing special but it’ll give you the pics with notes /video clips that I took so you can convert yours over if your wanting to . Back when I did this conversion I couldn’t find anything online that really shows how you do this so hopefully this helps the next person do this . Takes about 3-4 hours
cost is about $3k for all new oem parts . I got my headlights , wire harness through Gen5DIY.com $2400 and the bow tie grille $580 through gm parts warehouse. Both are great companies I’d fully recommend that made the process really easy .
I’ll list the part numbers too if you wanna research and look for some lower prices if wanna go with used parts or shop around if you wanna that route but don’t forget you’ll still need the headlight harness which is about $250 from Gen5DIY to make all the lights work properly . After you sell your used Custom headlights and grille parts from the conversion you can get back about 1k dropping the cost involved about 2k with new parts.
May ask why not just buy the LT trail boss ., well here’s why I did not .. when I researched this is what I found .,
My Red Custom trail boss came with the halogen lights and the LT Trailboss has the better looking lights that are LED (not too bright though but have a good look to them still) but they are not HID LED which are way brighter unless you buy the midnight black edition trail boss or the high country which #1 I wanted the red trail boss not black , # 2 I wanted HID LED lights not just the LED lights , so I made my own custom set up for a small cost compared to getting a midnight edition Trailboss or high country

Used “like new” condition off my 19’ Custom Trailboss . Truck literally has 8,000 miles on it still so these parts look like the day they did it came off the dealer lot. Asking $450 obo +shipping which I believe is about $65 to most places In the US. I changed my headlights and grille out recently after doing a headlight conversion so I have my grille and headlights that came from the factory for sale now .
