I noticed this morning my 2022 6.6 L Duramax was a hair over 210 and stayed there the whole time this was the first time I ever noticed that and also I noticed and this may sound weird but I used to get the smell of DEF from the exhaust and now I get the smell of diesel from the exhaust. Also, the first five minutes of driving I think it went in the region and it was smoking pretty bad at idle at a red light. I don’t know maybe I’m just paranoid. just seemed weird to me. I just get a DEF smell from the exhaust , but now I had a hard diesel smell. Maybe the thermostat got stuck or something I’m not sure. Any ideas?

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I have never seen GM instructions for the other trucks as per the HD with the 6 speed or the half tons but had got the impression that the HD trucks with the 6 speed were not having the same problem that the 10 speed and pan presented. Also video that I have seen of the HD 10 speed with the gas engine starting in 2024 model year showed that it was a real struggle to even make it work when pulling down hard on the exhaust after undoing the exhaust hanger bracket on the side of the transmission as after all there is little room for the pipe to even go down behind the Y joint as it soon would hit a frame cross member. Also that they had tried just like I did with the gasket off and no way was that pan coming out any way they tried to manipulate the pan. From that as well as the local transmission shop talking about the pain in the rear issue, I was not expecting my pan to come out because GM shows it was not even intended to come out without dealing with the exhaust piping.    It would be nice to claim, here's what you do and its easy to remove the pan guaranteed on any HD truck with the gas 10 speed but dollars to donuts the next guy trying what I did would not have the same luck as the exhaust was just manufactured slightly different and be pissed off at my claim that the pan comes out with no issue. Its more of a try and see if your particular truck might work like mine did .... or not !.

      Sorry I didn't see this until now, but it works on both the 6 speed and 10 speeds, as well as all the half tons too.

      Engine vibration after motor mount replacement.

      By 1998sleaze · Posted

      Hello, I have a 2018 GMC Sierra 1500 that I recently changed both motor mounts on due to the driver's side being blown out. After replacement I seem to have a steady vibration that I can feel in the pedals and the back of the seat. At this point I'm convinced that the aftermarket "Anchor" branded mounts I used are not performing as well as OE, the only real reason I ended up using the mounts in question was because my local dealers were out a few months to get a Driver's side mount. I've tried "Neutralizing" the mounts according to the motor mount TSB published for these truck to no avail. My trans mount is also in great shape and seems to be absorbing vibrations swimmingly. As far as I can tell there is no issues idling, my idle RPM is steady and I've recently put GM plugs and wires on, however, I have not cleaned the throttle body or intake valves. Any one else have a similar experience with aftermarket mounts? Patience certainly is a virtue that I wish I exercised here. Thank you!
