Code P0741 And Sluggish Running

I went to trade in my camper for another and had a 6 hour round trip to do so. The truck, an 06 Sierra V8 - 5.3, drove just fine on the way up, but 2 hours into my return it started to get very sluggish and struggled to maintain 60 on a flat highway. Close to home, the engine light came on. After unhooking the camper, I took it to Autozone and had the code pulled. It was P0741. I then took it to a trusted transmission shop and had them look it over. They went over it for about an hour, test drove it, but didn't find a thing (didn't charge me, either!). They said it might have just been a slip, or maybe the torque converter is going bad and needs replaced. They also checked for any air flow problems just in case that's what caused the power loss. Any thoughts? Camping 8 hours away in 3 weeks and would like to have peace of mind. Also, my camper is 4300 lbs and is only 500 more than the previous.

      Transmission Temperature Hitting 220s

      By DustMcGrath · Posted

      First of all sorry, I know there are a ton of transmission temperature threads...   My truck is a 2025 LZ0 High (10l89 10-speed) High Country with NHT max trailering package. The NHT package is supposed to have "enhanced cooling."   Normally the trans temp sits around 200. It seems like with any real stress it quickly jumps into the 220s (for example climbing a grade unloaded at lower speeds). I haven't towed much with this truck, but I'm concerned if it gets this hot unloaded.    I've tried a few different things to keep the temps down (tow/haul mode, sport mode, low range when that makes sense) and nothing seems to affect it.    I'm curious if others are the same behavior or if anyone has found techniques to keep the temps down. It seems like it just can't handle reduced airflow at lower speeds, even with relatively light loading.    Thanks!

      I'm at 105,000 miles on my baby Duramax. No issues yet. I hit 31 mpg's traveling through hilly terrain to a project in Colorado. I will buy another 3.0. I'm not concerned.

      Which 2027 engine will you choose?

      By cautious optimist · Posted

      I'm glad you have 14,000 trouble free miles. Frankly though, that's a really low bar. A bare minimum of 80,000 trouble free miles as the norm (rare exceptions always exist) across the whole model year should be a starting point. Good maintenance habits should push these past the 100,000 mile mark with only the most minor of issues. Let's hope GM truly leveled up the quality game with these new engines and exploding engines under 50,000 miles are gone.

      This is exactly the reason our EV has consumed so much of my driving. I don't want to fire up a cold diesel or gas engine just to drive 2 miles up to the store. It's arguably terrible for an engine. If I'm not driving at least 10 miles and don't need to do truck things, the truck stays parked.   Enter the EV. It's immediately heating or cooling the cabin as needed (heat pump). An engine doesn't need to warm up or be driven gently. I can tear off in it with ZERO guilt. Move the car 1/4 mile from store to store and not think "gee, I'm short-cycling a lukewarm engine".   It doesn't idle in a drive-through. Doesn't idle at stop lights. (OK, neither would the diesel, if I let stop-start have its way, but I don't).   Even moving it out of the garage to wash it... HA! It doesn't need to be started just to move 40 feet. I have cars that I will actually put in neutral and push (no start) in/out of the garage or shop if they absolutely HAVE to be moved. My nice Camaros.
