    ROUGH starts on cold starts?

    Just started experiencing this issue. 20k miles. Been happening about 2 weeks. Only on cold starts, I get a rough idle, goes away after about 10-20 seconds. Never again rest of day. Next morning, repeat. No CEL.

    Idle Surging when put into reverse

    Just started experiencing this. Though it has nothing to do with the transmission for me. I echo the folks noting cold start on hot days. Under those conditions, I;m now idling rough and almost stalling. Once truck is warm, no issues. Vacuum leak? Injector? PCM? If there is a fix for this...

    TSB #24-001-20 A/C Fix. Has anyone had it done yet? Plus are you happy with the results?

    Ok you may have something else going, low refrigerant, not sure. When I did the clamp and then the eventual valve, I went from 52 to 42. Huge improvement. If you’re staying at 50 open or closed something is amiss.

    Thanks for posting vent temps. You definitely appear to have heater core heat bleeding into your AC.

    TFW my Polaris Ranger has a higher payload than my Ram

    Funny comparison for sure. You can more comfortably overload the Polaris as you won't be going 75+MPH down I-95 - at least I don't think you will.

    TSB #24-001-20 A/C Fix. Has anyone had it done yet? Plus are you happy with the results?

    Thanks for posting numbers and not just "it's good" - that is a significant improvement in vent temps from the 50's.

    TSB #24-001-20 A/C Fix. Has anyone had it done yet? Plus are you happy with the results?

    Ended up doing my own TSB - the heater core shut off valve. Vent temps in this humidity down from 52 to 42. Huge improvement. It feels like a totally new truck in the summer. Folks in the "How's your 2021 AC" thread were depressing me. They have the updated HVAC housing that the TSB installs...

    Some Real World MPG Numbers

    Boss Mode MPG's. I'll take it for an old school pushrod V8. I really love the Toyota Tundra which is a truck I almost bought instead of the Ram. It's funny getting more highway range with my 26 gallon tank than a tundra with a 38 gallon.

    TSB #24-001-20 A/C Fix. Has anyone had it done yet? Plus are you happy with the results?

    I also have a pretty good dealer, but my main reason for not proceeding with the TSB is so many folks reporting marginal gains (3-5 degree improvement vs the hack which is 8-10 degrees for most people on the drivers side). Would you be willing to post pre and post TSB driver and passenger...

    Gear Switch 3.21 to 3.92

    What is the size of your trailer? Don't be afraid to operate at the max of the 3.21 for towing (8k lbs range). The 3.21 is very underrated by the manufacturer. You have a gear for gear mechanical advantage over a Toyota Tundra with 4.10's with your 3.21 thanks to the 8 speed. If you're much more...

    TSB #24-001-20 A/C Fix. Has anyone had it done yet? Plus are you happy with the results?

    I'm a bit alarmed that 2 folks who've had the TSB done are reporting temps in the high 40's low 50's still. I haven't had the TSB. My AC blows ~52. If I pinch shut the heater hose I can get it down to 42. Much better temperature and a ten degree swing. I would expect folks that have the TSB...

    Air conditioning Hack

    Thinking I'm finally just going to do the hack. I don't trust any of my local dealers to tear apart the dash and put back together correctly. Then there are folks reporting that it's only marginally better after the TSB. Just ordered all the parts. Will see if I can get away with 70/80% closed...

    12.0 GPS Navigation Location Wrong

    Following the thread. Exact same thing happening to me in my 19 with 8.4 nav.

    Reproducible rough start condition, starting after short run time

    Agree it sounds like something with the oil, but I don't think it's filter/oil related. This seems like a Hemi specific issue. I've never observed this across all the other vehicles I've owned. It's unusual in how specific the issue is (occurs only on a followup start after a short run). I would...

    Reproducible rough start condition, starting after short run time

    Has anyone else experienced this issue? Truck will start perfect even after sitting up to a week. You run it a short time (under 20-30 seconds), say to move out of the way of another car in the driveway. Then, when you restart the vehicle later that day, it's loud/rough like it is suddenly oil...
