    Another p0456

    First got this code two years ago randomly and cleared it with the handheld scanner. Figured I didn’t get the gas cap tight or something. It came back a couple times in the past year, and cleared it. Three months ago it is now persistent and popping up again every 4-5 cold starts— once a week...

    52 gallon gasoline tank 2016 LB 2500

    I read that the 2022 2500 and 3500 long beds have an option for a 52 gallon gasoline tank. Anyone have an idea if this new tank would fit a long bed 2016 2500? Part numbers between the years don’t seem to match up— for the 32 gallon tanks. I’m wondering how similar the chassis are between the...

    Front diff change

    Changed the front diff after 4 years and 23k miles in sunny Northern Cali because I know it will get a lot of 4wd this winter in New England. This is a 6.4 2500 Cc lb. The fluid appeared good, except for gooey crap sitting in the bottom of the differential, almost like additives dropped out of...

    Gearshift cable tightening?

    Anyone know procedure to tighten it up some. My transmission started to get some vibration after installing the aftermarket pan at speeds between 50-70mph. When I put downward pressure on the shift lever coming out of the steering column the vibration goes away. Leads me to think if I tighten it...

    60-70mph, 1800-2000 rpm whine

    Truck has been whining, kind of sounds like a vacuum leak, when you press the gas slightly to cruise on freeway. It sounds like it’s coming from the engine bay. I was reading about this issue and a guy on another forum said to adjust the shift column while cruising and it will go away. I push...

    Transmission service 66rfe

    I broke down and ordered a Maghytec 45/545 transmission pan with the step, 2 quarts over stock. Also purchase the ATS thermal bypass delete, which I’m hoping will bring my trans temps down 20-30 degrees. I got a great deal from Walmart on a 12 quart pack of supertech Atf4 for 4.44 per quart...

    Delvac 1 5w40

    Changed out the pennzoil srt 0w40 to Mobil delvac 1 esp 5w40 CK-4/SN. No lights, no codes, runs well. I like the higher TBN, anti wear additives, flash point, etc of the HDEO. Seems to idle when oil fully hot around 32 psi and hit 56-57psi at 3/4 throttle, which is maybe 1-2 psi higher. It is...

    Blue Smoke Startup

    It smoked at startup 6-7 times during the first 1500 miles. I changed the oil, kept with the SRT 0w40 pennzoil at 2500 miles. Just checked my oil tonight and it was a quart low, i am at 5000 miles now. I added 3/4 of a quart, started in up, completely level in my garage, and a ton of blue smoke...
