    Looking to buy third gen, what should I know?

    Good Lord! I respect that decision though im 90% sure you're probably the only person in the world to trade in a $70k truck for a high-mileage old dodge LOL. That being said, a few things to note: 2006-2008 1500 (3rd gen) - great truck, harsh ride compared to f150 of the same year. Plain...

    MDS and Lifter Noise

    I have a 2007 5.7 with mds. Mine has 146k on it. Since I bought the truck it has always made a lot more noise in 4 cyl mode with mds engaged. As far as the oil viscosity goes, is a check engine light on? If not i would try a different scanner. I bought 2 scanners and one says incorrect oil...

    Double din upgrade

    I'm going to be purchasing a double din Eonon radio for my 2007 truck. In there right now is the REF radio. Im also buying the center stack thing to fit the double din. Only like 100 bucks so its worth it imo. Just wondering how the wiring will connect. Is there a harness I need to buy...

    5.7 Engine turns over BUT NO START

    I have a 5.7. Ill start with that. I was having an issue with the crankshaft position sensor. The truck would randomly stall and sometimes not start at all. I replaced the crank sensor and same thing happened. I figured out that if I unplugged the ckp sensor, the truck would start but it would...

    Is it bad to use the transmission to decelerate

    Yes I know you can engine brake by downshifting a manual. Ive done it. But I wasnt aure if it was bad for the clutch bands on the automatic. I have D-2-1. TOW/HAUL will kill 5th, O/D OFF will bring me down to 3rd and then i can use 2 and 1 to slow down even more. I just wasn't sure if it was bad...

    OD Off/ tow haul mode

    Ok im not sure whats going on here... could just be my morning brain not cooperating. So if you dont touch anything and then cruise all the sudden it will be in tow/haul, or od off? And if you actually do push the botton it won't do it? Sent from my SM-N975U1 using Tapatalk

    Misfire cyl 8 after crankshaft position sensor and connector replacement

    2007 5.7 1500 throwing a code for cyl 8 misfire. About a week ago the truck stalled out of no where and threw a code for ckp sensor malfunction. Replaced the sensor and same thing. I took the connector off and saw that the red wire was shorting out against the block. So i replaced the connector...

    P1128 and P1129

    When it misfired it went from about 2k rpm to 1k rpm only for a second. It was a sudden loss of power and it did it a few times. So i put it in tow haul and then od off and it still did it, it went from like 3k cruising rpms, down to about 2k rpms and jumped back up. So i floored it and the...

    P1128 and P1129

    Driving home from a 80 or so mile drive the truck started to misfire at about 70mph with cruise control on. So i slowed down to 50ish and floored it to 85 and the problem didn't come back till I got like 5 minutes from home. And same thing. So I floored it again from like 30 and went to 95 or so...

    And you have the HEMI or Cummins? If you have the HEMI you should have the 545rfe with either 21 or 23 pin Sent from my SM-N975U1 using Tapatalk

    Diff Oil

    In the front dif use 75w-90 oil without any additive. In the rear use 75w-140 with an additive. I used a copper sealant on the cover after using a razor blade and carburetor cleaner (brake parts cleaner works too) to get the old sealant off the diff pumpkin and cover. Each takes a little more...

    2013 4.7L Acts Like A CVT

    That’s normal. Typically in my truck (545RFE) 3rd gear is very wide. It sounds like a CVT sometimes, almost to the point where i want to punch the gas a little to get it to downshift. It is normal. Stupid imo, but normal Sent from my iPad using Tapatalk

    2007 ram 1500 5.7 blew up/ want to swap

    The 2007 2500 will likely be the best choice as it is the exact same engine. The 2005 does not have MDS but I think, and don't quote me on this, but I think the 2007 2500 does. I'd do a little research on that, make sure it does. Thatd probably be your best bet. How did your engine blow up? I...
