    Mystery battery drain 2018 Ram 3500 pickup/Cummins 6.7/Aisin

    At first this seemed to be a bed light that would turn on spontaneously, and we disconnected the LED circuit connections at the light curing that part. But the dying battery problem either continued or resumed (thought cured for a few weeks but don’t know if “tested” so am unsure of that)...

    Hot weather Aisin limp home mode

    See archived thread “Aisin limp home mode symptom in hot weather CONTINUED”. After the transmission module was replaced a couple of years ago, this seemed to happen less often. I also had our dealer’s mechanic confirm that the connector at the back of the driver side wheel well was in good...

    2018 3500 8.5” radio failures (hot weather??)

    Our large central display (Ram calls it the “radio”) failed after six years and was replaced under extended warranty recently. From the day it was replaced, it has periodically “gone dark” and simultaneously the related buttons and knobs fail to control functions, such as climate or audio...

    CJC Offroad 4th gen 2500 air dam delete/skid plate sturdiness

    I’ve torn off one corner of the factory air dam in deep snow once, replaced fasteners but would like to delete the plastic air dam and replace with something that will tolerate bucking a bit of bumper-deep snow without damage. Has someone installed the CJC Offroad “skid plate” aluminum...

    8-foot wide self-powered snowblower for 2018 3500 HD dually Ram?

    Is there a self-motorized 96 inch wide snow blower that can be used, mounted similarly to a plow but not needing the “push” strength that a plow needs, for our 2018 3500 dually 6.7 Cummins/Aisin transmission truck? It has ample charging capacity for lights or controls (440 amps), but no snow...

    Flanged locking lug nuts for duallies-do they exist?

    Have been unable to find locking washer-type lug nuts for our 2018 Ram 3500 HD dually in a lot of searching this morning. Can anyone point to some that are available? Thanks

    2018 6.7 Cummins 2 quart engine oil overfill

    I took 2-1/2 gal plus a gallon of my chosen Rotella T6 5W40 to our dealer for an oil change, and got no oil back. Wasn't too concerned until dipstick reading high at home, about the distance of the "normal" range above the top of that range. Seems likely the oil change tech just used all the...

    Edge Insight CTS3: does Turbo Timer require a separate unit and manifold temp sensor?

    I'm planning to add the monitoring-only CTS3 to our 2018 Ram 3500HD pickup, and include the Turbo Timer. I thought from reading about it that this required adding the Turbo Timer accessory, and installing a sensor in the exhaust manifold, using a Basic Starter Kit to daisy chain the input to...

    Aisin "limp home" symptom in hot weather CONTINUED

    See the archived 4th Gen forum thread "Aisin "limp home" symptom under load in hot weather" for reference. Again had similar EVIC messages towing/hauling camper in hot summer weather, like "4WD system unavailable". Do not remember having it stick in the 4th gear only limp home mode this year...

    Best diagnostic scanner for 4th gen Cummins 3500?

    I have an Aisin transmission diagnostic question related to the "4th gear only" Limp Mode occurring when heavy hauling in hot weather, 2018 Ram 3500 Cummins 6.7 with Aisin. It has been diagnosed and repaired once using codes read by my dealer right after the truck was brought in, displaying the...

    Aisin "limp home" symptom under load in hot weather

    2018 Ram 3500 pickup crew cab, long bed, DRW, Cummins with Aisin transmission. My previous thread on this problem has disappeared, perhaps because it got too old/too long since last post. This is the follow up now that there has been a diagnosis and warranty repair done. In brief, symptom: In...

    Variations in "dry" brake fluid conductivity affecting tester results

    In TDR issue 105, Moses Ludel in "The Long Haul" recommends a brake fluid moisture content tester that he uses to help decide when to flush and replace brake fluid. This type of tester measures fluid conductivity (or the inverse, electrical resistance), the conductivity increasing (resistance...
