    Downshift Issue 2018 Ram 2500 w/68RFE

    I finally purchased a RevMax valve body, new OEM solenoid pack, filter nipple upgrade, thermal bypass, new MOPAR filters, new transmission pan gasket, and OEM transmission fluid. I got it all installed last week and contrary to everything I read on the internet it took 12 quarts of fluid to...

    68RFE Transmission Repair Recommendation in Sacramento, CA Area

    I had a hard downshift issue at 40-45K miles and RAM replaced the valve body under warranty and that resolved the issue. I had hard down shift issues again at about 90K miles and had a shop do a "Transmission Relearn" procedure and that resolved the problem for a while and at 120K miles it did...

    DEF injector

    I wish it could be reset, not sure why it can't. My "Service DEF" warning came on then went off without any stored codes. My buddy had the same issue. His warning came on and went off 4 times and there were never any stored codes. On about the fifth time the warning came on he also got the 50...

    2013 Ram 1500 Check Engine Light - Coolant Sensor

    It is likely the float inside the coolant bottle that has gone bad. I know on the 2500's it is a common problem. You have to change the coolant bottle for a new one. This video will show you how to check the sensor: https://youtu.be/gB0-2aMFcZ0?si=02LREd_sGyeaDW4n But more than likely you'll...

    Service air bag warning repeatedly while driving

    Will the code be stored since the light just keeps going on and off repeatedly/randomly? I have been trouble free since I unhooked and cleaned all of the plugs but the issue had resurfaced. And guess what triggered it? That's right, my vacuum cleaner. I haven't had any issues since June until I...

    Engine hours... what i didnt know...

    As you’re finding out the Idle/Drive meter is terribly inaccurate. In fact mine says I’ve been averaging 1,923 mph covering 148K miles in just 78 hours and I’ve idled the truck 338 hours. When I bought the truck it had 10K miles and the Idle/Drive meter had 168/145 hours respectively. Even if...

    Low coolant light on on CTD

    All of my research shows that the majority of the time it is not the sensor. The OAT coolant creates so much sludge and staining and other, whatever, in the reservoir that the magnetic connection between the sensor and the float is blocked so the float returns to the “low coolant” position...

    Service air bag warning repeatedly while driving

    Yes, that module with the two harnesses is the module. There is a tab that locks like two angled pieces of plastic under the gray bar that you push down and the bar will flip forward to release the bar so you can get the harness out. Repeat for the second harness. Just make sure the batteries...

    service airbag system.. fixed

    Update After getting nowhere with the connectors under the seat in stopping the airbag service message I decided to unbolt the seats and access the airbag module so I could get the part number for it. I disconnected the batteries first and unplugged the two cables from the module and let it...

    Service air bag warning repeatedly while driving

    I have a 2018 Ram 2500 SLT w/ 147K miles on the clock. About 2 months ago I started getting intermittent messages regarding the Service Airbag System. The light would come on and the chime would sound about 5 times per day. Then it got gradually worse as the light and chime would activate about...

    service airbag system.. fixed

    I realize this is an older thread but I’m having the same issue. It was very intermittent last year but now it’s a dozen times per day after detailing the truck the other day. Has anyone just removed the plug and hardwired the two sides together? This is pretty annoying. Every time I clean the...

    Exhaust System Service Required See Dealer

    The message has come and gone over a dozen times. It always goes off after a few key cycles. It went on again today in fact and after I stopped for lunch and left it was off again. There are no stored codes at all which makes it even worse and I can't get the dealer to tell me anything. What...

    Headlight Revolution is a terrible company to deal with.

    I also bought my lights from them. Fair price and fast shipping. Put a stop payment on your credit card, that will resolve the issue.

    Window Up/Down Feature Irritation

    It's been so long since I have had a car w/o auto up/down I find it irritating when it doesn't work. No other vehicle I have owned with the auto up/down feature has this "quirk" so it seems to be a Ram only issue. Probably costs $.005 to do without that problem and the bean counters probably...

    Downshift Issue 2018 Ram 2500 w/68RFE

    I haven't had a chance yet. I stopped using the Tow/Haul feature and I stopped using the Exhaust Brake too. The transmission eventually stopped hard shifting from 5th to 4th and I'm back using the Exhaust Brake for now without any significant issues. It still has a more noticeable downshift but...

    Window Up/Down Feature Irritation

    That’s probably what it is because it happens when my finger slips off. I can’t believe something as simple and innocent as that can cause it to stop working. What a pain in the ****.

    Window Up/Down Feature Irritation

    When my automatic window up/down feature stopped working I easily found the solution in these forums. My issue now is that I have to reset the auto up/down feature about 10 times or more per month? I’ve even had to do it more than one time in a single day. Is anyone else having to repeat this...

    New Member Looking for Advice, I just purchased a 2014 2500 with low 22,000 miles. Unfortunately I wasnt aware that it had 11,400 idle hours!!!!

    My experience with the idle/drive meter is a lot different than yours which makes me trust it even less. In 2019 I bought a 2018 Ram 2500 SLT w/the Cummins motor. It had 10K miles on the clock and the idle/drive meter read 168 Idle hours and 99 Drive hours. Here I am three years later and I've...

    A Lot of Weird Service Suggestions?

    I have gotten four notices to change the spark plugs on my 2018 Ram 2500 SLT with a Cummins motor. Just for $hits and giggles I should schedule the service and see what happens.

    Downshift Issue 2018 Ram 2500 w/68RFE

    This go round I haven't been limiting the transmission very much so as to not cause a learning issue. I will try to see if the dealer will do a relearn of the transmission before I submit myself to a second on my house to pay for a new transmission. I'll find a local diesel transmission...

    Another Transmission Issue - 4th Trip to Dealer Advice...

    Replaced many a bad alternator with another bad alternator. QC seems to be an afterthought these days. Also, just went on a car club run/drive. Fellow had a brand new NAPA battery in his car and when he got to the hotel the car wouldn't start when he went to move it after check-in. Took it to...

    Another Transmission Issue - 4th Trip to Dealer Advice...

    My valve body was replaced after my third trip to the dealer. The truck had 85K miles on the clock. I'm at 110K miles on the clock and I'm going to need another valve body. All of their valve bodies are cast the exact same way so they all have the same inherent problems. They all have the...

    Downshift Issue 2018 Ram 2500 w/68RFE

    I was searching for an answer to this question a while back and asked a question on someone else's thread. I didn't want to resurrect an old thread so I thought I would repost my issue here, update you on what happened, and is happening again. Here is my original post: I have a 2018 Ram 2500...
