    2019+ ram flex plate

    Hello guys, I don’t have access to my truck in the meantime. Just wanted to ask if all 2019+ 2500 trucks came with a 10 bolt flexplate. Or is there 8 bolts and 10 bolts?

    5th Gen G56 Swap

    Hey Guys, any idea on the electronic side of things when converting a 2021 5th gen from 68rfe to g56? I just toasted the 68 and buying a 4th gen with a g56 is not an option unfortunately. I know how to mount everything mechanical. Wiring and tuning is what concerns me. Is it do-able? You know...

    Trans low line pressure

    2016 ram 2500 68 rfe Trans is slow to build pressure and move at start up. After that the Trans works fine no problems . If I try to move the truck before the pressure builds around 3 or 4 minutes I get a low line pressure code. Please help I can't afford a total rebuild.

    2020 3/4 ton codes everywhere!

    I know it’s a 5th gen but I’ve put 60k miles on it and have had a p0299 code come up since the 8k mile era. Every time I took it to the dealership they said it was the air filter. It needs the sticky strips they said. So they replaced it and a couple weeks later it’s back on again. Take it back...

    68rfe problem maybe valve body

    So I have a 2008 cummins with the 68rfe. I was driving home on county roads after work one day and truck went from fine to shifting weird in an instant. Tried making it to the top of a hill but it was stuck in limp mode and over reving I'm assuming caused transmission fluid to blow out of...

    Noisy 68RFE

    I have a 2018 68RFE in my Dodge Ram 2500 Cummins turbodiesel. It is low mileage and running well; but when decelerating with just a gentle touch of the accelerator, a "shushing" sound that sounds like TV static comes from the transmission. It goes away as soon as any load is applied, or the...

It would go into limp home where it would start in first go direct to forth. It did record a P0868 code, low line pressure. Hoping for a cracked or loose filter...
