  1. 2019+ Powertrain
    Hello, As the title states, I have a 2020 ram 2500 with a 6.7L Cummins with the 68 RFE transmission, and I am hearing the very distinct clunking sound going into reverse gear. Only, dealership states that there is no issue and refuses to fix it however I have had multiple independent...
  2. 2019+ Powertrain
    Recently sold my built 07 5.9 with a g56 and went bought a 2020 ram 2500 Laramie with 106,000 for a really good price. I noticed the transmission shifted hard when going from 2-3 and 3-4 gears. After about a week of having the truck I noticed a ticking noise at idle coming from the transmission...

    Not sure if my trans grenaded or blew a gasket out. Was driving on free way going about 80+ mph when all of a sudden I hear a pop, and truck starts vibrating really bad (almost like a U-joint just failed) pulled over immediately looked under neath to see my trans was pissing out trans fluid from...

    Hi all I give a quick run down on the lead up to my tranny issues. Basically stock, truck has a raceme on it. Truck was dead after not driving for a few weeks (batteries real old). I tried to jump start it 4 or 5 times off a smaller battery and didn't work. Got a neighbor to jump with his old...

    I got a couple of RaceMe tuner/Trans questions. 1- How do these guys change the idle sounds with their RaceMe Ultra tuner? 2- I have the 68RFE and my RaceMe Ultra is not showing any of the parameters or monitoring information. I can see current gear which shows -1 for reverse, 0 for park then...

    Researching a new 68rfe trans to be saving toward, I’ve seen a lot of guys worshipping revmax but 47re-wise always heard suncoast was the best option. I don’t have massive power goals, but she works so I’ll be going with the highest “stage” of either brand. So for the highest power options what...

    After searching endlessly on every CTD related forum I haven’t come up with any explanation for this. 2014 Ram 3500 slt, crew cab, 4x4 with the 6.7, 68rfe, and auto transfer case. On acceleration 0-10, everything is okay It feels like it shifts at around 10-15mph and then holds the gear until...

    I did the column to console shifter mod on my 2014 Mega Cab, and now I cant shift out of park. I copy and pasted the part numbers and have verified that I got the correct ones. I'm not sure if theres something I should be troubleshooting, but I've tried re routing the cable and I was able to...
  10. 4th Gen Engine/Transmission CUSTOM TUNING
    Fate be known, I will be replacing my 68RFE in the next year. After a lot of research, it seems everyone claims to have the best options on their website with equal reviews to match their claim. At this point I’m lost as to what would be my most cost effective option and need some real world...

    New to the Forum! I have a 2017 Ram 2500 6.7 with the 68RFE. Made it a few miles from my house and my truck randomly dropped all the way down to 1st gear. Now it’s stuck in 1st. I tried shifting with the switch to change the gears and it won’t do anything. Has a 115K miles on it. Deleted and...

    No check engine lights trans shifts fine. Issue is getting on interstate getting up to speed trans will shift into 5th then 5h over drive back to 5th (I let off throttle) will go back into 5th over drive and go to 6th and do same if giving it to much throttle. ( this is normal driving throttle...

    My other half has a 2013 Megacab 2500, automatic, with the 68RFe. We bought it brand new off the lot, it’s got roughly 120k on it now. We’ve already rebuilt the trans twice, and it’s starting to sound/feel like we may be in for another round soon. He’s itching to do an Allison swap so badly. He...

    2018 2500 AEV Prospector XL Adding ATS stage 2 turbo along with a banks monster ram intake elbow, everything else on the engine and trans is stock. You guys think the 68RFE can reliably deal with the extra torque? ATS says it’s + 90 lb/ft of torque over stock 🤔 also if anyone has these parts in...

    Truck in sig, 2012 w 68RFE 30%overs, deleted and studded, 6 inch lift on 37's (I know, very very impractical, changing that soon as possible). I hotshot in the ND Bakken with 3.42 axle ratio and a 40' GN trailer (8500lbs). My problems mainly lie on a certain highway (ND22), where there are 3...

    I have a 2008 Dodge Ram 3500 6.7 cummins with the 68RFE Hoping Tansengineer is still here! Tried to PM him but system would not let me since I am new. I just had a complete rebuild on my transmission (valve body is a year older than the rest since it was just replaced just before) when the...

    I’ve been have a code pop up p 0868 for low transmission line pressure. It mostly happens when I pulling my camper going up a grade. I lose power even when I punch it it doesn’t down shift nor does it rev up so it just doesn’t go anywhere like it’s going into a limp mode so it will climb the...

    2011 Ram 2500 4x4 SRW, 68RFE, Manual TC, RaceMe Ultra, 135,xxx miles Driving down the highway, transfer case started making noise. First grinding, then popping and grinding. Presumably the chain or sprockets(s) broke. Pulled front driveshaft and kept driving for 400 miles until I got home...
