    I have a 2017 ram 3500 tradesman. 4x4. So yesterday I hit a really bad washboard on a gravel road. Check engine light, abs light, and traction control light all came on, as well as truck going into limp mode. I was pulling up to my job, so I killed the truck and let it sit while I worked. After...

    2013 ram 2500 6.7 Cummins stock 252,000 miles. Maintenance oil every 10k miles transmission 75k for the first and every 25k since had no issues. Drove it like a grand paw to say.

    So I have 2008 Ram 2500 Megacab with a 6.7 Cummins and 68RFE with 227,000 miles. In the past the torque converter and valve body had supposedly been replaced if it may have something to do with that. I have two issues that are probably related. The truck will go into limp mode if I accelerate...

    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...

    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...

    I have a 2016 Ram 2500 Laramie. Truck has been deleted and "tuned". This is my first newer gen cummins so Im unsure what all that stuff means (always owned 2nd gens). Anyway, i was driving my truck home from a trip and left a stop sign when my transmission started to freak and jump between gears...

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...

    Been having this issue the past couple of months now. 68rfe will shift fine until it’s fully warm and then it won’t shift past 5th gear. I’ve installed a new transmission oil cooler, I’ve replaced the transmission line pressure sensor (external). Still haven’t found a fix. If I let the truck sit...

    Hello, I recently had my front drive shaft go out, didn't break but the centering knob in the u joint wore out and I pulled off the highway, got a tow home and replaced the drive shaft. Shortly after that, my transmission started to hang up in 2nd gear, not shifting past unless I accelerated...

    Hello guys I have a 2017 ram 2500 CTD with 106026 on the clock and these codes popped up yesterday. The truck was deleted at 96k miles. Would these codes be directly related to the delete? DPF and EGR and DEF deletes w EFI LIVE /80 hp tune.

    My 2009 Dodge Ram 2500, tuned and deleted. It goes into limp mode randomly. Replaced valve body and tcm and it’s still happening. It’s throwing a p0765 which is for shift solenoid D. Every time it does it I delete the codes and take the power wire off the tipm to cut off power to everything then...

    Hello, I've tried the search function but can't find the specific info. I've recently installed a protect68 kit, following every single step in the manual torquing the bolts down and quadruple checking them just trying to be really careful with everything I do in there. Now the transmission was...

    Hey friends, Plain and simple... But maybe not. I'm currently driving across provinces, just outside of the Rockies. I decided to head up a mountain today with my 30fter (huge mistake, didn't research the route) to go on a hike and long story short I brought my trans up to a whopping 260f...
