  1. 3rd Gen. Powertrain
    I have a whining noise that happens when the torque converter locks up usually exactly at 80kmh(50mph) and it will go away when I speed up around 90kmh and then comes back the loudest when I decelerate back to 80 until the torque converter unlocks. Goes away if you put it in neutral also. This...
  2. 2013-2018 General Discussion
    Hello, I’ve got a 2015 Ram 2500 Laramie 4x4 tuned and EPA violated with a 68rfe transmission. A month or so ago I noticed a vibration between 45 - 60 mph. I have to be running in 6th gear around 1100 rpm’s and start up an incline to make it happen. The truck will start shuddering slightly and...
  3. 3rd Gen. Powertrain
    2005 2500 5.9, 48re transmission, 273000 miles Looking for some input in diagnosing my truck here's what's going on. Replaced injectors 13,000 miles ago. Just had them gone through about 1000 miles ago. Truck does not smoke, have preformed kill test on injectors, that all checked out good. And...
  4. 98.5-02 Powertrain
    Hello everyone, I’ve been chasing an ongoing issue with my 2001 Dodge Ram 2500 5.9 24v Cummins. I’ve tried just about everything I can think of. Was curious to know if my transmission sounds like it’s shifting properly. I’ve adjusted APPS Voltage, Cleaned connections on negative posts. New...
  5. 98.5-02 Powertrain
    I had the transmission in my 02 2500 rebuilt at a shop near where I broke down and didn't really have the opportunity to research or find a tranny builder. The guy who did it seemed knowledgeable but also seemed like a salesman. The truck drives great and tows great after the rebuild but I am...
  6. 07.5 - 09 3rd Gen 6.7L Powertrain
    Little background of the truck, 08 6.7 cclb 90k miles with stock fuel and air (deleted and tunes/trans tuning) and 425s. So bought the truck about 6 months ago with 80k noticed in reverse it had a very low idle but never thought anything of it, then driving home from work one day I was in a rush...
  7. 2010-2012 Powertrain
    Just recently joined the Cummins family by buying a 2013 2500. It’s been downshifting pretty weird on one of the CTT tunes I’d been running and seen people posting their CVI numbers along with the torque converter slip rpms from ez lynk. Just installed another tune and going through the drive...
  8. 3rd Gen. Powertrain
    ‘06 with 48RE towing heavy float or RV trailer up low grade hills in Tow/Haul mode results in an early 4-3 downshift. When starting up a grade, adding power, the transmission downshifts before the turbo spools up, seems to be around half throttle. Typically I’m driving around 55 mph. I would...
  9. 3rd Gen. Powertrain
    I have a 04.5 cummins and can't get the TC to lock up. I have replaced: OD/lockup solenoid torque converter (new triple disc) changed fluid, filter wired up dummy switch The only code that pops up is intermittent ECM/PCM signal. I've checked my grounds and replaced batteries / terminals and...
  10. 98.5-02 Powertrain
    So yesterday I installed the power driven diesel trans cooler lines kit, dumped the pan, changed the transmission filter, and upgraded the air cooler for the 47re. I then added 10 quarts to the transmission, it has a mag hytec deep pan. Then I started the truck to get things circulating and I...
  11. 07.5 - 09 3rd Gen 6.7L Powertrain
    Got a truck in last night tranny was rebuilt about 2 year’s ago it’s tuned by Idaho rob and deleted. The costumer said that there was a weird 5-6 shift and it would bump it back down to 5th when you let off. If you keep on it light it will stay. So I took it for a drive and it was doing that but...
  12. 89-93 Powertrain
    Stopped to get fuel on Christmas Day. Truck seemed to be running weird “lack of power” when driving down the freeway. Went to leave gas station and truck fired up then died. Popped the hood and it was smoking from positive terminal when cranking and would not start. Tightened up all connections...
  13. 3rd Gen. Powertrain
    New member here. Finally getting around to fixing up my 3rd gen I bought a while back. It will eventually get a low COG build on 37s+ and gears. I appreciate any advice on - -DFC long blocks (expensive but they have a lot of upgrades that I can't get built/machined locally). Or is $6400 plus...
  14. 07.5 - 09 3rd Gen 6.7L Powertrain
    The other day, I started my truck, put it into drive and it died. It is a 2008 2500 with the 6.7 has 165000 miles on it. Did some quick searches and it sounds like it's possible the torque converter(tc). Most likely once it goes you will need a transmision rebuild because it will deposit...
