  1. 2013-2018 Powertrain
    I realize there are multiple threads on here for this code, I’ve been reading through them for past couple of days and I’m sure the general consensus is that the only fix is a complete rebuild or a new/reman replacement but what I’m looking for is what parts are most likely crapping out so I can...
  2. 94-98 Powertrain
    Lately I have been having an issue with my trans not wanting to shift out of 1st gear until I am going about 26-30MPH. I read some posts about it being a governor pressure solenoid issue or the transducer. Would the pressures reading good on a shop computer rule out the issue? I am looking at...

    Just recently put a new input shaft in my 47re and after reinstalling it creeps forward after hitting about 130 degrees. All of the information I have when the trans is running is coming off the smart tuner screen so not sure how accurate that is anyway. Truck had a long shift when I first drove...

    Hey y’all. I have a 2003 dodge 2500 Cummins. I want to get a tuner that will show higher performance ability but also safe on the transmission. What’s your recommendations?
  5. 03-07 Powertrain
    Discussion Starter · #2 · a moment ago Hey everyone. Was starting this thread because my 2006 cummins has a tranny problem and I would like some reassurance that the transmission is not totally screwed. The truck starts off in 3rd gear from a stop. When I manually put it in 1st, and give it...

    ***Advice and input needed: Well, I think I may have arrived and the dreaded time of my tranny needing replaced but would like confirmation, ideas, and suggestions from the group. I'm the 2nd owner with 231,000 miles on the truck. Purchased at 213,000. Unknown if truck has original tranny...

    curious to see what’s out there…
  8. 89-93 Powertrain
    So I need a little help identifying a part/diagnosis. My 1991 d350 cummins is leaking coolant close to the block on passenger side. It’s close to the transmission line and I’m pretty sure it’s making it over heat and go in limp mode. Could anyone help me figure out what part/gasket or even what...
  9. 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...
  10. 2010-2012 Non-Powertrain
    I am looking to upgrade my current work truck to one between 2013 and 2018 3500. I prefer a G56 but have heard the AISIN is not terrible. What would be the general consensus?
  11. 98.5-02 Powertrain
    Hello, I have a ‘99. The transmission in this truck has been great for the 30k+ I have owned it. I have the noise isolator on it, I believe it has a Goerend converter, and something done to the tranny (have been in a lot of stock 47re trucks and none shift as good) however, it’s been about 95...
  12. 98.5-02 Powertrain
    I have a 6 speed 02 ram 3500 that the clutch recently went out on, so I had a new 1 put in. The person doing it for me of course dropped the light bulb in his head and got air in the system. Even after bleeding it, putting new clutch master cylinder in and bleeding, him dropping tranny again...

    The tranny (nv4500) chatters in 4th gear only and only when in lower rpms. It has a south bend dual disk clutch.Is this normal?

    i have a 1990 non-ic 12 valve auto with the torqueflite 727 tranny (3 speed no OD). I was wanting to throw a ratchet shifter on it for a bit but have no clue on how I should set it up or what all parts I should use. what's your opinion? is it worth it? have you or anyone you know done this? what...

    Hey guys I’ve got a 2007 with edge juice with attitude cold air intake and ccv delete fleece cheetah and I did the ats valve body upgrade with the separator plate and accumulator plate and now I have a harsh down shift and it makes like a weird grinding noise some say it needs a relearn I have...
  16. 07.5 - 09 6.7L Powertrain
    Hi, just joined. Sorry if you have had a question like this before. So I had a small leak from the transmission for over a year, from the bolt on the passenger side that bolts the extension/overdrive to the transmission. The other day the car was standing after being used and there was a big...
  17. 2010-2012 Powertrain
    Recently deleted using ez Lynk and CTT. First thing: From what I’ve read CTT has very limited if any shift flare on their TCM tune but my likes to flare and I don’t like it... opinions? Second thing: The CTT TCM tune should have bumped my line pressure up to 225ish and now when I monitor both...
