Dodge transmission issue
Hello,
Just bought an 2007.0 Cummins w/ 48re, still bone-stock, 50,000 miles noticing a couple of subtle transmission issues. (1) Under slow acceleration the transmission will hesitate between gears, a slight "back-and-forth" motion, or a lurching motion, is noticed. The lurching motion will continue until the accelerator is depressed further, when the transmission will finally shift into the next gear. Only noticeable in first couple of gears. (2) At highway speeds a similar lurching motion is noticed when traveling on slight downhill grades. The hesitation will continue until the truck is driven past the downhill grade. :humm: Checked transmission fluid, it needs just a little bit of fluid due to a leaking transmission seal, not very much probably less than a 0.5 quart. Haven't had time to purchase fluid lately with my work schedule, but it will get topped off ASAP. Any advice will be greatly appreciated! |
You can have your Bands Tightened that should help you

Whats the procedure on tightening the bands?
|
This seems to be becoming a common issue. Mine and a friend of mine both had this happen within the last 2 months.
I didn't notice it on my until I took it in for a tranny flush. He tightened a loose band and after that the problem showed up. Took it back and had him loosen it back up to see if it went away. It got worse. He then hooked up some diagnostic computer. Ended up deciding that the govenor solenoid was bad or going bad?. Replaced it $300 later and that took care of. Same fix for my friend. I had 68000 miles and I think he was around 74000. MInes an 05 and his was an 04, both with the 48RE tranny. |
govenor switch aqnd pressure switch both cost about 200 bucks plus a gasket, easy to change even for the mechanicaly challanged:U:

There are a few TSB's out for what you are describing. Perhaps they will assist you in diagnosing and fixing this problem. Hope this helps you out

had my 99 doing the same thing a couple months ago
took it to a tranny shop and they replaced Governor pressure solenoid fixed it right up $250 at the local tranny shop :U: |
NOT SURE ABOUT A 2007 But here the 2nd gen procedure
Dodge Diesel Transmission tips On of the most frequent questions I get on the Cummins powered Dodge trucks is transmission related. The Dodge automatic tranny is very robust and does what it was intended to do very well. But given the reputation for massive torque that the Cummins engine provides, many times the transmission is asked to do far more that the engineers at Dodge designed it to do. The best thing you can do to make the transmission last a LONG time is 1) Don't exceed what is recommended in towing, 2) Change, change, change that tranny fluid and filter, 3) keep the bands adjusted. What? you did not know that the Chrysler rear wheel drive units required periodic band adjustments? Both Ford and GM use a different system that does not require band adjustment. Just think about it like the comparison between hydraulic and sold cam lifters. One needs adjustment and one does not. But when a solid lifter engine is adjusted properly, just you watch out! I recommend a fluid change at 10k if you tow heavy. Fluid is cheap compared to rebuilding a tranny. I had a friend some time ago that rebuilt trannys for a living and asked him this. What is the one thing that would put you out of business? He said people changing their fluid often. Automatics get a bad rap, but most people I query on their change intervals brings up one glaring fact. THEY DON'T CHANGE THEIR FLUID OFTEN ENOUGH! So lets talk band adjustment. The front and rear bands need adjusting at every 24k miles with your fluid change. If heavy towing I would cut that in half. It is an easy procedure once you see how it is done. So follow along with the pics and let me show you how its done.... Keep in mind that these adjustments were done on a '98 24v truck. Depending on the year Band adjustments for each model year: These were borrowed from the TDR page.
These 2 pics show the lock nut and the adjusting torx T-40 screw. This is the front band adjustment on the drivers side of the transmission. Disengage the spring from the lever so your wrench will have some working room. Back off the nut about 5 turns and then torque the torx screw to 72 inch lbs. Then I backed off the torx screw (1 7/8 turns). You must do this! Failure to back off the torx will result in transmission damage! Then re torque the nut 30ft lbs. Don't forget to re attach the spring to the lever. Remove the tranny pan and filter to access the rear band adjustment. Back off the nut about 5 turns and torque the torx screw to 72 inch lbs. Then I backed off the torx screw (3 turns). You must do this! Failure to back off the torx will result in transmission damage! Then re torque the nut 25ft lbs. Install the new filter and pan, refill with ATF+4 and enjoy! |
Great info Dieselminded-will have to adjust them! :U:
---AutoMerged DoublePost--- Will have to have that replaced. From what everyone is saying, seems like a common issue on these! :6: |
Any updates? :pca1:
|
I've been pretty busy with work lately, so it might be a while.
|
K, just keep us updated if you could please!!! :c:
|
I will update as progression ensues!
|
Nice right up!! My truck is doing the same thing,do you guy's think this is covered by warranty,and also can this harm the truck????
|
I certainly would not recommend following that procedure on an 07 - take it to the dealer you should still be under warranty.
|
What's the good word?? :pca1:
|
Between my schedule and the dealer's schedule, I won't be able to get it in until Saturday the 3rd so kind its kind of in suspended animation..
|
K, I will keep the thread open for ya. :U:
|
Any updates? :pca1:
|
Still having schedule conflicts... will post as soon as updates arrive
|
Whats The Current Status Of this Situation?
|
Got it to the shop today, finally, where me and their Dodge certified mechanic went for a drive. After the test drive, he pretty much told me that there was something wrong with my transmission and I would have to reschedule for a later date when the transmission specialist will be there to diagnose it. Woo hoo, sounds great. :edit:, if it wasn't a warranty item, I would buy that governor pressure solenoid and probably fix the problem, from what my research looks like.
:argh: A dealership with even an "acceptable" service department is 100% invaluable... Anything better is golden! |
5 star only refers to the sales end. Nothing to do with the service end seems like.:booo:
|
he guys not try to hijack but i my 05 with 66000 on it was having the same problem took it to the dealer had them do flush,filter,band adjustment,and governor tsb for tha sum of $450 :ouch:now its worse than ever have an appointment on the 12th to see what they can do for it.:argh:
|
Finally got the truck into the shop--problem repaired--Dodge wouldnt warranty the problem since my truck did not have the extended warranty, the dealership stated that the 100,000 mile powertrain warranty applies to the engine only, unless the extended plan was purchased and documented.
Some sort of solenoid in the valve body, a transducer (?), and a range sensor. $635 before having it flushed and tuned up. Woo hoo!! Ya! Should have bought a dirty-max... :choochoo: |
Good deal!!! Will close the thread down and should the problem return, can reopen or start a new thread. :U:
