hey boys, fairly new to this forum. First Thread anyways ...

Here is my issue, when I took my truck out on saturday, i pulled out of the driveway and the truck did not want to move forward. I cycled the automatic tranny from Park to Drive and then it moved but felt like it was slipping... it happened once or twice before but it went away. Anyways, this time the truck shift from 1st to 2nd and then when it reached about 2200 rpm and went to shift to 3rd but it would not engage and would slip back to 1st. It would then be stuck in that gear and would stall the engine if I hit the brakes. An engine check light eventually came on after about 10 mins.

I tried to screw around with the overdrive, the - / + shift, the traction control and 4wd but no results. So I brough it in to the dealer and they told me the transmission would have to be entirely overhauled .

I'm just curious if anyone else has had this issues on 4th gen trucks. Mine has about 7000 km on it, and is being babied...

Any one else in the same boat ?

I'll post the results of the overhaul once they find out what the actual issue was for you guys to be aware.

Wow I'm sorry to hear that. Mine seams ok so far. Only 6000 miles

Ive had the same problem with my truck to, itd start shaking in reverse so I took it in and the mechanic told me it was the clutch for 1st and the reverse gear. So they replaced it and Im having the same problem, faulty parts?

 

[ram7833]

it's either some el chipo parts from japan or there is a definite flaw in the design. From what i've been reading it seems like a faulty selenoid, but you wouldn't have to take the tranny apart for that fix. So who knows ... back in the days when i drove my ford escort it had the same issue, but back then it was easy... leak or no leak now about 20 years later there is so many "made in taiwan" electronix that is screws things up royally. Im glad it happened now and not while im driving 20 hrs in the country to go hunting ...

had the same problem, had the front pump and torque convertor replaced problem resolved this problem only occured in the morning

Ram7833, when your truck started stalling (when you would brake to a stop), would it then be OK when you restarted it? Or would it immediately stall again as soon as you shifted it into gear (Drive or Reverse)?

When you say it "did not want to move forward", do you mean it would only move when you revved the engine way up? You said you pulled out of the driveway first, was that in Reverse? So Reverse was OK but Drive was no go?

Did the oil smell burned? Did the dealer tell you any fault codes it had?

TransEngineer: to answer your questions, the engine would stall when I would hit the brakes, but it would be fine if I restarted it and the scenario would repeat again when I would put in in drive.

What I meant was that it seemed like the it was slipping and I had to rev it real high for the struck to start moving, but in reverse it ran like a regular truck. I wouldn't know anything about the oil because I took it in almost right away. For the trouble code, they did not say much other than they did not know what it was and decided to take apart the tranny.

 

[ram7833]

So, I called up the dealer to days and they said they had to order a new clutch pack. They found out that somehow, when the truck was build, the original transmission filter was sit properly therefore "airaiting" the oil. The oil eventually bubbled up which apparently burnout out the clutch...

Does that make any sense to you gear heads ?

I don't think the aeration was your problem (it was a symptom). I think your problem was a misinstalled (or loose) filter that fell out of position and then gave you no (or very little) line pressure.

Hard to say without actually seeing the parts. Did they say whether the filter was damaged (like cracked or split open), or was it just mispositioned?

They seemed to say mispositioned from the factory.

I have no idea how the tranny works in the truck, but in my mind it just seems like if it was mispositionned then it just wouldn't filter properly no ? kinda like an air filter ?

This sounds a little similar to another thread that an owner had where the spin-on filter in the trans loosened or backed out on a new Ram. Hope this isn't a frequent quality control issue.

 

[ram7833]

well i'm glad to hear that this is something that is actually plausible and that the dealer isn't trying to pull a fast one on me... that being said, hopefully it's not something that is that common with the new 4th gen... it would be to bad that such a nice truck with be put together with sub par standards from the get go ...

No, the main sump filter has a snout that sticks up into a bore in the pump housing. If the filter is mispositioned, so that the snout comes disengaged from the pump bore, then the pump sucks AIR (from around the filter snout) rather than sucking oil (up through the snout). That gives you no drive (or very little drive).

We typically do not see issues with the spin-on (cooler return) filter (which is also inside the trans) coming loose or falling off (although I have seen a few reports). Problems with the main sump filter are much more common, although usually they result from a botched fluid and filter change (not from misinstallation at the factory).

Just had our first problem like this over here in Britain - vehicle is a 2012 Hemi Quad Cab and customer has just phoned up with what sounds like exactly the same symptoms. Vehicle will not change past 4th - rolls back even when in Drive. +/- makes it change but not as it should do

well boys, this issue just happened again over the holidays... only this time I was out about 1000 km at our hunting cabin and driving an unplowed road. everything was fine when out of a sudden the engine reved right up and the truck had no more drive. The tranny indicated 4th, but it did not move from there. Neutral on the transfer case would not come on either, gears, reverse nothing. It was -37C ... Had to get my brother to come tow me out so that to road side could come pick it up. its been in the shop for 2 weeks now and they cant figure it out. 2 Trannies in 56k ? anything that i can do here in Canada to get the truck replaced or something !?!?

 

[wilhavens]

I have 74k on my 2011 and haven't had an issue with the trans... but I did have two teeth break on the rear pinon gear and i made a similar noise.

 

[huntergreen]

wonder if the extreme temps have anything to do with this.

Did they tell you what fault (or faults) you had? Have they checked the filters?

 

[my hemi]

transmission

hi i have the same trouble like you guys truck stall at a stop and they check the transmission filter and it was split obout 6 inch i will try it in the morning if its ok but before that they change the fuel pump change throttle body valve and throttle body Inside the transmission and the filter was good drove a couple days and still the same what a big lemon

Yes, the split sump filter is an issue we have seen on some trucks in cold weather. The new Mopar filters now have a pressure relief valve added (rubber "mushroom" pop-off on top of the filter) to prevent the split filter problem.
