Car Forum / Dodge / Dodge Trucks / December 20052003 Ram diesel auto slamming into 2nd gear at 80mph on freeway!
My 2003 Ram diesel automatic has had this problem before and under warranty they "fixed" it (don't know what they did/didn't document it.) Now we're way out of warranty and it has started again. I'll be driving down the freeway, whether at 65 or 85mph, and I'll feel the truck suck back power for a split second then the whole thing lunches, jarringly slows down with crazy revs going on, it red lines the tach and I'm in 2nd gear! Along with this problem is the fact that I feel the truck has lost a bit of oomph. I feel it sucking back when I step on the accelerator; it feels like a pressure build up and you can hear the engine revving higher, but it doesn't go a lot faster like it used to. And it feels like it's going to slam into 2nd gear. Have also lost a bit of towing power too. WTF? I initially thought it was the transmission, but it really isn't. Tranny works fine. Could it be the PCM or the MAP? Would any of this be covered under the "Powertrain" portion of the warranty (which is more extensive/longer than the standard portion)? Anyone have this problem? Or is it just my doomed truck? (I've had EXTENSIVE problems of EVERY sort with my truck.) ~Bev > I initially thought it was the transmission, but it really isn't. > Tranny works fine.

Regardless of the problem (mechanical in the transmission, or electrical with the PCM or related sensors), it should all be covered under the 7/70 powertrain warranty. Something's causing the front band to apply, and that's putting you into 2nd gear (actually, most likely a hybrid of a gear somewhere between 2nd and 3rd in ratio, because the OD is probably still engaged). It could be something mechanical, as in a leak in the valve body that's allowing pressure to flow to the front servo - or it could be electrical, as in a bad governor pressure solenoid that's not keeping the governor pressure up where it needs to be. Thank you so much for your time. I remember them mentioning something the first time (when they "fixed" it) mentioning the word 'pressure' so I am going to hand the dealer mechanics a list of things to look over. May sound silly, but it took 5 (five) trips to the dealer mechanic in 2 months before they "fixed" it. They kept just sending me home with a note "could not duplicate problem". So both of these suggestions are going on the list. And I KNOW they are going to try and charge me and claim it's out of warranty. So that's why I wanted to know if you guys felt it was to still be covered under my 7/70. Seeing that we feel it should I can go in there with both guns blazing when they hand me a big fat bill. Thanks again! ~Bev > Thank you so much for your time.

Just because some well meaning folks in this newsgroup "feel" that your problem is covered under the 7/70 powertrain warranty doesn't make it necessarily so. After all, no one here can be certain of what the problem truly is. The final arbiter of whether warranty coverage applies to your repair is DaimlerChrysler, not the dealer. You should advise the dealer of the problem with the vehicle and ask that you be called with a diagnosis and estimate of repairs before any work is commenced. Be advised, that if the repair is covered under the warranty, then the diagnostic charges will be covered also less your applicable deductible. If on the other hand the repairs are not covered under the D/C warranty, then you are obligated to pay the dealers reasonable diagnostic charges to ascertain the problem. You should be advised by the dealer what the diagnostic charges will be before the work is started. Make sure you ask what the charges might be if the dealer fails to do this. If after the diagnosis, the dealer determines that the repair is not covered under the warranty, ask the dealer to do a VIP inquiry for warranty coverage. This report from D/C advises the dealer if the repair is covered or not. If it is not covered as outlined in the report, there is nothing the dealer can do, he does not make the warranty decisions, only D/C can do that. So there is no need to go in "with guns blazing", that will get you nowhere. As an educated consumer, you should be aware that anytime you ask someone to perform a service for you, there will be charges that have to be paid by someone. Always determine in advance, who that someone may be. Hope this helps! Chryco Service Manager > certain of what the problem truly is.

Right... and the dealerships always follow the rules, and never try and charge for something that should be covered under warranty... >> certain of what the problem truly is.

That's why I recommended she ask the dealer to run the VIP, that way there is no monkey biz and she will know the straight skinny. Mike Perhaps is the truck named : Christine? heh heh Thanks for the help, all! Yup, the actual gear lever is physically down into 2nd. Don't know how it gets there, but when I'm freaking out on the freeway and I reach down to change it back to "D" I am able to do so and all is well again (till it decides to do it again). So it may be mechanical, but there has also been a noticeable loss of power/acceleration in the truck too. So I'm taking it in tomorrow morning and see what that gets me. The key code thing is a bit odd, too. Yet something else for them to look into. ~Bev Yup, if the lever is doing that, its a problem in the column. The power may be down because the PCM sees this recurring event and doesn't know where its coming from.

" Oh, yes there is. It's amazing how much better the service got when I stopped being the nice, understanding girl and turned into a flaming bitch. I only turned into a flaming bitch when the sevice advisor became so patronizing that it went beyond rude and became insulting. They would NEVER have spoken to a man that way. After I opened my can of whoop a.s, they pulled out all the stops. I finally got to deal with the service manager who took me seriously, actually contacted D/C with my truck concerns, got answers from D/C, actually fixed said problem AND detailled my truck & gave me a free rental. So being an educated, reasonable person doesn't work at this place. Once they became customer service oriented & reasonable with me, then I was able to put away the flaming bitch. But I'll definintely make note to have them contact D/C regarding the VIP inquiry for warranty coverage and get the prices up front for any diagnostic work. ~Bev > "So there is no need to go in "with guns blazing", that will get you > nowhere.

If its really the trans, it'll either show as governor codes, or no codes, indicating a hydraulic problem.

If it's shifting from 4th to 3rd (ie. same result as if you hit the O/D off button, or floored the accelerator), this is a likely source of the problem. But if it's really dumping into 2nd gear at those speeds, it's not because of a flakey APPS. At 85MPH, with a 3.73 axle ratio, dropping into 3rd would put your engine RPMs at about 3400. Dropping into 2nd gear would have them at almost 5000RPM. When this happens at 85MPH, do the RPMs go over 4,000? No, it is truly dumping into 2nd gear. I know this because I have to reach down to the gear lever and bring it back into D from 2nd gear. As for how many RPMs it hits in 2nd gear at 85mph, I can't tell you as I am so freaked out when it happens that my first line of business is to keep the truck from getting suddenly rear ended from behind (because of the sudden lurching & deceleration), and then it's to pop it back into D. I never thought to look at the RPMs, but they are through the roof by the sound of the poor truck. ~Bev > No, it is truly dumping into 2nd gear. I know this because I have to > reach down to the gear lever and bring it back into D from 2nd gear. Okay..... hold everything.... The GEARSHIFT is actually dropping into 2nd??? That's a whole different problem - and strictly mechanical in nature. The APPS is the diesel equivalent to the throttle position sensor. You don't mention if you got any codes. On the 03, turning the key on and off three times, then back on, will cause all diagnostic codes to be displayed on the odometer. If you are in possession of these, its more ammunition when you talk to the service manager. SignatureMax "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

I need as much help as possible there. They really do talk to me like I'm a total moron, or patronize me and all but pat me on the head and send me on my way with a lollipop. And I don't know how they can't duplicate the problem as it happens to me everyday with others having been in the truck with me to witness it. ~Bev Hey! I did the code thing and got: P0633 P0219 Does that mean anything to anyone?? ~Bev See Below > Hey! > [quoted text clipped - 6 lines] > > ~Bev FMB >> P0219 Engine Overspeed Like she really needed the $&@^!^$ computer to tell her that! :^) 0219 means engine overspeed, so it looks like your trans has in fact downshifted. 0633 indicates SKIM Key Not Programmed in PCM I'm not familiar with the second code, Tom Lawrence has an 03, if he doesn't chime in shortly, ping him or email him.

My guess would be her truck wasn't equipped with the Sentry Key system, and that code is just always there. That, or the PCM lost it's secret key, and therefore the Sentry Key system isn't working (ie. any old key will start the truck). I might mention it to the dealer when it's in, but it's not part of this particular problem. |
