More 48re questions, hoping for tranny guy response
 

So I wanted a couple more tools in my toolbox, or ammunition for fighting the dealer about my 48re tranny woes. Wanted to explain what I am noticing and see if any of it is normal int he sense that a completely stock truck does it. Also at what level SHOULD dodge fix it?

truck: 2004.5 ram 2500 2wd automatic with approx 37k mi on it. Purchased with 32k mi. Had kickdown band and solenoid pack replaced on tranny about 300mi into my ownership which did nothing to remedy these exact same symptoms.

Whats happening:
Seems like there are two modes of operation currently with my transmission....

Normal - Generally shifts well, feels like torque converter is letting go ok, and 3rd to overdrive seems to shuttle shift (feels like it shifts to overdrive to 3rd to overdrive). The shifts are a bit firm, but what I'd expect and generally pretty acceptable.

Broke - Always when warm, and after driving a while... turning off, and starting back up. Intermittently. Truck will shift very harshly from park to reverse and reverse to drive... hangs on to 1st gear way too long and when it does shift... its harsh... usually a decent BANG to it. Likewise coming to a stop it downshifts and they are pretty harsh as well.

Intermittently the truck wont shift into drive from park or reverse... and I have to actually go back to neutral and then back to drive. (wiggling the shifter doesnt kick it into drive).

I know this tranny is notorious for solenoid and line pressure problems and/or this may be completely normal operation of the transmission.

I just have a few questions about what may be wrong, and/or how to get the dealer to actually do things with it.

1) Do any of these things occur with a brand new completely stock 48re? I need ammo for taking the truck to the dealer... and having them actually do something about it. They took my truck and had an employee drive it for a week (which he was BOUND to experience it a number of times) and yet they say nothing wrong.

2) If not, and they wont fix it, are there some cheap things I can try? I'm at my whits end with this, and cant afford a full blown goerend tranny all in one swoop. I'd be willing to try another solenoid pack, or a shift kit, or a full new valvebody. I cant afford a new tc at the moment =(.

3) Can I install a valvebody without installing a torque converter at the same time?

I just want to be able to tow with confidence... and my dealer is basically skirting the issue. Every time I bring it in, they find something other than the transmission problem, and its 100$ deductible haha.

Appreciate any response what soever, from a dodge mechanic would be even better. Thanks all.

update, I called the original dealer which did the original transmission work and they said over the phone "...it sounds like it could be a valve body problem..." which is at least "...there is nothing wrong with it..."

Going to drop that off with this very detailed list of symptoms... as well as mention my problem with harder starts when warm.

If it's under warranty I would just push the dissatisfied customer role to the hilt. When I took our '07 in for the solenoid TSB they called and hour later and said to come pick it up, they couldn't find anything wrong after a test drive. I went back in with the TSB in hand and asked if I needed to speak to the service manager, or what. They pulled it back in and did the work.

[Edit] I see it may not be warrantied based on age, unless you have an extended warranty plan.

absolutely and absolutely my reason for even asking here... like is it unreasonable to think something is wrong with the transmission if its shifting like it is?

Is it reasonable to expect the truck to get fixed under warranty or should they only fix it if its catastrophic failrue where I cant drive it anymore?

I just dont know.

It is definitely not shifting right and no it is not unresonable.

Is it under warranty, or not? They went to a 3/36 warranty somewhere around the time yours was sold, so like I said, unless you have some kind of extended warranty you are probably SOL.

I have an extended warranty... and I've just been through this exact sort of thing with my bmw... I know how dealers like to skirt issues... took me about 15 visits to the dealer to get my bmw problems fixed.

Ok, so after a couple more visits and finally taking to a different dealer, I managed to reproduce the problem with the tech in the car. He, along with chrysler engineers decided I need a new valvebody (as they replaced the kickdown band and solenoid pack already).

I am somehow skeptical that this is really going to do a ton... we'll find out ina bit as they are supposedly on backorder with no estimated date.

classic quote frm dealer when i told them I was to be towing a hotrod in 2mo or so...

"...I wouldn't count on having it ready by 2mo..."

I'd like to know why they can't get a valvebody in a timely manner. Those things should be pretty common pieces.

any chrysler techs care to comment

Two things you can try is the Borg Warner upgraded governor solenoid and the transmission output speed sensor. They can both contribute to the described intermittent problems. A place to start anyway.

Yes, you can replace the VB with a built one that has a shift kit and higher pressures without replacing the TC. You can save yourself some $$ if you can find a local shop to do a shift kit. If you do a shift kit or VB there some other small parts that need upgraded to make sure it will not break.

Unfortunately, if you want it fixed right its going to be on your dime unless you source the parts and the dealer will install them for you at little cost. Most of us just do what is needed and forget the warranty for little things. Do the trans right and if its a solid unit it will outlast the warranty.

It sounds like the Dodge dealers stick together. I've had our 2006 back 3 times and Dodge couldn't find the shift problems. I'm glad I didn't let them drive it for a week. I've found out more about the 48RE transmission problems today, than I would have from the dealer. Now that it is out of warrantee, they will find the problem and charge accordingly.
Once it warms up, it starts the shuttle shift or erratic shifting. It's good that is has descent metal in it because part of the time when it does it's (thing) It should break the transfer case or driveline or something.
From the best I can tell, the governor pressure solenoid and transducer/sensor seem to be a common problem with these transmissions. This truck has 37,000 and the transmission pan and filter/screen was amazingly clean. Maybe we should suggest to the Dodge dealers they join a group like this.

any comments??

A Cummins Dodge is a great truck, it's a shame the dealers or who-ever won't fix the common problems. I appreciate all the info that is just on this sight....
Thankyou

I was talking to my dad about this... I guess he knows some old school chrysler mechanic... The guy says 48re is a rock solid tranny ... But you have to be religious about service on them. seems obvious to me that there are problems with stock solenoids.... I don't know... I'm really quite happy with my ctd in general at this point.. Just wish it'd shift a bit more predictably.

I believe that to be true. I also believe the culprit in the service issue is the fundamental nature of running an inefficient filter in a system that often gets ignored just because they do tend to be relatively trouble free under normal conditions. Clutch debris is always shedding, so at some point they start the internal self-destruction process from either loading the filter or oil itself to the point of failure. I added a Maghytec DD pan and an external bypass filter to mitigate this issue, hopefully adding service interval headroom, and extending the overall life of the gearbox.

STEALERSHIPS not Dealerships monkeyball you any which way then can!!!!:moon:

The 48RE has to be strong, but why like so many other things in todays life, did they have to computerize a transmission that probably would outlive half of us? The 727 and turbo 400 even the 350's lasted and shifted good with little maintenance. got carried away. It's scary to read the service manual about the workings of these transmissions.
unclean electricity from the alternator, reflash the computer, sensors, pressure transducers. It was designed to be a gear box.
