2006 Ram 2500 auto tranny slipping

Do I need a new transmission?

2006 Dodge 2500, 5.9 w/ a 4 speed auto. Truck has 108k on the ticker, and is bone stock. Truck has not been abused. It pulls a 5th wheel camper, about 11,000lbs, twice a month or so.

Truck has always felt odd in 2nd gear, like it has never felt like it pulled hard at all, whether empty, or towing. Pulls fine in first, pulls real hard in 3rd, but 2nd has always been weak.

If I let off the gas, it'll shift, but if i stay in the gas, it'll just rev up. Fluid level is fine, fluid does not smell burnt.

Do I need a new transmission? I have read about tightening the bands? Is this something the stealership can do?

I'd check the TPS and such first.

I did some research over the day...

It seem that there is a shifter solenoid and pressure sensor that can be replaced with a borg warner unit. I think the issue with the transmission is that it's not "slipping" per say, it just doesnt know when to shift.

The transtar part numbers are as follows:

12432A BW Selenoid as well as 12415C Governor Pressure Sensor (Transducer)

---Going to place order later, it's worth throwing $100 at the transmission just to see if that does the trick. Will replace the sensor and solenoid and see. Then, adjust bands...if it's still slipping, i'll just light everything on fire.

you can adjust the front brake band on the left side of the trans, real easy.

Isn't that the 2nd gear band, the front band adjustment is inside the pan I believe.

AT 106k, if it hasn't been done, go get a basic service, have them check the band adjustment. You may need a new transducer and possibly a solenoid.

If you are lucky like me, you'll find a small chunk of metal in the bottom of the pan that looks like this:

http://www.pirate4x4.com/forum/showt...light=autozone

Which you can have replaced with the transmission still in the truck. The piece that came off allows you to snag 2nd gear. You might be going from 1st to 3rd. After 3rd and up the computer does the shifting, or so I'm told.

There is no 1st brake band, there is only a 2nd and reverse brake bands. 2nd is adjusted on the left side of the case and the rev band after you take the pan off on the reverse apply lever.

I did read up on the band....that seems real simple. I am going to go ahead and replace the solenoid and sensor. The symptoms the truck is having, are about spot on with what the 2 new parts fix.

I don't think that'll take more than an hour start to finish.

I think this is something that needs to be done and hopefully the 2nd band isn't toast already. I'll swap the solenoid and sensor, see how it drives, then if necessary, adjust the band.....or just adjust the band anyways. The truck is stock and hasn't and there is no reason for this transmission to be toast already.

There's a certain truth to earlier posts about your transmission being shit.

It's a Chrysler transmission and any time over 70-100k miles is BORROWED.

This coming from an owner of two dodge autos. I just dumped my 1/2 ton pickup for a ever so slightly newer chevy with a new 4L80E. The cost of the transmission rebuild was damn near the cost of that entire truck.

This, I know. The more I read though...the more i'm finding out a few simple mods can make the transmission last a lot longer. I'll turn some wrenches on it this weekend and post results.

you need a good built valve body and a decent converter with a billet cover. My trans consists of a HTS valve body, billet apply and accumulator apply pistons with double seals, billet 2nd apply lever, billet strut, billet anchor, alto red eagle solid sintered iron 2nd brake band, DTT custom full billet super single tq converter. I also made my own laminated flex plate. The rest of the trans is 100% stock as a rock, i didnt even touch the clutches or seals, its been holding 20-25psi boosted launches in 4wd and tows no problems.

My truck's stock trans was handling a Smarty SR programmer fine.......but I could get it to slip when loaded on the #9 tune with 37" tires

Here are my trans parts list:
Mag-Hytech Double Deep Trans Pan
BD FleX-Plate
Billet TCS Output Shaft
Billet IE Opie Input Shaft
Goerend Valve Body
Goerend Triple Disk Torque Converter 900/300
Diesel Site External Transmission Filter Kit
Sonnax Billet 4 Ring Accumulator
HD Band Anchor: "The Power Wedge"
Billet Rear Band Servo w/ Pin
Sonnax Dodge 16% Oversize Intermediate Super Servo, Servo Cover and Pin
Sonnax Front Servo Piston Cover
Billet 4.2 Apply Lever
Billet HD Strut

One year later, so far, so good.......no issues or problems. With the Goerend VB and Triple Disk TC, it locks up storng and hard in just about every gear. I just had the two trans filters replaced and the fluid flushed, and the old fluid looked really good.

I'm thinking a valve body and some sort of after market TC will be in the future of the truck.

Thanks for the info...and from you sig, i bet that truck is one hell of a fun DD

I've been reading a lot of good things about Goerend transmissions/upgrade parts.

My 04.5 is doing the same thing. Shuttle shifting from 1-2. I changed the fuild about a month ago then took it in to the dealer to have them adjust the 1-2 band since I couldn't get my fat butt under there and still be able to reach it. Cost me $43 to have them do it.

How much are the governor solenoid and sensor to change? I can do this myself but haven't been able to find the pressure sensor on Napa or Rock auto's website. Looks like the governor solenoid is about $90 or so.

I searched for the part #s listed but it turned up nothing on Napa's website.

EDIT: The info below is assuming you've got a 48RE auto....

Go to this website:

http://www.transtar1.com/

Click locations...there might be one local to you. If not, call them up and order part numbers 12432A BW Selenoid as well as 12415C Governor Pressure Sensor (Transducer).

I have not ordered yet, decided to try to mess with the band first, but it should run around $100 shipped for both parts. When you order 12432A, make sure you request a borg warner unit.

This link tells you how to replace both.

http://www.dodgeownerforums.com/smf/...p?topic=7526.0

it looks like a piece of cake...

Alot of people also suggest doing the GM Solenoid Conversion.......which is supposed to help with the 1-2 shuttle shifting

PATC sells a ton of good trans parts for the 48RE:

http://www.transmissioncenter.net/dodge.htm

Suncoast sells good parts also, along with Goerend, NADM, HTS, and Garmon Diesel (who I would highly suggestion)......

There are quite a few GM Solenoid kits on Ebay, just search "48RE Solenoid"

The Diesel Site external trans filter is a great kit, especially for the price:

I had the exact same problem with my 05 with 75,000 miles on her. First it was shuttle shifting and then I also noticed it seemed to be hanging in second on hard take offs. I replased the solenoid and switch the the borg units. That fixed the shuttle shift but not the second gear problem. I have just been driving it a little easier on take offs for now. When mine stalls you can drop it down into second manually and then it seems to lock up or something a then shift back to D and it goes on through the gears. It never stays in 3rd for more than a second or two, which makes me think I may have other problems.
