Looking for some help. I have a 2005 Dodge Sprinter 3500 series w/ a automatic transmission.
I have owned it since new & now it has 188,000 miles on in. Since new I have changed the trans fluid 3 times. Recently the trans has been acting up, making a whining noise & going into limp mode. Today I changed the fluid, filter & fluid in the tork converter. There was fluid in the adapter plug housing so I changed that also (this is the 3rd one that I have changed on this van since new). The pan & magnet had fine metal shavings in it. I drove the van & it was still in limp mode (2nd gear). I hooked up my DAD & cleared the codes, drove it, it shifted from first to 2nd & then stayed in limp mode. I checked the codes again & they were P220 &
P2221. Cleared the codes a couple of times & had the same results as before. I dropped the pan & There were more metal shaving on the magnet & some in the pan. Sounds like I may need a new trans. What do you guys think?
Thanks,

Hi
From the fault codes you gave
P2220 is 3 to 4 shift solenoid fault
P2221 is lock up clutch solenoid fault.

The whine emission is of concern since it tells me you may have one or more of the planetary gear needles or sprague clutches breaking up hence the noise and the metal swarf in the pan.
The shift solenoids do have filters on them if you drop the valve body and the circuit board. they may be choked with swarf.

Sometimes in these circumstances I do a clear, then drive the van tiptronocally before the TCM does it to see what the shift quality is like and see if it will throw a limp or code.

Dennis, I googled the word tiptronocally and the only reference was to your use. Your usage means:
thanks and congrats on introducing a new verb

Ohw
New tech word from little old me!
So means shifting the gears using the tiptronic control shifter before the TCM does it for you.

Could also be a bit like my Daimler Ferret scout car which has pre-select semi auto gearbox by Wilson, 'cept its has a clutch like pedal to effect the shift!
Cheers Dennis

You can see some of this in the dirt but the show stopper and the Centurion (this one a recovery unit) powered again by Rolls Royce Meteor engine.

The whistling howl of Rolls engine is very infectious. !

Update:
I removed the valve body & circuit board this morning. It looks like I bent one of the pins where the circuit board & the wiring plug meet. I tried to straighten out the pin but it broke. The pin is the one at the 6 oclock position (bottom). Guess I will need a circuit board. Does anyone know what this pin wire is? Is it the rpm sensor?
Also where is the best place to get a circuit board?
Thanks,

You can obviously get a board from the MB dealer at about $260.00
An alternative is from Trans star.

Serving the auto trans re-builders they are nationwide.

Anyone near you?
They even sell hard paper manuals on transmissions including the NAG1.

Thanks Dennis! I can get one trom Small Fleet Parts for $148.00 & it will ship from a warehouse near me (have it in one business day).
Since I have the unit apart, should AI check the soleniod valve w/ a ohm meter, if so what should the readings be?
Thaks Again!!

Off the top of my head but between 2.1 to 5 ohm.:thinking:
