1st off how did you get the code with no code reader?
Did they quickly move the key on and off 3 times? and read the code in the dash?
the 0700 code is usually involves 2 sensors (governors) in the transmission under the pan. You can do the job but you best know what your doing.
if you remove the wrong bolts it will be a night mare.

My advise, take it to a tranny shop it should not cost all that much at all.

On the Dodge trucks that code indicates there are more codes inside the TCM. Most aftermarket scan tools don't have the capability to ready TCM codes (for some reason). Have the owner take it to a tranny shop.
  • With the trans not shifting out of first, does this also happen when you put it into manual 2 and manual 3?
  • Does it feel like there is any slippage while in 1st?
  • Was the tranny fluid flushed or just drained and filled?
  • How many miles on the truck?
I'd lean towards an issue with the valve body but depending on the mileage and condition of the old oil, a rebuild may be needed.

1- Park, Reverse, neutral, and 1st gear, even with manual shift.
2- Driver say's it hold 1st gear well.
3- Just Drained and refilled... Fluid was not burnt or discolored, No filter change needed. No hard material, Not much soft lining, Fairly clean in the pan..
4- 145,000 miles.....

I'm not sure of the details. Some of the 518 versions one of the solenoid is mounted with three small bolts -The heads sometimes break off loosing fluid pressure ?? worth checking before a rebuild

Bob, It is not stuck in 1st gear it is in 2nd gear and it is in limp in mode...You need a scan tool to properly diagnose the problem..But if you have just serviced it you might have fixed the problem. Un hook the battery for an hour or overnight is better. Then give it a test drive to relearn everything.. It would be better if you have the tool to clear the codes...Bill

We have had a lot of comp probs lately. Meaning we replace a lot of them then have to take it to the dealer to get programmed. But you better get it scanned by a good shop before you do anything. Wiring probs can cause codes too,which is the leading prob with late model Mopars.

UpDate: Road Trip did not go so well.... The truck will only move forward in 1st gear, That's it. The truck dose have revers. But as soon as you drop it into drive, You have to throttle it just slightly for it too jump into first gear.
I could not scan the truck.... It appears that someone forgot to tell me of some other electrical issues. So I advised him to being the truck down to where I am at so I could look into the problem further. That's a 4.5 hour tow.
Any How here are my thoughts..... It is ether...
1.the electrical issue mess with this thing...
2.The Trans coil pack....
3. It broke the snap ring or pin on the drum...

I'll up date Y'all if it makes it down here for me to fix..... opcorn:

Well the truck has made it down here from up north....
We have got the Electrical nightmare fixed.....
(You have to remember. This was the 1st year for the 5.7 Hemi in these truck. All this stuff was different than all the other models)

As for the trans problem: So far here is where I'm at...
PO700 Trans Controller fault
PO731 Gear Ratio Error in First
PO1790 Fault Immediately after shift
PO876 Under Drive pressure switch Sensor Curcuit
PO841 Low Reverse Pressure switch Sensor Curcuit

Just a reminder the driving condition for this was:
truck moves in reverse...
Truck goes into 1st gear only... However you have to give it just a little throttle to make it catch. And it wont come out of 1st gear no matter what you Do.....

Going to start checking all the code by there diagnostic procedures and then if that dose not show any good results, a full new coil package and wiring harness... Well see what happens from there...???????

Just food for thought.....
Most of the time, these vehicles will go into a limp mode which puts them in a second-third gear mode too get home in.
This one is positively stuck in low gear when in forward range.

Come on Gentlemen....this is the way you fix them....RITE?????

So the solenoid bolts were broken ? $2500 sounds like a lot for a buddy price..
I went through the airport once with my Dodge van with a car in tow on a dolly..

UpDate....2003 Dodge Ram 2500 4X4 5.7 Hemi A.t.

Well this turned into a nightmare.. Going to give you the short story.....
Trans was taken apart and what was found..... One of the spool valves got loose from the valve body? (Dont ask me how that could happen Cause I sure the Fk dont know) Thats what toasted this trans...
So this trans got a complete O.H
Clutch's, seals, plates, Valve body, solenoids, sensors, coil packs, wiring harness, convertor, in-line filter.
Now with the Combo of the Reman 5.7 and a overhauled 45RFE trans...
And after spending 8,000 buck....
This truck is ready for the road again.....
Man the things we do for our Kids......
