Dtc codes in my dodge 3500 5.9l p0720 and p0712. and tranny is slipping

SOURCE: need to know where is Low Output SPEED Sens RPM,

as far as i know there is only one speed sensor and it is located on top of the rear differential should have one bolt holding it in. i believe that code says the speed sensor has a low output.

SOURCE: i have 2005 dodge w code p0700 and p0712 what is

These codes are telling you that there is attention needed at your transmission.
p0700 code is the transmission controller, there are solenoids on your firewall that may need to be replaced.
p0712 code, is telling you that the voltage to the transmission temperature sender is too low.
I would discuss these codes with your reliable auto center, and get a quote for repair.
Please let me know what you find.

Hi,

It sounds like the transmission is in "limp in" mode.If a transmission will not shift out of 1st or 2nd gear, it's in limp mode. Drive the vehicle for about 10 or 15 min and turn it off. Turn the key on and off 4 times. (without starting the motor) This will reset the computer. When a trouble code is set in the computer, the transmission goes into "limp" where it will not shift. On that vehicle, a common cause of the problem is the transmission output speed sensor.
Have the computer scanned for codes (the transmission is scanned using the blue connector under the dash) that will tell you what the problem is. If it is the sensor, it is not an expensive repair.

The only way to get this up and running again is by having the dealer hook up a diagnostic scanner and read directly what is going on in the system, you may have a defective body control module, that would explain the starter problems, do yourself a favor have the dealer diagnose this to read the code.

Please accept the solution if it's helpful. Do get back to us for any further query.
