Transmission 42le wount shift in to drive cod po731 and po736

With that many codes and those specific codes I would suggest finding a reputable transmission shop. I suspect either a wiring issue or a bad trtransmission control module. A good shop should be able to determine which in just a couple hours or so.

Hope, PO731 means Gear 1 incorrect ratio. a few things in/on tranny could throw this code something as simple as dirty trans filter,shift solenoid, trans control module to more serious internal damage. Check the attached links,instruction and guides, Good luck

Code 731 is for a problem with the gear ratio for first gear.
Code 700 is a general fault code that means you have a problem with the transmission control module or the transmission.
The 731 code can cause the 700 code, and the problem could be a speed sensor inside the transmission. The computer does not like the signal being sent from the transmission to the computer.

Your transmission is gone

Here is the definition for the code.

P0736 MITSUBISHI Description This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes
Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

If you are looking for the "TCM" it is pretty fair to assume that you have not yet scanned your computer network for fault codes. How do you know the problem is not being caused by something simple like a speed sensor? Just asking!

There is no "TCM" on a 2002 Dodge Intrepid. The transmission is controlled by the same computer module that controls the engine. It is called a "Powertrain Control Module" or "PCM".

CAPACITIES
Automatic transmission, 42LE Initial Fill..........4.6 quarts [1]

automatic transmission, Total Fill
4 speed 42LE..........9.3 quarts
Differential, Front..........1.5 pints [2]

1. With ENG at operating temperature, shift through all gears. Check fluid level in PARK and add fluid as needed.

2. 42LE transaxles built after 7-26-99 fill to 3/8" (9mm) below fill hole.

Hope This Helps.

********Make sure that you use the recommended type flluid ATF+4, as there are several types available. Using the wrong type of fluid will damage your transmission********

Try cleaning the throttle body. Does it do it more when it is warm outside?

HI....
I read your problem.
Here is some information about you problem.
2000 Chrysler cocorde. has a 42LE transmission.

The code P0700, Will set for an internal Trans. controler fault detected. "" For any fault detected on a trans. this is the first code to set. After come the other ones.
If it come alone, you will need to make some test to determinate
If the TCM ( Transmission controler module) is fault.

P0731- Will set if ratio of input RPM to output RPM does not
match current gear ratio.
one of the commom problem of this code is a Trans. slipping condition. or other trans. codes related.

If you can go to a Trans. specialist for a proper diagnostic and possibles solutions.

THank you I hope this information work for you.
