I have a 2002 Dodge Ingtrepid with a P0700 failure code. They said its the Transaxle control module. Can someone please tell how to fix this problem?

Is this P0605 and P0700? If so read on.
P0605 - Control Module Fault
Possible causes- ECM/PCM Harness power supply circuit is open or shorted
- ECM/PCM Harness ground supply circuit is open or shorted
- ECM/PCM may be faulty
P0700 CHRYSLER - Transaxle Control System (TCM) Malfunction
Possible causes- Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module
Tech notes Since the P0700 is just and informative code, check the TCM for more codes to resolve the problem

P1782 DODGE - 2/4-OD Pressure Switch Circuithttp://engine-codes.com/p1782_dodge.htmlForum CodePossible causes- Low transmission fluid level
- Dirty transmission fluid
- Faulty 2/4-OD Pressure Switch
- 2/4-OD Pressure switch poor electrical connection
- 2/4-OD Pressure switch circuit is open or shorted
Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shockP1782 DODGE Description The pressure 2/4-OD Pressure Switch is part of the pressure switch of the transmission. The pressure switch are located in the solenoid assembly. The switch provide input information to the Transmission Control Module (TCM). The switch will inform to the TCM is pressure exist in a specified hydraulic circuit. the TCM uses this information to verified that the solenoids are working or not.

P0700 DODGE - Transaxle Control System Malfunction

Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Driveability problems
- Transaxle shifting problems

Possible causes - Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module

P0700 DODGE Description The transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transaxle controls.
CLEAR THE CODES AND SEE IF IT RESETS. MOST LIKELY NOT A PROBLEM

The Transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. If any malfunction is detected, the TCM informs the PCM by sending a signal (P0700 code). P0700 means that a code has been set in the TCM. This code is for information ONLY. If this code is present, check for transaxle codes. So basically, the P0700 code is telling you to check the TCM for a transaxle DTC. The TCM can not turn on the check engine light so it has the PCM do it. The dealer probably saw the code P0700 and went to the TCM and pulled out the code stored there telling them the Transmission Solenoid Assembly (TSA) is bad.

I hope this helps....let me know if I can assist further !!

Because it is not starting, you should replace the Crankshaft sensor (above the oil filter, back of the engine)-it will cause a P0700-I have a 99 SL2, 178,000 miles

The dealer probably saw the code P0700 and went to the TCM and pulled out the code stored there telling them the Transmission Solenoid Assembly (TSA) is bad. This is a good example of understanding what the codes actually mean. If the manual you looked at said the TCM is bad and to replace the TCM when you see a P0700, then it is wrong.

P0700 JEEP - Transaxle Control System Malfunction
The transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transaxle controls.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Driveability problems
- Transaxle shifting problems

Possible causes
- Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module

Tech notes: Since the P0700 is just and informative code, check the TCM for more codes to resolve the problem. So you'll have to have the dealer or another qualified shop/technician pull the transaxle codes from the TCM and go from there.

Good luck (remember to rate this answer)

its a code in the eng computer he needs to scan for trans codes

(DTC) CODE # P0700....Transmission Control System (MIL Request)

Translation: Transmission Control Module (TCM) Malfunction or Failure.

P0700 Information Code

The Transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. If any malfunction is detected, the TCM informs the PCM by sending a signal (P0700 code). P0700 means that a code has been set in the TCM.

This code is for information ONLY. If this code is present, check for transaxle codes.


P1776: Solenoid Switch Valve Latched in Low/Reverse Position. The TCM monitors the L/R solenoid to ensure that the fluid transfer happens. It uses a Pressure switch to verify this. Usually this code is set by a switch that is stuck or a solenoid that is not mechanically operating.

A transmission shop would be better suited for this type of work.

So basically, the P0700 code is telling you to check the TCM for a transaxle DTC. The TCM can not turn on the check engine light so it has the PCM do it. It needs to be scanned with trans capable scanner to see what the trans code or problem is. You should have 1st, 2nd, and Reverse because the car is operating in limp-mode. Since you said the speedometer doesn't work, my guess would be a faulty (VSS) vehicle speed sensor.
