DTC P0700: Transmission Control Module (TCM) Requested MIL Illumination
The transmission control module (TCM) uses the (GMLAN) to signal the engine control module (ECM) that the TCM is requesting malfunction indicator lamp (MIL) illumination. This happens when the TCM has determined that a failure affecting emissions has occurred in transmission control system. When the ECM receives the message from the TCM, DTC P0700 will set.
DTC P0700 can not be cleared from the ECM until the related TCM codes have been cleared.
This is something best left to a qualified repair shop , doesn't need to be the dealer ! AMMCO could fix it . This code is telling that other codes are stored in the transmission control module . Need a professional type or factory scan tool to check these . As to how much it will cost , no telling without knowing the codes in the TCM !

Testimonial: "I went and had autozone check the code and it was the purge solenoid valve, and the EVAP canister."

    According to P0700: Transmission Control Module
    You have other problems , auto zone can not access these codes .

Generic indicator for the TCM. More specific codes are in the TCM, which will probably need the dealer to scan.

You don't say which engine your's has ! Or which transmission .

You need to have TCM checked for codes .

I get code P1775 and P0700


Hi.

P1775 is the most relevant code. It means Solenoid valve latched in torque convertor.

P0700 is consequence of the P1775 code. P0700 means that there is an additional code stored in the TCM (transmission control module). The TCM stored code is probably related to the same problem. TCM codes can be pulled out at the car dealer or at an authorized garage. On this see: I get code p0700 after an OBDII scan.

P1775 is often coming with misfire codes.

P1775 means that the TCM detects that the solenoid valve located in the valve body (inside transmission pan under the filter) is not in the expected position (valve has two positions LR and TCC).
This cause rough shifting and driving problems.

Sometimes it is possible fixing the problem by resetting TCM and ECU. This is done disconneting battery cable (ensure you have anti-theft code if needed).

However, if a P1775 occurred, that means that there had been a solenoid valve malfunction, and problem must be fixed.

The first thing to do is replacing transmission fluid, and if needed also the filter. If the fluid level is poor, or if fluid is dark brown and satured with metal particles, that can cause solenoid valve malfunction.

If replacing the fluid does not help, then the most common problem causing the P1775 code is a defective solenoid in the solenoid pack.

Transmission shift solenoids are located in valve body, and they can be tested reading Ohms with a multimeter.

If that does not fix the problem (usually it does), the mechanic will proceed testing wiring to solenoid pack, TCM and solenoid valve, to find the reason of malfunction. Most common problems causing P1775 are related to tranny fluid and solenoid pack.

For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission. If the TCM compatible scan tool will not communicate with the Transmission Control Module then that is a good indication that there may be a fault with the TCM itself.

Tech notes Since the P0700 is just and informative code, check the TCM for more codes to resolve the problem.

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

What do i need to replace to fix error code p0700 on a 2002 dodge intrepid


(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. 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.

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

Car does not run ,I check the code ,it is P0700


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 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. 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.

Error P0700. What is the cause? How to repair it?


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)
