NO FORWARD OR REVERSE

2001 Mitsubishi Eclipse • 6 cylinder FWD Automatic • 131,000 miles

I have a 2001 Eclipse GT 3.0L. Recently while driving the car it went into neutral. I have no forward or reverse. The fluid is clean and not burnt which leads me to believe its electrical. I have seen a bunch of forums that talk about the same situation but no resolutions. Is there something I should check, ie speed sensors or some other sensors?

I would first check and see if you have any code's in the computer if it's electrical you should have some code's. Let me know the exact code number's if you have any.

P0760 and p0765 and an o2 sensor code that I do not remember off the top of my head. But unlikely both solenoids went out at the very same time. It seems to me that something else went bad and those codes where thrown because the solenoids where not getting the signals they needed or maybe I am wrong.

Here is the info on code p0760 and P0765.
TECHNICAL DESCRIPTION let me know what you find you could have a bad computer.

* When a malfunction of the shift solenoid C (Second solenoid) is detected, the transaxle control CPU inside the powertrain control module (PCM) outputs a malfunction signal to the engine control CPU in the PCM.

DTC SET CONDITIONS

Check Conditions, Judgment Criteria

* Second solenoid failure signal is input to the engine control CPU from the transaxle control CPU.

TROUBLESHOOTING HINTS (The most likely causes for this code to be set are: )

* Second solenoid failed.
* Open or shorted second solenoid circuit, or loose connector.
* PCM failed.

DIAGNOSIS

Required Special Tools
MB991502: Scan Tool (MUT-II)

STEP 1. Using scan tool MB991502, read the A/T diagnostic trouble code (DTC).

CAUTION: To prevent damage to scan tool M6991502, always turn the ignition switch to the "LOCK" (OFF ) position before connecting or disconnecting scan tool M6991502.

1. Connect scan tool MB991502 to the data link connector.
2. Turn the ignition switch to the "ON " position.
3. Check the A/T-DTC.
4. Turn the ignition switch to the "LOCK" (OFF ) position.

Q: Is the A/T-DTC is output?
YES: Refer to Automatic Transaxle Diagnosis - Trouble Code Descriptions Chart. See: Transmission Control Systems\Testing and Inspection
NO: If DTC P0760 is output again after the MFI-DTC has been erased, replace the PCM. Then check that the DTC P0760 does not reset.

TECHNICAL DESCRIPTION

* When a malfunction of the shift solenoid D (overdrive solenoid) is detected, the transaxle control CPU inside the powertrain control module (PCM) outputs a malfunction signal to the engine control CPU in the PCM.

DTC SET CONDITIONS

Check Conditions, Judgment Criteria

* Overdrive solenoid failure signal is input to the engine control CPU from the transaxle control CPU.

TROUBLESHOOTING HINTS (The most likely causes for this code to be set are: )

* Overdrive solenoid failed.
* Open or shorted second solenoid circuit, or loose connector.
* PCM failed.
