I have an 2004 Acura RSX with an Auto trans. The D indicator on the dash blinks when I start the car. Car will not leave first gear but will go in reverse and park. Just trying to figure out how I would properly diagnosis this before jumping the gun and trying to replace the solenoid. Another issue that has occurred with it is my car won’t always start and I have to keep trying to start it and it will click once every time I try. But will eventually start after a few tries. Only code shown on the OBDII READER is p0753. Car has about 190K miles, Tranny was replaced with a used one about a 1 1/2 years ago.

Clicking.....First thing is to charge and test battery.

DTC P0753: Problem in Shift Solenoid Valve A Circuit

NOTE: Record all freeze data before you troubleshoot.

1. Turn the ignition switch OFF.
2. Disconnect PCM connectors A (31P) and C (22P).
3. Turn the ignition switch ON (II).


Open In New TabZoom/Print



4. Measure the voltage between PCM connector terminals C6 and A23 or A24.
Is there voltage?
YES - Repair short to power in the wire between PCM connector terminal C6 and the shift solenoid valve A.
NO - Go to step 5.
5. Turn the ignition switch OFF.
6. Disconnect the shift solenoid harness connector at the transmission housing.


Open In New TabZoom/Print



7. Check for continuity between PCM connector terminals C6 and A23 or A24.
Is there continuity?
YES - Repair short to ground in the wire between PCM connector terminal C6 and the shift solenoid harness connector.
NO - Go to step 8.
8. Connect the shift solenoid harness connector.


Open In New TabZoom/Print



9. Measure the resistance between PCM connector terminals C6 and A23 or A24.
Is there 12 - 25 ohms?
YES - Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
NO - Go to step 10.
10. Disconnect the shift solenoid harness connector.


Open In New TabZoom/Print



11. Check for continuity between PCM connector terminal C6 and the No. 5 terminal of the shift solenoid harness connector.
Is there continuity?
YES - Check the shift solenoid valve A, and check for an open in the shift solenoid harness in the transmission.
NO - Repair open in the wire between PCM connector terminal C6 and the shift solenoid harness connector.

Be careful with that flow chart....We don't call them 'trouble trees' for nothing. Glean from it how the system works and use logic to test.

Will do, pulled out my meter, getting ready to test them soon. Just Hoping it’s not the solenoid, but feel it is oh well
