DTC P0753 – How To Service an Accord TCC Solenoid

SHARE

Problems can arise from your automatic transmission in regards to your Torque Converter Clutch (TCC) Solenoid. When you are dealing with a Honda engine and transmission ECU, this unit can also be called the lock-up control solenoid assembly.

When this solenoid goes bad it can trigger the OBDII DTC trouble codes P0753 Shift Solenoid A Electrical. The P0753 Shift Solenoid ‘A’ Electrical issue is triggered when the ECU detects the transmission in a different gear than indicated.

Triggering this check engine light can cause sputtering or bucking in your Honda Accord. Extreme cases can lead to the transmission not shifting or leaving your vehicle stuck or stranded. The Honda Accord Transmission Control Module (TCM) responds to the Park Neutral Position (PNP) switch and put the transmission into the optimum gear.

Symptoms of DTC P0753

  • D4 gear indicator blinks
  • Vehicle does not shift smoothly
  • Does not shift into overdrive
  • Manually shifting your Honda allows you to drive it. (In D3 or D2)

Things to check first before you test your Torque Converter Clutch

  • Low transmission fluid
  • Dirty transmission fluid
  • Wrong transmission fluid type

If you have changed your transmission fluid and flushed it but this problem still persists, you can begin our How To Service an Accord TCC Solenoid guide here.

Today we’ll be showing you how to test, resolve and replace the TCC Solenoid in a 2000 Honda Accord 4 cylinder.

The TCC Solenoid or lock-up control solenoid assembly is found on the front of your transmission housing, directly underneath your ignition distributor.

Locate this solenoid and find the 2 pin weatherproof connector that connects the solenoid to your engine harness.

The two pin connector is secured to the transmission using a metal tab and push lock. To free this connector up so that you can access it, simply pull up on the back of the connector, or the part closest to you.

You will be pushing up on the bottom of this clip to release it from the metal tab, pull down on the entire connector to free this assembly. Go ahead and unplug the front oxygen sensor to give yourself a little more  operating room to test your TCC Solenoids.

Unplug your TCC solenoid to expose the connectors you will be testing. Shown is the engine side of the harness, which you will not need for the solenoid testing portion of our How To Service an Accord TCC Solenoid article.

Take the connector on the solenoid side and you will be testing to see if the lock up clutch engages inside the torque converter by sending power to PIN 1. Following the illustration above, use a wire to connect to your battery or use a device that is capable of sending power and ground to any pin, like our Power Probe here.

Performing our How To Service an Accord TCC Solenoid Guide is easy and straightforward using a voltmeter and a wire from your battery. First we’ll be testing the Shift Solenoid power by sending 12 volts directly to shift solenoid A or PIN 2 in our diagram. This pin should be yellow and once you send power to it you should hear your solenoids clicking over.

Next you will be measuring the resistance value between PIN 1 using a voltmeter, put the red lead of your meter to PIN 1 and ground the black lead on your transmission housing. The resistance value you should see here is 12 – 25 Ω.

If your solenoid checks out okay with these two steps, you can now move onto the removal section of our How To Service an Accord TCC Solenoid. Remove the TCC Solenoids by undoing the 3 10mm bolts that secure it to your transmission.

Next flip the unit over to inspect your solenoid o-rings, make sure they are clean and clear of any debris. Make sure that the o-rings still retain their sealing edges and that there’s nothing blocking the screens themselves.

If all these check out and your P0753 check engine light refuses to go away, it may be time to replace your Honda Accord TCC Solenoid. This item isn’t normally sold by Honda separately at the time of this writing, but can be found in the aftermarket segment using the following part numbers :

  • TCS4
  • 576501
  • 576501
  • TKS11

    • Hi Linsey, thanks for commenting!

      okay so.. your TCC solenoid is showing open? I would try swapping the ECU first to ensure that isn’t the root cause of the problem. Let us know how it turns out and if your Honda Accord is still giving you problems!

  1. will this great infomation work on a 1997 acord ex 2.2 v-tec the resson why i manual shift my automatic because with all the bolt=on mods it perform better than D-4 ALLTHE TIME.

BUT RUN LIKE A ROADRUNNER.I NOTICE WHEN I PUT MY HAND ON THE SHIFTER TO SHIFT TO 3 GEAR THE RPM START TO RISE AFTER THE THE SHIFT.CAN THIS BE THE SHIFT SOLENOID? BECAUSE THE GEAR PULL ALL THE WAY TO THE REDLINE THE ACCORD PRETTY FAST RUN LOW 15 SECOND IN THE 1/4 MILE AT98 MPH. I CAN USE ALL THE INFORMATION YOU CAN OFFER. THANK YOU. RETRIER ASE TECH

    • Hi David, thanks for reading!

      If your transmission is slipping in this manner, we would suggest flushing and replacing the transmission fluid before this test. This is especially true if you are manually shifting the transmission in your automatic transmission equipped Accord. Let us know how it turns out and we’ll be glad to assist you further!
