BACKGROUND
A judder from the torque converter lock-up clutch may be felt while driving between 20 and 60mph. The problem is typically diagnosed as a bad torque converter. American Honda investigated the judder and found that the torque converter was not causing the judder; rather, it was caused by deteriorated transmission fluid. The transmission fluid deteriorates quicker than expected when it is exposed to intermittent high heat loads under specific driving conditions. American Honda is working on a software update that will maintain the transmission fluid temperature within the desirable range under all driving conditions and eliminate the potential for this judder. American Honda will revise this service bulletin when the software update is available.
Until the software is released, the judder can be fixed by flushing the transmission fluid as indicated in the FLUSH PROCEDURE. Make sure the customer is aware that this is a temporary fix and he or she will have to return once the software is available to make sure the transmission judder is resolved.
NOTE: American Honda defines flushing the transmission as draining and filling the transmission with a drive cycle three times to help make sure the deteriorated fluid is removed. There are other aftermarket flush systems available, but American Honda does not recommend using them.
TEMPORARY CORRECTIVE ACTION
Take an automatic transmission snapshot and review the data. For more information about capturing and interpreting the data, refer to the job aid Torque Converter Clutch Shudder and Vibration and the Tech2Tech video “Interpreting Torque Converter Judder Snapshot Data.”
Once it is confirmed that the judder is coming from the torque converter, flush the transmission three times as indicated in the FLUSH PROCEDURE. This is a temporary fix that does not affect the durability or life span of the torque converter until the software is developed.
NOTE: There is no need to call Tech Line before undertaking this ATF flush repair.
PARTS INFORMATION
Part Name | Part Number | Quantity |
Genuine Acura ATF DW1 | 08200-9008A | 10 |
Washer, Drain plug (18 mm) | 90471-PX4-000 | 1 |
Washer, Sealing (24 mm) | 11107-PWA-300 | 1 |
FLUSH PROCEDURE
NOTE: The term “flushing” refers to repeatedly draining and filling the transmission with Acura Genuine
ATF-DW1. Other aftermarket flush systems are available, but American Honda strongly recommends that you avoid using them on any Acura vehicles.
1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or Neutral) until the radiator fan comes on, then let it idle.
2. Position the vehicle on a lift and turn off the engine.
3. Remove the ATF filler bolt and sealing washer.
4. Raise the vehicle and make sure it is securely supported.
5. Remove the drain plug and drain the ATF.
6. Install the drain plug and original washer and torque it to 49 m (36 lb-ft).
7. Lower the vehicle and fill the transmission with 3 US qts (3.1 L) of ATF-DW1 through the filler hole. NOTE: Do not use non-Acura ATF because it can affect shift quality.
8. Install the ATF filler bolt and original sealing washer and torque it to 44 m (32 lb-ft).
9. Check that the fluid is filled to the proper level.
10. Raise the vehicle and make sure it is securely supported.
11. Start the engine.
12. Press the brake pedal and shift to Drive.
13. Release the brake pedal. Press the accelerator pedal and bring the speedometer up to 50 mph. Make sure the transmission shifts through the first three lower gears and into fourth gear and the torque converter is locking up.
14. Apply the brakes to stop the front wheels.
15. Shift to Reverse, then Neutral.
16. Repeat the shifting procedure (steps 12 through 15) four more times.
17. Turn off the engine.
18. Repeat the above drain, fill, and shifting procedure (steps 2 through 17) one more time.
19. After the second refill and drive cycle, drain the transmission.
20. Install the drain bolt with a new washer and torque to 49 N.m (36 lb-ft).
21. Fill the transmission with 3 US qts (3.1 L) of ATF-DW1.
Automatic Transmission Fluid Capacity
AWD: 3.3 US qts (3.1 L) at change
2WD: 3.3 US qts (3.1 L) at change
NOTE: Do not use non-Acura ATF because it can affect shift quality.
22. Install the ATF filler bolt with a new sealing washer and torque the bolt to 44 m (32 lb-ft).
23. Clear any DTCs set while driving on the lift.

i-HDS Diagnostic Software and J2534 Reprogramming Software
Honda J2534 Pass-Thru User Guide

i-HDS Diagnostic Software and J2534 Reprogramming Software
American Honda Motor Co., Inc. ("Honda") offers the i-HDS (Honda Diagnostic System) software suite for the diagnosis and repair of electronic systems on Honda and Acura automobiles, and for the reprogramming of electronic control units (including, but not limited to, ECMs and PCMs). This software provides access to all Honda and Acura vehicle systems (access to the immobilizer security system requires a Security Professional level software subscription and Vehicle Security Professional [VSP] registration with NASTF). To use the i-HDS software, you need to purchase one of our convenient subscription options. In addition, you will need a pass-thru Vehicle Communication Device (VCI) that is compliant with SAE J2534-1 and J2534-2 in order to communicate with the vehicle
Vehicle Communication Interfaces (VCI)
The i-HDS software supports the use of a generic pass-thru VCI that is compliant with SAE J2534-1 and J2534-2. However, Honda recommends the Denso DST-i or the Bosch MVCI for use on Honda and Acura vehicles, as Honda has worked closely with these manufacturers to ensure their hardware and our software interact safely and within the J2534-1 and -2 specifications, for both diagnostics and reprogramming. If you choose to use a generic VCI, please carefully consider the customer and technical support options you will receive from your chosen device supplier. Honda does not provide technical or customer support for generic VCI devices.
The VCI Application Table below lists devices that either are approved and supported by Honda or are known to have completed and passed an independent, exhaustive validation program with our i-HDS software suite.
VCI Name | Manufacturer | Version Information | Notes | |
---|---|---|---|---|
Firmware | J2534 API | |||
DST-i | DENSO | 2.02.0002* | 04.04 | This is the current generation VCI used by Honda and Acura dealers. Honda routinely validates the functionality and provides customer support for this device. |
DST-nano | DENSO | 2.02.0002* | 04.04 | This is the current generation VCI used by Honda Canada Inc. Honda and Acura dealers. Honda routinely validates the functionality and provides customer support for this device. |
MVCI | Bosch | 3.01.60* | 04.04 | This is the previous generation VCI used by Honda and Acura dealers. Honda routinely validates the functionality and provides customer support for this device. |
MongoosePro Honda | Drew Technologies | 1.9.5** | 04.04 | This company has completed an independent i-HDS validation and claims it to function with the i-HDS software. Honda does not provide ongoing validation, nor customer support for this device. |
d-briDGe Pro | Dearborn Group | 3.303** | 04.04 | This company has completed an independent i-HDS validation and claims it to function with the i-HDS software. Honda does not provide ongoing validation, nor customer support for this device. |
* These versions may have been superseded. Honda provides the latest supported versions to current i-HDS subscribers.
** Version used in validation program. See Terms and Conditions and Important Notice Regarding Reprogramming below for more details.
Reprogramming with the J2534 Rewrite Application in i-HDS
Included in the i-HDS software suite is a new reprogramming application called J2534 Rewrite. This application is made available to all subscribers of the i-HDS software suite and replaces the previous generation software, J2534 Honda Pass-thru Reprogramming Software.
This new application is compatible with generic VCIs that comply with SAE J2534. It must be used to reprogram any Honda/Acura vehicle equipped with ECUs that support reprogramming. Refer to the table below for legacy applicability for the programming of ECMs and PCMs. Though system dependent, late-model vehicles may be equipped with other ECUs that support reprogramming as well, e.g. ABS or VSA. J2534 Rewrite must be used to reprogram these control modules, as instructed in an applicable service bulletin.
As shown in this table, not all legacy Honda/Acura models are equipped with a reprogrammable ECM/PCM. Furthermore, all 2007 and later models not listed in the table are fully supported with this application.
