Acura MDX Transmission Problems & Overview

Based on the same “Global Midsize” platform that underpins the Honda Accord, the first-gen Acura MDX debuted in 2000 for the 2001 model year. This was Acura’s first SUV to be designed and built in-house (their Acura SLX was based on the Isuzu Trooper), and it used a more powerful version of the Accord’s V6.

The 2nd-gen 2007-2013 Acura MDX got a powerful 300-hp 3.7L V6, along with the option of Acura’s much lauded Super-Handling AWD (SH-AWD) system.

The 3rd generation debuted in the summer of 2013, at which point a staggering 692,710 MDX’s had been sold since 2000. This impressive sales tally made it “the best-selling three-row luxury crossover of all time”, and it continues to be the second best-selling midsize luxury CUV behind the Lexus RX.

Does something seem wrong with your MDX? Let’s look at some of the most common transmission problems, and see what you can do to get your SUV back on the road.

Acura MDX Recalls

2014 MDX AWD – 13V571000 / JC8


American Honda Motor Co., Inc. recalled certain 2014 MDX AWD models that were manufactured between May 6, 2013, through October 14, 2013. It seems that the bolts that attach the drive shaft to the automatic transmission transfer assembly may not have been properly tightened. As a result, the bolts could loosen possibly allowing the shaft to detach.


If the drive shaft detaches while driving it could cause excessive noise and possibly damage the vehicle, increasing the risk of a crash.


Honda began notifying owners in December 2013, and dealers were instructed to inspect and tighten the drive shaft attaching bolts as necessary, free of charge. Owners may contact Honda at 1-800-999-1009 or visit their website at Be sure to refer to Honda’s recall number: JC8. Owners can also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236

2003-2006 MDX – 12V573000 / S74


Honda is recalling certain 2003-2006 Acura MDX SUVs that were manufactured from November 26, 2001, through August 30, 2006. It seems that the interlock lever of the ignition switch may deform, which can allow the interlock function of a vehicle with an automatic transmission to be defeated.


Removal of the ignition key when the gear selector of a vehicle with an automatic transmission has not been shifted to the park position can allow the vehicle to roll away, increasing the risk of a crash that could result in serious injury and/or property damage.


Honda began notifying owners in February 2013, and instructed their dealers to install an updated shift interlock lever and, if necessary, replace the ignition switch, free of charge.  Owners may contact Honda at 1-800-999-1009, be sure to refer to the Acura recall number: S74.

2001-2002 MDX – 04V176000 / P31


According to the recall, certain operating conditions can result in heat build-up between the countershaft and secondary shaft second gears in the automatic transmission, eventually leading to gear tooth chipping or gear breakage.


Gear failure could result in transmission lockup, which could result in a crash.


This recall began on April 21, 2004, and Honda issued the following repair procedures: On vehicles with 15,000 miles or less, the dealer was instructed to update the transmission with a simple revision to the oil cooler return line to increase lubrication to the second gear. On vehicles with more than 15,000 miles, the dealer was supposed to inspect the transmission to identify gears that have already experienced discoloration due to overheating. If discoloration exists, the transmission was to be replaced. If discoloration is not present, the dealer will perform the revision to the oil cooler return line.

Owners can contact Acura at 1-800-382-2238, referring to recall number: P31. Owners can also contact the National Highway Traffic Safety Administration’s auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).

Acura MDX Technical Service Bulletins (TSB)

2007-2009 MDX – TSB 12-029


A shudder from the torque converter lock-up clutch may be felt while driving between 20–45 mph. To minimize the opportunity for the judder to occur, a software update for the transmission is available.


This AT software update is available free of charge to all affected vehicles regardless of its age or mileage. However, if the judder returns after the transmission software is updated, the torque converter may need to be replaced. American Honda did extend the warranty on the torque converter in affected vehicles to 8 years from the original date of purchase or 105,000 miles, whichever comes first.

If you have any questions about this warranty extension, please call Acura Client Relations at 1-800-382-2238, and select option 4. US owners can also locate a dealer online at Owners in US territories, please contact your local dealer/distributor.

2003-2004 MDX – TSB 06-003


If your MDX shudders or vibrates between 35 and 40 mph, there’s a good chance that the torque converter is faulty.


Replace the torque converter, or the torque converter and the transmission, and update the PCM with the HDS. NOTE: The PCM software must be updated in order to complete the repair.
