JDM Honda Accord V6 Transmission – MRDA 5-Speed Automatic

If the automatic in your Accord V6 is slipping or failing, this JDM Accord V6 transmission offers a low-mileage replacement. Honda paired a 5-speed automatic with the 3.0L J30A in the seventh-generation Accord, as Wikipedia’s Honda Accord history explains. In addition, this unit comes with the torque converter, starter and sensors. Better yet, the 11 photos show the actual transmission you’ll receive.

About This Accord V6 Transmission

This transmission carries the Japanese-market code MRDA and serial number 3003207. Specifically, it’s a 5-speed automatic for front-wheel-drive V6 Hondas and Acuras. Since it comes from Japan, it typically shows lower mileage than a U.S. used unit of the same age. Finally, it includes a 30-day warranty.

Accord V6 Transmission Fitment

• 2003–2007 Honda Accord V6 (3.0L J30A), automatic
• 2004–2006 Acura TL (3.2L J32A), automatic

However, Honda changed the torque converter and drive plate setup for the 2006–2007 Accord V6. For that reason, send us your VIN, and we’ll confirm the right setup for your year before you order.

MRDA vs. BAYA and MAYA Codes

U.S. Accord V6 transmissions carry codes such as BAYA or MAYA, while Japanese-market units like this one carry MRDA. Although the code differs, the transmission shares the same basic 5-speed design. Still, compare the connectors, range sensor, and torque converter with your original unit before installation.

How to Install This Accord V6 Transmission

1. First, compare the range sensor and connectors, and transfer your original sensors if they differ.
2. Next, confirm the torque converter matches your flexplate, especially on a 2003–2005 car.
3. Then, flush the transmission cooler lines, because old debris can damage a replacement unit.
4. After that, fill the transmission with genuine Honda ATF DW-1 only.
5. Finally, clear any codes and let the computer relearn shift points during the first drives.

Most importantly, keep your original transmission until the swap is complete, so your installer can compare parts side by side.
