Summary: On some mini vans, sport utility and passenger vehicles, 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.
Consequence: Gear failure could result in transmission lockup, which could result in a crash.
Remedy: On vehicles with 15,000 miles or less, the dealer will 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 will inspect the transmission to identify gears that have already experienced discoloration due to overheating. If discoloration exists, the transmission will be replaced if discoloration is not present, the dealer will perform the revision to the oil cooler return line. The recall began on April 21, 2004, for pilot, odyssey, and mdx owners. Owners of the accord vehicles will start receiving letters on June 28, 2004, and on June 29, 2004, for owners of the tl and cl vehicles. Owners should contact Honda at 1-800-999-1009 or Acura at 1-800-382-2238.

Has your Acura been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. Recall repairs are free.
