Honda Odyssey Transmission Problems & Overview

The second generation 1999-2004 Honda Odyssey was designed to be reliable and family-friendly. They got the usability part right, with power sliding doors, a fold-into-the-floor 3rd row seat, and side airbags. Unfortunately, the reliability bit wasn’t as well executed, because many owners experienced complete transmission failure due to faulty components used in the Honda B7XA 4-speed automatic, and Honda BYBA 5-speed automatic transmissions.

Honda claimed the faulty transmission parts were manufactured by outside suppliers. “Obviously, these components were not made to specification,” Honda spokesman Mike Spencer said. He went on to explain that Honda engineers had identified the root of the problems a few months prior, and have since redesigned the transmissions. “The four-speed models were afflicted with a bad bearing that could break apart, scattering fragments of metal that clogged fluid passageways in the transmission, causing it to shift erratically”.

Regarding the later 5-speed BYBA transmission problems, Spencer stated “The five-speed models typically were damaged by premature wear of the third-gear clutch pack. As the clutch friction material abraded, it scattered bits inside the transmission case, clogging fluid lines and causing erratic shifting. Drivers might suffer slipping, poor or no shifts, or sudden down-shifts from 5th gear to 2nd gear”.

But wait, there’s more! In certain situations, a second 5-speed BYBA transmission problem can arise, in which case 2nd gear itself would overheat and break. If this happens, the transmission would completely lockup, and your Odyssey will come to a sudden halt.

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

2004 Honda Transmission Recall

Back in 2004, Honda was forced to admit there was a problem, and recalled some 1.1 million vehicles, at a cost of $153 million dollars.

The recalled Honda models included:

  • 2002–04 Odyssey
  • 2003–04 Pilot
  • 2001–02 Acura MDX
  • 2003–04 Accord V–6
  • 2000–04 Acura 3.2 TL
  • 2001–03 Acura 3.2 CL

2006 Honda Transmission Class Action Settlement

Honda settled a class-action lawsuit over the matter in 2006, where they were accused of misleading consumers by selling them vehicles with defective transmissions. Naturally, Honda denied the charges, and settled so they wouldn’t have to admit there was actually a defect.

1999–2001 Honda Odyssey owners that were covered by the lawsuit were given an extension to their transmission warranty from the date they first purchased the van, which amounted to 93 months/109,000 miles (whichever comes first). The plaintiff’s lawyers also got nearly $5.5 million, plus expenses. However, a majority of the Odyssey’s covered by the lawsuit had already exceeded the time/mileage limits of the extended warranty. So these owners were forced to pay the $2,000-$4,000 repair bills themselves.

Honda Odyssey Recalls

Recall ID – Honda: P30 / NHTSA: 04V176000 – 2002-2004 Odyssey


After numerous customer complaints, Honda recalled the 2002-2004 Odyssey because certain operating conditions can cause the transmission to overheat. If this happens, extreme heat buildup between the countershaft and secondary shaft second gears, could result in broken gear teeth or complete gear failure.


If the internal components heat up to the point that the 2nd gear breaks, the transmission could lockup, bringing your minivan to a sudden halt, and possibly cause you to loose control.


On vehicles with less than 15,000 miles, Honda dealers were instructed to modify the oil cooler return line so that it provided more lubrication to the second gear. For vehicles with over 15,000 miles, dealers would look for discoloration on the gears, which signaled that overheating had already occurred. If overheating damage was found, the entire transmission would have been replaced. If no damage was found, the dealer would have simply modified the oil cooler line. Owners can contact Honda at 1-800-999-1009 (refer to Honda Odyssey recall P30). Or the National Highway Traffic Safety Administration at 1-888-327-4236 (refer to recall 04V176000). This recall was issued on April 21, 2004

Recall ID – Honda: S73 / NHTSA: 12V573000 – 2003-2004 Odyssey


On certain Odyssey vans, the interlock lever inside the ignition switch may become deformed, allowing the ignition key to be removed without the gear selector being in the Park position.


If the ignition key is removed before the transmission is shifted into Park, the Odyssey could rollaway unexpectedly, increasing the risk of injury or property damage.

Dealers were instructed to install an updated shift interlock lever, or an entirely new ignition switch. Owners can contact Honda at 1-800-999-1009 (refer to Odyssey recall S73). Or the National Highway Traffic Safety Administration at 1-888-327-4236 (refer to recall 12V573000). This recall began on Issued February 7, 2013

Honda Odyssey Technical Service Bulletins (TSB)

2011-2012 Odyssey – TSB 12-064 / 10046880


A software issue can cause a slight hesitation, a surge, or a judder as the transmission shifts into 2nd, 3rd, or 4th gears.

To correct this issue, the PGM-FI software will have to be updated to the latest version, and the ATF will have to be changed as well.

  1. Ok so my 2004 honda odyssey spit fluid on the freeway and now the transmission fluid looks and smells burnt and tcs light is on and check engine light is on too

  2. 2004 odyssey, bought w 205k miles, love the car. serviced tran on a regular basis, major trans failure at 315k. Doing aamco complete rebuild w warranty, would an external return inline filter be good? Thanks for the help.

  3. If your 1999 – 2004 Honda Odyssey start slipping in 2nd or 3rd gear like it’s revving in neutral while you’re driving it’s because you need to replace the 3rd and 4th gear pressure switches are the 1999 to 2001 Honda Odyssey there’s only four speeds so you need to replace the 2nd and 3rd gear pressure switches. Do not forget to buy the crush washers for each it’s about $30 and $40 for each pressure switch. The problem you were experiencing on the slip is called flaring I just discovered this and found the fix a few weeks ago try it trust me it works. Also do a transmission fluid flush and also there are two solenoids on the transmission that you need to clean out. Depending if you have a 4 speed or 5 speed transmission they will be either to solenoid on top of the transmission or one on top and one on the front of the transmission. You need to remove it and clean out the metal mesh screens with brake cleaner and reinstall

  4. I have a 2002 Honda Odyssey with only 88,115 miles. In the last month, three times, the car has hesitated like skipping a beat while the motor whirred for a second as if you were stepping on the gas to rev it up or to pass. It’s almost like while you’re driving along you put it in neutral for one second and that’s the feeling and sound I have gotten in this early stage of some problem. I figured after all these years of living that it must be the transmission. It has been inspected and the computer checked as well as the hoses, belts and fluids etc. a week ago and no computer problem with the general hook up of the analysis device.

  5. A week ago, my 2003 Honda odyssey, would not drive in any gear including reverse. It would rev but not move. It has about 90,000 miles on a replacement tranny. The dash “dummy” switch also activated showing a problem with he transmission. I assume this is a major transmission issue but am wondering if there are some less expensive failures that might cause this and whether it is worth attempting a fix. I would estimate the car is worth about 2000.00 with a working transmission and about 600.00 for parts.
