Honda Odyssey Transmission Slipping and Case Repair Service
The Honda Odyssey was introduced in 1995 with a 2.2L or 2.3L engine and a four speed automatic overdrive transmission. Originally, we only saw a handful of these vehicles with transmission failure, but in 1999 a new model was introduced with a 3.5 L V-6 engine. These overdrive equipped Odysseys are known for the transmission slipping and problems with forward gear engagement. In 2002, the 3.5 L V-6 engines were mated to a five speed automatic transmission, and variations of this unit are still commonly seen today. The five-speed models have introduced a new collection of problems, while retaining many of the inherent design flaws common in many Honda and Acura cars and SUVs. Many Odyssey transmissions with high mileage have worn out cases, caused by the bearing which supports the gear shaft slowly wearing out the bore area within which it is installed. This can cause misalignment of transmission fluid feeding tubes that feed hydraulic pressure into the gear shaft to engage the clutch drum. When an Acura or Honda transmission is remanufactured, the original cast aluminum case should be professionally machined so that a wear-resistant forged aluminum or steel sleeve can be installed. A Dealer provided replacement will contain only the stock aluminum case as opposed to a wear resistant sleeve, which makes overhauled transmission preferable.
If the case bore was worn, the bushings within the gear shafts are usually worn as well, so should be replaced. In some situations, 2 bushings can be pressed into the shaft, providing a better seal.
Honda Odyssey Engine or Transmission Problem
If the engine is running above idle rpm, and you are not moving, you have a transmission problem. How smoothly the engine is running does not inherently affect the transmission operation, so a tune up is not the problem. A poorly running engine, however, could be caused by electronic engine controls such as throttle position sensor, mass airflow sensor, or manifold air pressure sensor. This can affect the way the transmission shifts because it uses these same electronic engine sensors to control shift timing and firmness. If the transmission seems to have problems, but is not slipping out of gear, proper evaluation of the electronic engine controls should be performed. Performing an accurate transmission diagnosis can only be achieved when the performance of the other sensors is correct. This is the first step Suburban Transmission performs in its diagnostic evaluation, eliminate other possible solutions.
