Transmission general data

First of all Japanese engineers pay much attention to the reliability rate when manufacturing automatic transmissions. Reliability became an important factor when Japanese specialists decided to produce 4-speed automatic transmission M4TA (released in 1997) without planetary gears. The advantage of this solution is considered to be improved reliability. But it the same time it should be noted, that such transmissions have a massive size, therefore it complicates the process of repair. The automatic transmission M4TA was installed on Honda Civic, Odyssey, Prelude, Accord, crossover CRV. The maximum engine capacity allowed for this transmission equals to 2,4 liters.

Technical issues and repair guidelines

As it has been mentioned above the automatic transmission M4TA is notable for its enhanced reliability. The car owner only needs to regularly change the oil with filter elements. It is required to use high-quality transmission oil, that preserves bushings and friction clutches from wear-out.

In most cases it is required to perform the overhaul after travelling 300.000 kilometers or more. At the same time it should be noted, that improper operation of the transmission and aggressive driving behavior may lead to frequent malfunctions resulting in the overhaul after running 100.000 kilometers and even earlier. Therefore it is necessary to point out, that this transmission is mainly intended for operation in urban environment.

In the list the most frequent malfunctions we should point out problems with seals and rubber-covered gaskets. Rubber covered linings may get out of order rapidly leading to oil leakages. In this case it is required to replace rubber covered gaskets and seals. Implementation of these repair procedures may be troublesome because of the transmission dimensions. The pan disassembly is a complicated procedure and should be performed in the service facility. In the process of overhaul specialists perform the valve body state check, replacement of friction clutches and drums. In some specific cases it is required to replace burnt clutch. Generally this transmission makes a good impression, distinguished by reliability and repairability.
