Honda transmissions differ completely from the rest of automatic transmissions, because Honda does not use planetary gears. Honda transmissions are not complex in terms of design, have larger dimensions and as a result considered to be more robust. But automatic transmissions produced by Honda also have some vulnerabilities related to electronic gear shifting control: friction discs, solenoids, and the valve body.

Technical issues and repair guidelines

The most well-known range of 4-speed 3-shaft transmissions M4TA - Honda (CR-V) with engines from 2 to 2.4 liters. Automatic transmissions Honda are notable for their simplicity and reliability. Because of this, many car owners neglect basic maintenance services such as ATF quality control and timely replacement of the filter. Subsequently it results in clogging of valves in the valve body and solenoids, oil starvation and rapid wear-out of sealing rings, frictions and bushings. 300-400 thousand kilometers is considered to be a standard mileage before the first overhaul for these Honda transmissions.


Repair procedures

The torque converter (TC) is the first component to be repaired in Honda automatic transmissions. A major repair with reassembly starts with change of transmission fluid and replacement of a metal filter. The main external filter is usually installed by specialists on old transmissions.The repair of this family of transmissions with the filter is performed with the help of ordered repair kit of gaskets and seals with friction elements and steel discs. Friction elements are frequently replaced separately and steel discs as a full kit. Masterkit is the fullest repair kit of friction elements and steel discs with kit of gaskets.

Honda friction components usually operate for a long time, but after exhausting an enormous resource of frictions (above 300 thousand kilometers) or when these elements are soaked with burnt oil, then the change of all frictions would be the best option.Worn-out switching solenoids of linear pressure and the clutch lock-up solenoid are commonly replaced during repair procedures. The design of solenoids includes anodized plate element, which is likely to wear. This component is changed after running over 200 thousand kilometers.
