Technical issues and repair guidelines

This transmission is very reliable as all RWD Aisin transmissions. The repair of this transmission in most cases includes oil and filter replacement.The transmission reassembly requires the repair kit of gaskets and seals with valve body spare parts, which are ordered because of sealing rings, which wear out earlier than all other spare parts and gaskets.


The electrical part of this transmission is maximally unified: the valve body has 3 simple and invincible On-Off solenoids, 3 interchangeable linear solenoids ( А, C, D solenoids according to the manual), responsible for an ideal gear shifting and a linear solenoid (B). Solenoids usually are quite reliable, but in case of any issues related to the valve body, solenoids are considered the main cause of these problems. Aisin valve bodies produced after 2009 are notable for enhanced durability and are almost not ordered for replacement.
