Technical issues and repair guidelines
The transmissions has much higher reserve on components than its German competitor and should operate at least 200-300 thousand kilometers before the first overhaul ( under the condition of well-timed ATF change). In case of frequent “kickdown” usage with a switch-on of controlled slipping of the lock-up clutch, the wear-out of friction elements occurs quite rapidly and contaminates the valve body, fluid and filter. The filter is made of plastic with a two-layer felt membrane and its better to change this part in a timely manner.
The oil and filter should be changed when there are any suspicions related to oil transparency. Such situations may occur after travelling 40 thousand kilometers or 80 thousand kilometers depending on driving style and adherance to the transmission warm-up rule before driving in winter time. Removal of the pan allow specialists to estimate the level of components wear-out and valve body contamination.
