Mazda FW6A-EL

Transmission general data

The 6-speed FWD automatic transmission FW6A-EL with the east-west mounting was developed by Aisin for Mazda. This transmission was installed on Mazda CX-5 with the 2.0 liter engine, Mazda-3, Mazda-6. In terms of design, this transmission is very similar to the U660E transmission produced by AisinWarner. This transmission is considered to be the main competitor of ZF 6HP19-21. The FW6A-EL transmission has the torque converter with a double lock-up clutch that helps to accelerate the transmission faster and with higher efficiency. However, frequent usage of kick-down may lead to failures. This transmission employs reliable Aisin solenoids – linear type solenoids with anodized manifold, which is built into the solenoid body.

This transmission is a “rare guest” in the repair services, repair specialists mainly change oil and filter. It is recommended to change ATF after reaching the mileage of 100 thousand kilometers, and then every 50-60 thousand miles. It is required to monitor ATF transparency regularly, because with aggressive driving style ATF may get contaminated much earlier. In rare cases, transmission specialists face the problem when the torque converter lock-up damages the pump. The issue is expressed in vibrations and leakages through the pump seal. In this case specialists not only replace the seal, but also repair the torque converter and replace clutches. Another problem, similar to the issue in U660E, is wear of the case center bearing. This problem occurs when drivers get carried away with the kick-down on cold oil. One more typical problem of this transmission is damage of the double drum High/Low. After running 100 thousand kilometers it is also recommended to monitor the ATF temperature and the heat exchanger operation, similar to VW problems with the TF60-SN transmission. In old cars repair specialists advice to clean the heat-exchanger during full ATF change, to ensure reaching of 300 thousand kilometers mileage before the overhaul.
