Your Honda Fit Hybrid GP5, Vezel, Jade etc do not have automatic transmissions, they have manual transmissions and the hydrostatic actuator in the picture above is responsible for electronically engaging and disengaging the clutch when shifting gears. The unit uses Dot4 brake fluid the same way conventional manual transmissions do. This fluid needs to be changed regularly to avoid catastrophic failure of components. If you haven't serviced your dual clutch system since you imported your vehicle, you are sitting on a time bomb waiting to explode. Some are even unfortunate as their transmissions fail on the way from Tanzania. Let's talk about your next service. 0783071319
