The Honda PJD4, or i-Shift, 6-speed robotic transmission was produced at the Japanese plant from 2005 to 2009 and installed in the 8th-generation Civic 5D, paired with the 1.8-liter R18A engine. This single-clutch robotic transmission has a rather poor reputation.
i-Shift family: PJD4, SF7M.

Disadvantages of the Honda PJD4 gearbox
- This transmission is prone to problems and often requires repairs after 50,000 km;
- The most common problem here is wear of the clutch actuator brushes;
- Bending of the clutch fork and breakage of the actuator rod are also common in this transmission;
- By 100,000 km, the clutch assembly usually requires adaptation or replacement;
- The weak points of this robotic transmission are its control module and clutch hydraulic cylinder.
