Show original supplier description
The Honda PNN4 is a 6-speed manual transmission engineered for 2.0L K-series engine platforms, specifically 2006-2011 Civic Si models. It is a vital component for maintaining drivetrain performance in these vehicles. For proper installation and to maintain performance, you must install a new clutch, pressure plate, and slave cylinder. Additionally, the flywheel must be turned prior to installation. Failure to replace the filter and fluids, or failure to properly flush transmission cooling lines, will void the transmission warranty completely. This unit is sold as a used part and requires careful verification of fitment. It is the buyer's responsibility to match the part number to their specific application before purchasing to avoid restocking fees. Professional installation is highly recommended to ensure all components are seated and the system is properly filled with fluid.
