Up for sale is a complete 6th gear pulled from a 2015 Honda Civic SI manual transmission. This is the full kit used to add 6th gear to 5 speed transmissions. This works just like the 06-11 SI and 04-08 TSX kit but uses a longer gear ratio so rpms will be even lower on the highway. Ratio for this set up is .647 where is older one is .659. Gear set up is in good used condition and ready to be installed into a 5 speed trans. Great for Element/CR-V owners to convert their 5 speed to 6 speed. Please look at the pictures carefully. Please email with any questions before purchasing.
