TSX 5th & 6th Gear Parts List
Here is the list of parts that we have found that you need in order to install a TSX 5th and 6th gear. These are longer than the standard RSX or Civic Si gears so you will get better gas mileage. We picked the gears from the 04-08 TSX because they are a touch longer than the 09+ TSX. This will also be the parts that you need if you want to upgrade your 5-speed transmission to a 6-speed. If you have part numbers to add or something we have missed, please email webmaster@clubrsx.com and we will get it verified and added.
