Looking for anyone interested in a used transmission for a 9th Gen Civic Si. This came with only 94,xxx miles on my 2015 Civic Si (purchased salvage), and replaced with another one.

Shifts well into gears, HOWEVER, 2nd gear synchros are almost completely shot resulting in difficulties engaging that gear. For the 5 months I drove the car with this transmission, I was able to consistently shift around 1,900 RPM into 2nd without grinding, but every other RPM caused an awful grinding. Additionally, downshifting ALWAYS resulted in grinding. Most of the time I just skipped 2nd gear altogether.

Transmission comes with all the hardware and sensors EXCEPT one (last picture). I don't quite remember which one this is but I needed it on my replacement trans.

Perfect for someone with a blown transmission who is okay with skipping 2nd gear while driving. If you are looking for a nice case and good internals for modification, this is also a good choice. Finally, it could be relatively cheap to bring to a shop for them to replace the 2nd gear synchros (or even all of them), that way you have a worry-free newly rebuilt trans.

These are selling for about $2K on Ebay from salvage yards with unknown histories and no way to guarantee functionality. I'm selling for half that with intimate knowledge of how it drove when installed on the car.

Come take a look and drive away with an almost complete transmission. WILL NOT PART OUT, guaranteed compatible with 2012-2015 Honda Civic Si (2.4L I4) only, can also be made to work with 2006-2011 Civic Si, 2001- 2005 Civic Si, and even the Acura RSX (K20) and TSX (K24).
