My goal is to explore the gearing possibilities of the 07-08 Honda Fit Manual gear box using the gears from the 03-05 Civic Hybrid manual. From some online research and help from some internet friends Ive decided to buy both trans missions and document the process and see if everyones questions can be answered. I have a lifetime of experience building cars to different degrees but this will be the first time Ive ever cracked open a Honda Transmission. This not a ‘how to’ post rather a ‘me figuring it out’ post so please chime in with any help.
So far it appears the difference in the case is just the bell housing and the gear sets appear to be the same with the exception of some syncro differences
My goals are mixed with ECO and high powered performance and will be looking for 200HP at the wheels but would also like to get some damn good freeway MPG’s as well. This thread however is not about my car or my goal but about the transmission itself so I will try and keep on the subject of it and cars in general, link to my car is here (it needs updating to reflect this project as it was an A/T before)

My first question I need to answer is what special tools will I need, I do have the factory Fit manual but won’t buy Honda specific tools if I don’t need to.
The following graphs show all info @ 3000RPM or @70 MPH
