Dirty_SL8

Hey guys. I have had my mind on a 03+ accord 4 cyl. for a while but do not like the sluggish 5 speed. My question is....... will a 6 speed rsx or civic si trans work on any of these years? If so, is there a certain year(s) that is needed? Also would there be anything special that needs done??

I have done some searching and havent found anyone who has done this. It just seems that is would make since that the 6 speed would just take place of the stock, with minimal to no issues.

Thank you

anythings possible, depends how deep your pockets are........but most likely no, i think the mounts are different, not too sure

They are deep enough, but this would be a DD. Dont know if I would wanna drop tons of dough in a DD.

If ur looking into a 6speed tranny ur best bet will be the acurs tsx 6 speed tranny,since they share the same engine with the 03-07 accord, with a bit of adjustments , but it has been done and can be done ...g/l

keep us posted on this.. i wanna know if it fits. i wanna do this to my 06 coupe

only adjustment with the tsx tranny is the adjustment for the speedometer reading, it will be off. rsx tranny will not fit.

Does anyone know if the 6 speed tyranny from the 09 TSX K24Z3 will mate up with the 08+ accord K24Z3's?

if it's the exact same engine there shouldn't be any reason why not

Well for one he doesn't have an 09 accord it's an O3. Do you have a k24engine? I think you do, the TSX will swap no mod necc. The hasport CD5 swap states a 03-05 accord 5 speed will work or an 04-06 6 speed TSX trans will work. Interchangeably

That's great to hear.

A late model Accord Coupe with a mild K Motor build and a TSX six speed...that sounds like a very nice daily driver.

Yeah more power to distribute. Longer gears sorry edit

your answer is yes.

I have a 2003 Accord EXL 5spd from factory.


05 TSX 6Spd
Ebay 8lb Flywheel
Exedy Stg1 Clutch (NOT just an oem replacement)

I did the swap at about 65k . I have 110k now. ZERO issues. LOTS of fun. Night and day difference. When I had all my bolt ons Id be dead even with new Si's and all bolt on GSR integras .

The only challenge is finding the transmission.
Only other thing is that there will be no reverse lockout, which isnt much of a problem once you get used to driving, Ive only accidentally hit the shifter near reverse while driving and it only made a tiny *scratch* and I quickly went into 6th.
Your speedometer will be off as well. I learned to just compensate in my head. Your wheel/tire combo will affect this as well due to the overall diameter of the wheels/tires . To go about 70, I go 84 on the speedometer.

There are fixes to both of these issues but of course $$ is involved and I just learned to live with it :p

did you have to change the cables or shifter on accord to the tsx ones?
