The TSX 6MT swap thread

[evo6011]

How much did that tranny cost? I assume labor was free considering you and your co-workers did it?

[Skippy]

The transmissions go from anywhere between $600-1400 depending on where you buy.  I spent $860 on mine because it had like 60k miles on it and it was local.  The labor was indeed free when I did my swap.  I did it in a day.  Got the old tranny out by lunchtime and had a few friends help me put the new tranny in.

note: there will be a bunch of nuts and bolts missing, so you will be running back and forth between the dealerships and/or auto parts stores.

If you are strapped for cash and you want new parts, you can go to http://www.hondapartsnow.com/ to order the parts. Just take the part #'s listed below and copy and past iit in the "search by part number" at the top left of Hondapartsnow web-site. I have compared their price to a lot of the other Honda parts dealers and their price is usually cheaper than most. If you find a cheaper place, feel free to post it here.
Some of the parts like the clutch, brake pedal, shift console/base, shift linkage can be bought used but the wheel bearing and hubs, passenger side axles will need to be new.

parts list:
5 or 6 speed transmission from a K20 or K24.

either a K20 or K24 clutch kit and flywheel. (cannot mix and match. has to be either K20 clutch and flywheel or K24 clutch and flywheel)

There's already a 5AT to 6MT swap thread Wai. If you want to contribute a parts list, do so instead of opening up a new thread. I'll go ahead and mash the two together.

[rjp6262]

now this being a swap thread for the tsx 6spd, can we swap ratios from other K series transmissions? say take the ratios from the RSX-S or new Civic Si and put them into our trans case?

[Skippy]

There is a discrepancy with the information stated.  K20 transmissions (namely the K20a2 / K20zX RSX-S transmission) will not bolt up to an Accord chassis.  Only TSX and Accord EURO-R transmissions will swap into a 7th generation Accord.

[rjp6262]

well what im trying to figure out is if we could take the internals from the RSX-S trans, and throw them into our trans case in place of the stock gears?

[Skippy]

I was not responding to your question when I stated that information was incorrect, I was replying to wai_pang's information.  He states that any K20 transmission may be used for 6MT swaps, which is incorrect except for one.

You're better off swapping to a Euro-R transmission than trying to see if you can swap internals.  The Euro-R transmixer has the exact same gear ratios as the RSX-S, but in addition also has a shorter final drive AND a limited slip differential..the gears WILL be shorter than an RSX-S, and you will have an LSD without having to go third party.

One member on the old G7A (asnstyle if i'm not mistaken) swapped to a Euro-R transmission.  The chart says that the Euro-R has a K20, but fits in a CL7 chassis which leads me to believe that either the chart is wrong, or Honda designed this K20 transmission with a case that bolts up to the TSX chassis.  If I am correct, this is THE ONLY K20 transmission that will fit an Accord.  I am kicking myself for not finding one of these...If I do...I'm swapping..again.

I believe your assumption is correct Skippy.  As I recall, you taught me that the reason why the TSX tranny will work and the RSX-S and Civic Si tranny will not is because of the mounts.  Since the CM5/CM7/CL7/CL9 all use the same mounts, the assumption would be that even though the CL7 has a K20 motor, the transmission will still fit.  It's a good thing our cars are like legos.

ahhh alright i gotcha. i'll just have to wait and see what all happens with my car. i want to do this but dont know if i will DO it.

[wai_pang2]

That, I did not know or was even considering. is it just the motor mount that don't bolt up to the chassis or is there more that?

[timot_one]

I know that the transmission mount definitely does not line up.  What I'm also unsure of, which may be another issue, is if you need different or custom axles or or midshaft.

[Bobsk24]

I should be doing this in the near future, don't you also have to run a wire from your brake lights to the transmission because of the whole "not throwing the car in reverse when your trying to go to 6th gear"?? Thanks
