I know this is probably a crazy question, but has anyone considered doing an smg or dsg tranny swap. Would it be possible, obviously expensive, but curious. Thanks!

How MUCH did the conversion Cost
Less than $2000 using used parts.

First portion will be interior swap, and e-brake relocation.
Good Luck!! It is IMPOSSIBLE to install 6MT interior into a 5AT without removing the transmission.

damn it no damn wiring Details here either lol

03-04, If you get the engine harness and ECU it is a complete BOLT-ON!... as far as wiring goes.

^How does that wore with the doggy door Type 1 ECU?

What is the build date for the vehicle you swapped? I'd love to do this, but I'm afraid I'd run into some sort of transmission problem since I have the Maxima-style ECU. I fear that a direct swap for a 6MT manual ECU might be impossible.

Does anyone know if any of the 6MT ECUs were Type-1? When did they first start building 6MTs, and is that within the early ECU range?

I'm thinking about rebuilding my auto tranny, but swapping to a 6MT would be a lot of fun.

I have done this, parts list looks good - don't really need the gauge cluster if you don't mind AT CHECK and the lit up gear indicator.

Save yourself time and grab the harness and ecu from the manual car, then the only wiring that needs to be done is 12v to the starter relay on a switch, or you could wire it to the clutch pedal switch instead for a factory feel.

You would have no idea my car was ever automatic... feels completely stock.

Oh and grab the manual e brake cable too - you disconnect it from where it splits off to the two rear wheels under the car. The auto one is way too long to use since it runs to the pedal instead of the center console. Its like 25$

Is the 03 sedan 5at ecu the same "type 1" as the 6mt? If they are, i'm guessing they work.

Since there isn't any wiring for the clutch pedal switch. You must wire 12v switched directly to the starter relay. That way all you have to do is move the key to "START". That will activate the starter. If you put a switch in between the 12v bypass, it will act as a kill switch. Think about having a manual car.. You cant start it without activating the switch.

i have all the mechanical parts gathered for my swap so far other than clutch line piping and some miscellaneous hardware. i really wanna jump into this project as soon as possible. do you think its reasonable to start tearing her apart without having yet gotten a 6mt wiring harness or ecu? what is the best way to have the car convinced its in P/N? and for the record i do plan on getting a 6mt ecu and harness but would like to get the car running without if possible.

Sorry for the late reply. The 6MT harness and ECU are not needed for the car to run or drive.You will get codes. You will just need to wire up the Neutral Position Switch. That will involve splicing into your existing EFI harness. Not really a bit deal. You will not have reverse lights until you wire them in or make a closed loop switch.
