I feel the need to post after doing much research and one successful auto transmission swap.


I put a 2010 5 speed automatic transmission into my 2008 mazda 3 s. The part #s are different and the engine displacement is different.

06-09 5 speed automatic transmissions are a Mazda part # fsk00 2.3 engine
10-13 5 speed automatic transmissions are a Mazda parts # fsk30 2.5 engine

The later model transmission works fine in my 2008, different axles must be used. no problem fitting and plugging in the wiring. I did use my TCM from 2008. Not sure if the later TCM will cooperate with the earlier year ECM.


The only difference is the transcooler inlet pipe, not a big deal.

I also think a 5 speed auto from a 2.0 2010- 2013 mazda 3 i will work. The Torque converter #s are different, is all I can see.

Mazda part # fsk40 2.0 engine.
Very abundant and inexpensive.

My hope was the improved/ and or beefed up the transmission, plus the are cheaper and easier to find from junk yard/ ebay.

Hope this helps some DIY guys out there zoom zooming, LOL

What cv axles were used also what torque converter? I am doing the swap for a customer currently being that the 2008 5 speed is hard to find in my area

You need axles for a 2010-2013 the inner spline count was changed.

Sorry forgot the torque I used from the 2010 + Not sure if they would interchange.

So I just ended up doing the same fnr5 transmission swap from an 08 but now I’m having the problem of my starter hitting the flex plate??? I cannot figure this one out. I did not remove the flex plate and I’m using the same starter that I took out. Any ideas on how to resolve this???? I have done some research and seen people grind down the starter gear?
