Is it possible to put paddle shifters on a 2002 WRX manual tranny?

Yes, it's possible.. people have done it in the past. You could use either a KAPS or Modena sequential gearbox. The gearbox itself will run you about $13,000.. plus you will need a six speed transmission from a STI to put it in, the electronics to run it, and of course the paddles themselves. I would guess you could get it all set up and working for around $20,000, assuming you do most of the work yourself.

But can you choose whether to use the shifter, or the paddles?

I'm sure you could use either, or both. With the proper electronics setup it's just a button push.. doesn't really matter where you put the button.

It won't be cheap, that's for sure.
