So I just bought a 00 civic ex auto and I want to do a manual tranny swap. I have another car that's got a blown motor but clean manual tranny. Are there any complications with the swap? I have all the parts except gaskets

 

Google search that question and add "honda tech" to the end of it. You will find your answer there as this topic has been beat to death, revived, taken on a vacation where it was kidnapped, held for randsom, killed again, vicerated, then they hung each piece of that exact question at every corner of honda-tech territory. Thats how many times this question has been asked.

 

This is a good answer
