Is there any must need to know tranny info when converting a 2000 Civic EX 4-door to a manual from an auto???i can only use a 99-00 ECU I think because of the harness!what about fitment(2-door vs. 4-door)???bodystyles and years etc..

p.s. sorry to start another tranny thread

 

only thing that matters is ecu and engine. car parts are more flexible than you might think.
