Ive got a 2003 Civic si K20a3 5 speed transmission for sale.Its in perfect condition with no grinds.It doesnt come with the shift linkage cables,but I can include a type S shifter and box.This transmission has a 4.7 final drive,so would be a perfect upgrade for a base rsx transmission.It bolts straight up to any other K series engine..ive got it bolted up to a type S engine right now.
Asking $700 obo plus shipping.
