new to the civic community. I have a 2004 EX and its the first import that I have purchased. I recently took a road trip to ATL from Va. Beach and i only got 28mpg...def not what i was expecting. I was driving 80mph at 4000 rpm. I def need a 6th gear. Would this transmission fit the ex motor with a mounting plate or something? Or would the gears from a 2006 fit my tranny? my wife has a 2006 lx and it gets almost 10mpg more.

It will fit your Civic if you swap in the K20 engine to match it. That's the only way you're getting 6 gears in a 7th gen chassis.

yeah cross matching tranies dosent usaly work plus i think the k20 trani is facing a different direction so it would be backwards or something

wont work... aldo you mpg was prolly crap due to maintanece probs. how are ur sparks? 02 sensors? Tire pressure? how much weight in the car? any mods to your vehicle? also 80mpg is def not a good cruising speed for high mpg. Also are your XXk mile checkups up to date??

i have a 01 ex auto, and i make a 80mile drive almost 2 times a month. and even with 4 gears i pull about 33+ mpg crusing along at 70.

There is a big difference between fuel consumption at 70 and that at 80 too.

Absolutely, try driving closer to the speed limit, thats where cars are designed to get the best mpg. You dont need another gear, these cars get great mpg when everything is maintained and used properly. I could get about 34-36mpg hwy when my car was stock if I kept it at 68-70 mph.

With the ems, turbo and no exhaust I got 37mpg cruising at 70mph without a fuss. That was cool.

i have some mods done and i get 47 mpg so the tranny will not help ur situation

with my a2 swap and all the mods done to it, i still get 32mpg cruising at 70mph on the freeway.
