02 Civic 5 spd to 6 spd manual trans swap??
 

Hi all,
I recently bought an 02 Civic EX Coupe with a 5 speed manual. It has started kicking out of 2nd gear at times when I'm keeping a constant low speed and not shifting in 2nd gear. I've read that these trannies are crap and would like to replace it soon. I also have found that my car tachs up to about 3700 rpms at 80 mph on the highway which is much higher than I'm comfortable with. Are there any "fairly simple" 6 spd manual swaps out there? If so, which transmission could I use and what additional parts or kits would I need to use with them? Thanks in advance!

A 6 speed swap is not possible.

unless you k-swap.. but a 6-speed d17? no so much

Pardon my ignorance, but why not? Can I have the 25cent explanation as well, as I am a transmission idiot.

Re: 02 Civic 5 spd to 6 spd manual trans swap??
 

because there is no 6-spd D-series transmission to bolt it in. K-series have different mounting.

Are there no adapter plates or kits that could be used to install a 6 speed trans from a similar make, such as an Acura TSX?

Re: 02 Civic 5 spd to 6 spd manual trans swap??
 

None. The d series is considered to be too low powered to need a 6 speed.

BTW: I drive at 75mph (3400rpm) all the time with no problem.

On top of that there is no benefits to having a 6 speed in a civic. Maybe a small bit of savings in gas, but even thats probably small to nothing.

Good point. My 2001 EX (VTEC) will still get 33mpg (with the A/C on) at 75mph (3400rpm) all day long. Not gonna get much better than that.

The only thing I could think to suggest would be swapping in an HX transmission or rebuilding with HX gears. Although the result wouldn't be a completely separate overdrive gear, you would have slightly more fuel efficient gear ratios.

A TSX (or any K-series) transmission could not really be made to work paired to a D-series engine or in a D-native car because the position of the engine and engine itself are to radically different. There would be a number of parts aside from just an adapter plate needed, the venture would not be practical..

People do swap from 5 to 6 speed in k-native cars all the time, but we don't have that option unfortunately. Excuse to k-swap I guess ;)

i guess at this point we should spill out that the K-series, wich is the engine that have the 6-spd, have the exhaust on the back side towards the firewall, and even iof he did use a mating flange work out, he would have one speed forward abnd 6-speed to back-up... JK-series turn the other way the way they were designed compared to D-series.

lol @ 1 speed fwd, 6 speed backup :D

Re: 02 Civic 5 spd to 6 spd manual trans swap??
 

Thanks for all the input guys! Guess I'll just deal with the high RPMs on the highway for now. It's my daily...and only...driver and I'll be driving on I-4 30 mins to and from work for awhile. As for the K swap...how difficult is it and what kind of gas mileage can I expect to get if I were to do it?

Re: 02 Civic 5 spd to 6 spd manual trans swap??
 

There was a bit of sarcasm in a k-swap suggestion.

It's not difficult, but expensive. You'd essentially be paying $5000-8000 to get less gas mileage.
