Swapping AT to MT
Ok Im swapping my ef civic dx. It as an automatic tranny in it. What shift linkage do i need to use or does it matter since i have to cut the hole and mount it anyways? and what else do i need besides the pedal assembley?

Re: Swapping AT to MT
this has been covered many times
use the search button
Pm5/6 ECU ( sepending if staying dpfi or mpfi )
88-91 SOHC manual transmission
pedal assembly of 88-91 civic/crx/sedan
linkage off 88-91 civic/crx/sedan
rear/passenger side shock tower motor mount bracket off 88-91 civic/crx/sedan (m/t)
clutch cable off 88-91 civic/crx/sedan
flywheel/clutch for 88-91 civic/crx/sedan
you will also need the flywheel/clutch bolts
Flywheel- 12point 17mm bolts
clutch- 12pt 10mm bolts
( You NEED the 12pt sockets to get these off, no ther sockets will fit,if you try you will strip them first try )
these are just parts you need. you will also need to do some wiring.
you will also have to plug the transmission hoses coming from the radiator
( idk if you NEED to, but better safe than sorry )

This thread was beneficial for me. B series will be slightly different, of course. http://www.gassavers.org/showthread.php?t=1033

and either jump the black and white starter signal wire plug at the range switch or solder the wires together to make a connection to the starter.
just to clarify, theres a 2 pin plug on the auto shifter assy, take that plug, it will have 2 wires, both are black with a white stripe, these wires need to make a connection so the starter will recieve its signal when starting.

The only way it would bolt up is with a d to b plate. But it's not worth it. And it can be done. Search bar is there for a reason.
