I am looking for as much information as possible regarding putting a
manual transmission in a 1998 Honda Accord V6; Forum/message board
postings, articles, etc.   The swaps are done by using an Acura CL or
Acura TL manual 6-speed transmission; (Honda did not sell accords with
6spd trans for that year) Postings talking about 99, 01, and 02 models
are acceptable too, as they are all the same body style/engine/trans
internally.

Thanks

This sounds like a job and a half.
Replacing the Automatic tranmissiion with a Manual one, which means
adding a clutch as well.
Good Luck.

Yep, it'll be a large job.

I've found that the 2003 through current model year Accord, 2004
through current model year Acura TL 6-spd, and the Acura CL's, all use
the same identical 6-speed transmission.

The 2003 accord, which is the seventh generation accord, actually uses
the same engine core as the 98-02's for the V6; it has upgraded
exhaust, intake manifold/headers and so forth to give it the extra
40hp, the engine itself however, is the same. I'm eager to learn if
the ECU/ECM of the 2003 accord would work in a 98-02 accord; that
would make swapping a manual trans in the older accord much easier
than making it work with the existing wiring harnesses.

This is a project that others have completed succesfully in the past,
it is no doubt an expensive and tedius one, but something that gives
bragging rights I suppose, and a boost of personal confidence for
being able to complete such a task. Not many 6-spd V6 accords on the
roads.  Less than two-dozen in the entire country, I'd say.

I have a feeling I'll be answering my own question before a researcher
provides the information I'm looking for.

Which country/state are you in?

Cheers

i am looking to do the same thing also,
there are complications, mostly wiring (speedo,reverse lockout,etc)
v6performance.net has most info i believe. we're pretty diehard on that site,
easier way would be to get the Dr.Evil auto tranny (race built) and
set and forget it! no wiring headaches. although a member is
developing a patch harness that'll hookup to the accord properly.
we'll see soon enough...

the 1998 accord V6 came with a J30A1 v6 engine. what you need to do is
find another '98+ honda or acura car with that same engine but 6 speed
trans in the junkyard. The parts you will need from a donor car
include:

the transmission itself
the ECU from the donor car
the shift linkage and shifter box
the clutch master cylinder and resevoir from the firewall
the pedal assembly with 3 pedals
the piping for the hydraulic system that actuates the clutch
the slave cylinder that actuates the clutch on the manual trans. 

you may also need the axles from the donor car, if the bell housing of
the manual trans is a different shape.

it really shouldnt be too difficult of you have done transmission work
on a car before. you need to take the old trans out, bolt the new one
up, remove the automatic linkage and replace it with the manual
linkage. you need to remove the auto pedal rack and replace it with
the manual pedal rack. you need to attach the clutch master cylinder
by knocking out the factory plates, the the clutch master cylinder
would have gone if it were in your car, and hook it up to your new
pedal assembly. you then need to run a hydraulic line to the slave
cylinder that is attached to the manual trans to actuate the clutch.
you need to hook up the donor car shift linkage and run it to the
interior of the car through the old autmatic hole. this might be the
trickiest part, if the manual shift mechanism doesnt fit into the old
auto hole well. it may require some fab to build. Hasport.com may have
a shift box for the K-series engine that will work with the cable
shift linkage your transmission will most likely have, or you can try
to adapt the one from the donor car if it looks like it will fit.
after that, you need to swap the ecu to prevent the "Auto trans Lockup
solenoid" check engine light that you WILL have if you use the auto
ECU. after that you have to bleed the hydraulic system to ensure that
your hydraulic clutch system is seeing the pressure you need to engage
and disengage a clutch.

no doubt it will be a big job, but if you have about 3 days of
downtime for your car, you should be alright.

there is a place in colorado that would perform this swap for you, called PFI.
you can find them at pfispeed.com. 

as a warning, if this is your daily driver, you may want to find
another one until the project is finished, incase you run into any
hiccups.

the other option would be to trade in your accord for an accord that
already has a 6 speed. good luck!
