4AT to 6MT conversion
im thinking about saving up and do it. i made a rough list of the parts that would be needed and all summed up the total is around 5700$ in parts.
here's the list:
transmission housing 550
clutch pack 900
clutch release 150
clutch master cylinder 250
clutch housing 450
differential 1200
mainshaft 900
clutch pedal 150
reverse gear shaft 200
shift fork-fork shaft 500
shift lever 300
console 150
is there anything i forgot?
im thinking of doing that instead of the 3.5L conversion... it would be unique, and the car would be much more fun to drive! plus i will get extra WHP cuz the 6MT i think only takes like 15% of the crank HP instead of the 25% the 4AT takes...
it would bring me close to the HP a 3.5L conversion would bring me.. but id get more fun, and a LSD
so what do you guys think? i think it would be a nice project.
oh and NO, i wont sell my TL to buy a CL.

Tell me how it goes!! I want to do that after I get my first pay check. Hopefully I get a job after this quarter to kick it off. Yeah... I only like the 6 speed tranny from CL-S not the CL-S itself.

LOL.... what I think you should have done is just bought a completely stripped out TL, and just added parts. You probably dont have any stock parts left in the car!!!!

That would be the smartest thing. he needs a new ECU no matter what. It gives me a headache just thinking of all the work, but I guess it would be really cool.

buy a rear end cl-s 6 is cheaper, i bought a 2003 tl-s with only 5000 miles wreck back then just for parts, and i took the whole interior to put in my 2002, small stuff that you not aware off adds up, and you can part out the stuff you don't need, often times you can get alot of money back by buying complete wreck cars and part out. plus with 2 cars you can see the difference such as wiring.

why would i need a new ECU ?
and yeah i forgot about the parking brake.. nothing too complicated tho.
if i could find a rear-ended '03 cl-s id buy it.. but ive never seen one in any junk yard, in fact, ive seen only one TL-P.

oh yeah forgot try insurance auction first if you are looking for the whole thing, junk yard owners buys from them, if is in junk yard already someone might already took some stuff, (i love to go to junk yard when i was in high school) or it might sit in the yard too long where the parts is expose to sun and rain. if is in auction the car is ususally fresh....

It won't work and here's why.
Just to get your started you'll need:
engine management computer
transmission
flywheel
complete shifter assembly
clutch package
clutch master
clutch slave
clutch hydraulic lines
pedal assembly
emergency brake assembly and cables
engine mounts
engine shock
subframe
axles and stub axle
intake plumbing
catalyst forward exhaust or Comptech header assembly
center console assembly and related minor components
changes to the wiring harness as needed
new gauge cluster
throttle body
Parts that will need to be CUSTOM fabricated:
clutch pedal mounts
additional engine mount
custom axles
The ECU in your car is completely different than the CL-S 6-speed ECU. Your car has a traction control system, the 6-Speed doesn't. Therefore, who knows how your car will react when the new ECU is installed. Also, the new ECU is programed for the Type-S engine, you do not have this engine.
This project is performed on a Type-S would cost upwards of $10,000. If it were even possible on your car it would cost even more than that. It is about a weeks worth of work for 2 techs to complete the job.

Oh and the ECU swap isn't just like, unplug one, plug in the other. You will need to rewire the entire car. Meaning every wire under the hood, every wire throughout the car that goes to the ECU will need to be removed, reconnected, and then connected to the new harness.

fucking ECU. what will it do if it cannot "find" the transmission? i thought it would do useless work without really controlling anything.. oh and fuck TCS i'll just disable it.
also, why would i need different engine mounts & shocks?? i know the tranny will probably require new mounts but that goes in the installation/labor part.
and why the new gauge cluster?? and the subframe? and i already have a CL-S throttle body.. and everything else in your (mrsteve) list is in mine too.. the clutch parts i listed actually contain many parts i just put them together...
oh and why the new intake plumbing (i already have CAI) and headers? (that i already have) i dont see why i would need to replace those?

Um, if the ECU isn't replaced and is still programmed to shift a 4AT transmission it will throw all sorts of check engine lights. You also may have trouble starting the car because the ECU will sense the transmission isn't in "park."
The 6-speed cars have an additional motor mount. I do not know exactly why but I am sure it is there for a reason. There might be additional strain or vibrations from an manual transmission.
You will need a new subframe because the automatic transmission subframe won't work with a new transmission, they are bolted up differently. Also, no one knows if the CL-S subframe would even bolt up to a '99 TL.
The intake on the 6-Speed is different from the automatics. It bends differently and is different due to the different throttle body. The 6-Speed throttle body doesn't have a traction control module. The headers on the 6-Speed have a slight bend in the rear piece to clear additional hardware with the 6MT transmission.

a 3.5L conversion complete with transmission work (or else it will fail after a few weeks) is around 7k... it would give me around 20whp more than a 6mt..
but i guess that's what i'll have to go for...

id rather have a titanium/kevlar tranny that will provide me peace of mind than have a cheap ass tranny that could fail anytime...
also, 5k seems kinda low...
block paid 250$
heads 1200$
pistons 800$
tl-s cams 330$
tl-s tb paid 150$
v-afc 2 paid 185$
mdx manifold 700$
------------------
3430$
but then you gotta add the labor for the valve job, the port and polish job, the engine swap itself, the shot-pinging (hardening) job for the rods, the balancing job, etc...tuning for the V-AFC to go with the cams then if you really want something solid add the transmission work.. around 1500-2000....
that's more than 5k...

fsttyms1 (Kris) should really post in this thread. When his 3rd tranny failed and honda turned their back on him because of the mileage on his TL, he diligently looked into doing the 6sp conversion on his TL. After extensive research, and a lot of time spent, he concluded that it would be sooooo difficult to do, it wasn't worth it.
In the end, he replaced his tranny by himself ....He settled for the 5sp tranny again, because apparently there is a guy on the V6 forums with an accord that has been converted in a 6 speed manual, and the guy owning/operating the car has had nothing but problems with compatibility of the ECU and the entire car.
Overall, it would be really nice to have 6 speed, but you'd be better off buying a CL-S, or a 2004-2005 TL with 6 speed. I know you said not to suggest it, but I think that would be your only option...

I think the 5k figure is probably an estimate most of us gathered when doing a 3.5L swap on a Type S. So you wouldn't need to swap out the cams and throttle body, also I believe at one point DeansBlackCLS was selling a kit for the 3.5L upgrade and it came in around $5k installed.

Unless you got a trust fund put your money to better use then trying to put in a 6 mt. Shit get a different car if you want that. Do a sick ass exterior or interior mod, like put Maybach Tv's in the back and use the rest on prostitutes or crack.

lol, prostitutes or crack
i just wanted something different and fun, but now that i see how much it will cost.. i'll go back to the 3.5L conversion
anyone got a link to that site who has kits for sale? i saw it once but i dont have the adress...

Dunno if anyone has ever done a 3.5L conversion on a TL-P before though.

i dont see why a 3.5 conversion couldnt be done on a TL-P ?? i am NOT replacing the intake manifold with a type-s one, which has double stage butterfly intake or something like that... that's pretty much the only difference between the 2 engines.. the mdx manifold is single stage... the ECU difference between the tl-p and tl-s resides in that single vs double stage intake... there's nothing else...
oh and even on a TL-S a well done conversion will cost more than 5k !

The MDX manifolds I've seen are all dual stage. (I've seen 2 different ones) They are also pretty big so I don't know if it would even work on a TL without a bulge in the hood. Also, why is everyone so off on making the dual stage ones (from a type s) work? You just need an rpm switch and a few wires.

i checked into the 6 speed swap, and the best and easiest way to do it is if you can find a cl-s 6 speed in the salvage yard with rear damage where you can scavange from the front clip, wiring and ecu. it isnt going to be cheap unless you can do most the work your self. then you are going to run into problems that will take time to sort out (computer/electrical) there is some one on AV6 that did the swap.
Very Tricky, and very expensive if you arent doing the work. i came up with about 5k in parts, but, and a Big but, id be doing all the work. like mrsteve said it would be upwards of 10k if you had someone do it.
im still thinking about trying it though

hmmm i thought they were single stage
oh well like u said it cant be that complicated to make it work!!

There is alot more to the ECU than just the intake manifold runner control. You actually seem quite clueless here. The Type-S ECU has controls for the VSA system which needs inputs from many sensors that your car doesn't have. Also, it is programmed for a higher rev limiter, a 5-speed transmission, different cams, etc., etc......
Save yourself ALOT of money and just buy a Type-S.

clueless, not at all.. i already knew everything u said.. but what i meant is there is not anything else that the TL-S ECU controls that could go with the intake manifold change or that has to do with the 3.5 conv... im not dumb, i know the TL-S has VSA instead of TCS, 5sp vs 4sp, higher rev, diff cams, diff compression, etc
i have a CL-S throttle body and it works perfectly with my TCS, the VSA has absolutly nothing to do when talking about a 3.5L conversion. neither do the rev limiter, the 5sp tranny and well the cams are taken care of by the v-afc...
