At the end of the video you briefly touched on reinstalling the speed sensor. But at 4:00 where you magically cut to having the case split, you never mentioned that if you don't remove it now, you'll break it off when you pull the case apart.
I just got my element back with this mod done. The Element ALWAYS needed a 6th gear on the highway. My RPM's dropped 800 with that extra gear at highway speeds. It wasnt cheap but the fuel savings should be worth the expense.
Did you have a shop do it? What kind of cost was it? Been looking at getting one of these little cars but I see a lot of people complaining about the 5 speed ratios
@thesuperderp1379 Yes I paid a shop recently when my transmission died. I paid too much 995.00 for the 6th gear mod parts only new clutch, synchros, new cv azles. Total cost 3700.00. The value of the car isn't much more. Honda went on the cheap and left 6th gear out. This mod doesnt give you a reverse lockout, so you have to be careful. It is easier to shift from 4th to sixth than 5th to sixth with this mod.
@paolosheaffer9540 Terry's auto clinic in Milledgeville. This was his first conversion, but he specializes in manual transmissions. Now, he broke my speed sensor and charged me for it. You have to remove it before pulling the cases apart. The problem with the mod is you dont have a reverse lockout and sixth is right next to reverse. I find it easier to shift from 4th to sixth instead of fifth to sixth as you avoid accidentally hitting reverse. My element is the AWD version. The Honda element owners forum online has a list of the patrs you need. I had a full transmission rebuild with new synchros , clutch, cv axles and this mod 3700 bucks. 995 he charged for the mod parts included in that 3700.
In theory can't u just swap over half of a tsx casing with the tsx gears for instance onto the crv or element main half of the transmission since everything's the same and the only difference being is u would need to use a tsx shifter that way u get the shifter lock out and the speed sensor stays the same plus u get half of a light weight magnesium case
My honda fit could use this. The latest honda fits have 6 speed manual but the final drive ratio is the same. Like you said, 4200 when going 85. Kills the gas mileage. Automatic is rated better for highway miles because of this.
Just awesome! Any updates from the owner? What kind of mileage difference is he seeing? Looking for someone in the NYC/north Jersey area who can do this.
Did you end up using part 5-6 Synchronizer Sleeve Set 23626-PNS-315? I'm considering this for my Ep3, and the part is $500 alone. I wasn't clear if that one part is actually necessary
Is this process the same for the ep3 trans? I’m going turbo with my car, but I’ve been told my 5 speed gear ratios will be better for boost. I’d like to add 6th as a gas saver gear so that way I can keep my 5 speed gear ratios for the turbo.
Fantastic vid! Thanks for posting! What is the tallest gear you can drop into the sixth slot? Looking for highest efficiency/lowest RPM at 80 mph on flat ground at sea level. I need zero acceleration in sixth, just enough to keep it moving. Greetings from NYC!
That is a cool upgrade for an Element that so badly needs a sixth gear to keep highway revs down and saves some gas. What is the long term durability of this? Did the transmission fail after only 10,000 miles?
@@jonpfun The Element has a much larger frontal area than any coupe or sedan the K24 would be installed in. Means more drag at highway speeds and therefore greater load on the gear stack and higher temperature if not lubricated effectively. In any case my concern was also based on anecdotal information. The Element was not an entry-level SUV so Honda designers could have included taller gearing if they thought it would be durable.
Also no VTEC engaged in the element means a LOT quieter highway mileage. The damn low VTEC engagement means the 5spd is droning at like 65 mph on the highway. It’s so F’ing obnoxious.
always follow shop manual instructions.. after installing a different gear to the mix, thrust clearances and torque values should be checked...or you could be setting yourself up for failure
Found this video because aim trying to do something similar with a Mazda trans lol. Even expecting the same rev lockout issue because the donor 6 speed uses a lockout in the cabin side of the cable shifter setup and I will likely have to use my original rod shifter setup. Lucky for me 6th is opposite of this trans and is next to 1st. So no real issue with hitting it at speed.
I didn't know you were in SC as well. It'd be cool to have you do some work on my (former) nationals C-Street S2000 or do this swap on my Element once I finish the K24A2 swap.
Awesome video!! Looks like I may do this mod to my element transmission..... I also have a question.... I have a k swapped integra that used to have a fwd 5 speed and I just put a awd element transmission in it..... I am having issues converting my car to countershaft speed sensor, its wired correctly and my hondata wont read it and we did change hondata to rear countshaft speed sensor.... what can I do???
I just finished doing this on my 2006 CR-V. As Mark said the fact that Honda did not do this from the factrory is a conspiracy level WTF. Huge thumbs down for Honda. A few notes about the 2002-2006 CR-V process is the gear selector from the donor TSX will NOT drop into your CR-V. The mounting holes do not line up. However there is hope as the CR-V gear selector piece has a blank mold of where the solenoid "should" go. With the proper drilling and measurements I think the reverse lock out could be transferred over to the CR-V. Wiring would be simple - run a 12V lead to the solenoid, and install a "normally closed" push button on your shifter. The lockout is not necessary, but it would remove the stress of shifting into 6th. The shift from 5th into 6th without the lockout is a problem. I end up going back into 4th because the shifter mechanism likes to return to center when it leaves 5th, which screws up my alignment with 6th. With some practice this is not a problem, and yes I did buzz reverse trying to go from 4th into 6th after missing 6th, and I've been driving/racing stick for 22 years. I would very much like the lock out. All that aside this is an amazing mod for Elements and CR-Vs. I used a 2007 TSX 6 Speed ($350 on Craigslist) for this project. Mark thank you for posting these videos. Checkout Harbor freight and get a hydraulic press, and some snap ring pliers using online discount coupons. It'll run you about $150, and save you a lot of hammering, and gnashing of teeth.
Also if the VSS touch the gear, I believe 3rd gear, it will ground out the car. At least in the 05/06 DC5 as I was plague with it for the first 3 mins hahah
So literally all I've gotta do being I've got a complete 6 speed Rsx transmission and a 5 speed awd transmission is drop my gear stacks from the Rsx 6 speed and final drive into the 5 speed awd transmission with zero problems? Literally drops right in?
no need to make a full video about that. hondata is a company that makes a chipping kit for a stock honda ecu. they come in 2 types. the s300, for b, d, h and accord/prelude f series engines. kpro is used for k series engines and can be retrofitted to s2000s. both types are used to tune the ecu in the same manner. plug in a laptop and tune away
I just did this conversion along with a new clutch. All the gears work fine. Except 6th gear. It will go in no problem. But as soon as you press the gas, it pops out. Can you help?
dear kind sir....I want to do this to my Chinese 250cc it will be port and polished and bore to around 300 or past...76x65 so my question to you is...can we find parts such as yours for motocycles if so were should one search im seeing this is car parts..
Hello there I don't know if you will see this. but do you know if you can use the element shifter in a different honda vehicle. I like how it points upward to mount on the center consol. the trans itself is already a 6 speed but I didn't know what modifications I would have to do with the shifter itself thats on the center consol. ok thanks!
my 06 accord 5 speed hit 3100 rpm at 80mph , and my buddy 06 tsx 6 speed hit 3500 rpm at 80mph. the accord and element from those year have almost same engine right? and probably the same trans too right?
My brake fluid cap is fine, Mark. Unless you broke it... Did you break it? You broke it didn't you? Didn't you?! Damnit Mark, why did you break it? It's not broken, at all, not even a little.
Hey Y'all. Are you still doing this work? I am interested in adding a 6th gear and will be driving down to FLA in March. Let me know if you might be able to fit me in and what the costs would be. Thanks!
oh man I wish I had the skills to do this, I know my way around a car...but tools, shop and buddies to help me? i dont have that....my E is also only front wheel drive too, guess I should just replace the call all together haha
Hello, will the installation of a 6th gear work on a 2004 Honda Element LX automatic? If so, is there any additional parts that I would need? Thanks in advance.
More than what its worth. done youself around 4k with all parts Its much cheaper if you do it yourself obviously. or you will be out more than 10k for labor plus 4k in parts
Im assuming thats a pci side skirt kit? What front lip is that on the EJ1? btw it'd be cool to meet up sometime, i also live in the South and our cars would be good competition for some friendly road racing. My EJ1 is N/A H22A but ugly as shit compared to yours.
Measure the thickness of the gears and collars you are removing and compare them to the ones you are putting in, adjusting shim thickness on main and counter shafts as needed. It's a major red flag for your countershaft to engage the snap ring like in this video when putting the top half of case back on. The snap ring should sit just out of the groove in the top countershaft bearing when the case is put back on, flipping the trans to let the shaft drop and engage the snap ring on final assembly. This is so the countershaft 'floats' between the top and bottom counter shaft bearings. In this video the shaft shim is too thick and the bearings are being compressed between top and bottom case.

Justin Edwards what are you doing with your time that you only watch hypocrites on TH-cam?
Don't forget to pull that speed sensor because it will get stuck on the main shaft when you separate the case.
How are you does a civic si or tsx 6speed tranny bolt straight onto the element

With manual transmissions the ecu has nothing to do with it. Only an issue with automatics.
the syncro sleeve theres 2 styles one style has a rib for 6th the other wont hold in gear sone 5 speeds dont support it so u need the syncro sleeve to

because you cannot reuse the sychro in the trans you have to get the proper one. they give shit advice.
