    M/T Clutch regulator valve mod

    Anyone with a manual trans please stay tuned for a great mod!!!

    If you are at all familiar with Kia and there M/T, the one thing they are known for is that shitty clutch feel. If you are familiar with past forte platforms this mod was much easier. But with a change in transmissions parts and and updated slave cylinder that is now internally mounted and part of the throw out bearing. This has become to be more of a challenge. But with direct access to Kia parts I have found a quick, clean way to get away from that spungy clutch we all hate so much.

    I will post my findings as soon as installation is complete.

    Update on the mod!
    Just finished up installing the updated line. Took her out for a spin and she is a totally different animal!
    Clutch feel has improved greatly. No more messing with the clutch to pull out smoothly with no bucking or over slipping the clutch.
    Also 1st to 2nd is a lot smoother
    It become more involved then I wanted it to. I was looking for this to be completely bolt on but I ended up having to take off my hardline off and reflare it. Reason being the flare on the hose I ordered from Kia (from a different year vehicle) was a male bubble flare. And the line coming into the regulator that I replaced was also a male bubble flare.
    My first idea was to find an adapter that had two female bubbles flares in it. But nothing like that exists.
    There for I had to cut and make a normal flare. Which then would bolt to the adapter that was in the new rubber hose.

    That is the easiest I can explain it. But either way here is a picture of the old regulator and then the new rubber hose I put inline where the regulator used to go. The only way to fit it was to wrap it into a circle and secure it. Making sure there is no bends or kinks to distrust the flow

    Old


    New



    This line is literally the only piece you can use without extreme modification or fabrication. Reason being one side is a normal brake fitting. But the other going towards the clutch master cylinder is a snap fitting with a c clip.

    Here is a pic side by side
    Notice the new brake hose and the different ends


    So this is my thought
    First I would like to get some feedback on this to see what everybody thinks
    (Mostly concerning m/t owners)
    If I can get enough people together who would be interested in this mod.
    I will put together these kits to that when u receive them. It Will strictly be a bolt on procedure. There will be no need to cut any of your exsisiting line, or any flaring involved. I know there are owners that probably know how to flare a line, but there are Also most likely more than that don't know or don't have to tools to do so.
    The list will include the hard brake line that goes from the clutch master cylinder to the slave cylinder.(modified with a new flare)
    The brake hose that is used to replace the regulator assembly
    And one adaptor
    I will also make a full D.I.Y to go along with this so the process it cut and dry
    Full installation time including bleeding the system is about .5 -1 hour for an experienced person
    And possibly 1.5 hours or longer for a first timer
    I am not quite sure at how much each kit will cost. I will have to put it all together and do some math.
    But I can say it is a relatively cheap mod


    Please everyone include your feedback.!!

    What does it do?
    Eliminates the regulator giving you better clutch feel and no more sloppy shifts.

    The regulator works against you. It limits the fluid to and from the slave cylinder. In return you get a really shitty. Half assed delayed. clutch response. There for your driving experience is sub par.
    This is a very popular mod from older forte models. But in those applications the slave cylinder was external. The delay valve was easily accessed and part of the slave.
    As I explained in my post our vehicles have an internal slave cylinder. There for they put our valve inlone, making it more difficult to delete.

    My professional opinion. This valve is actually the part at fault for most of the premature clutches I see failing on most forte/soul and rio platforms. Very bad engineering on there part. With the valve there for protection, but it's actually working against you. Regualting the pressure to and from the slave, slowing down fluid flow. Think about it. When u release the clutch to engage a gear, the valve is slowing down that release.There for extending the pressure on the clutch. So That split second of extended pressure on the clutch time and time again creates unneeded wear and tear.
    The valve also creates less "shock" on the clutch. Stainless clutch feel. They overly focus on these types of thing and over engineer certain parts. In return we get a shitty driving experience.

    Oh okay , thanks for the explanation. Never heard of a regulator on a clutch line before. Is this a kia thing or do other manufacturers do this? I'd be interested down the road depending on price and it being direct bolt on. To be honest the last few cars I've driven have been 14+ years old with over 200k kms on them so the Forte is a big improvement. I do notice the clutch feel could use some improvement but it's a lot better than I have been used too.
