    The removal of the clutch shuttle valve (clutch accumulator) is required when installing a twin disc style clutch to gain more travel in the hydraulic system. I run a Competition Clutch Stage 3 dual friction clutch in my 2013 4x4 Tacoma and even with all the play taken out of the clutch pedal i had a difficult time getting it into 1st gear at a stop. This solved the problem. It also made the clutch a little bit easier to depress and gave it better feel.

    Notes:
    -I clamped the fluid hose at the clutch master with clamping pliers to keep the master from draining. Bleeding was super fast too.
    -I accessed the upper shuttle valve bolt through the fender well with a long extension, shallow 12mm socket attached to a universal joint.
    -The fitting to join the two hydraulic lines is metric thread available at a local parts store.

    It's interesting that this is the first time that this has come up. I'll definitely be following this thread.

    Instructions for this mod came with my Competition Stage 3 Clutch but said it was only necessary for twin disc set ups. Clutch engagement feels better and now I can get it into 1st gear every time at a stop. Before I would have to put it in 3rd then 1st almost every time I pulled out.

    Very intuitive. Hmmm. I had to do the same thing with my stock transmission after a while. Makes me wonder how many people with transmission issues could resolve them with this mod?

    Looks like I'll be doing this on the weekend. I haven't pulled it apart yet but there is fluid spewing from my accumulator lol. Why put a new one in when I can just take it out lol

    This is why when it cold out your pedal feels funny in case any one wanted to know it mostly put in for shitty manual trans drivers that have jerky starts ect

    It is easier to just take the back off the valve and remove the valve inside and reassemble. No need for adding a by pass.

    I am not sure what you are asking. I removed the unit from the side of the transmission then removed the back plate then a big snap ring. I could not get the cover off so used compressed air to pop it open. I lost the internals doing this so I do not know what they were. A spring and a valve is my guess.

    I'm saying that it is easier to take the guts out of the shuttle valve there by deleting it, rather than removeing it or buypassing it. No parts to buy
