    1st, make sure your motor is tuned right. If the motor doesn't spin fast enough, the trans wont shift even if it is set right.

    But if the trans does need adjustment, there should be a small hole in the case....in that hole is a small hex set screw. I cant recall which direction, but turning it one way or the other adjusts the speed at which the trans should shift. Caution....make SMALL adjustments.

    Ok. My engine is tuned the best ive ever had it lol. I suck at tuning im always too rich.
    My car will go down the street screaming at high rpm but refuses to shift, when i went out to tine the tranny i relized i forgot my hex driver so that was a bust. Ill try tomorrow though.
    How small should adjustments be? Like haalf turns or 8th like when tuning the hsn/lsn.?

    try 1/4 turns.
    I will admit I have only tuned 2 speed trans a couple of times...but it is just 1 screw. Like engine tuning, patience is key. don't rush it and try to make big adjustments.

    Ok. I saw 2 screws on my old trans and got scared lol but after looking more one screw is just to hold it in place i guess and the other moved out this little piece of metal that caught on a gear to make it spin.
    I would guess turming it clockwise would make it shift sooner? Ill try tomorrow and try not to mess it up ha.
    Patience isnt a virtue i carry often.

    Zach, your right, there are two. One is straight in, the other is angled. You want the angled one. Turn in to raise the shift speed, and out to lower. Do this in about 1 hour turns (as if the screw was a clock). The smaller the adjustment, the more likely you are to hit the sweet spot. You want it to shift just before max rpms as it will lug if it shifts too low.

    I wouldn't worry about your tuning, as long as your lean enough to get up to speed and everything is shifting proper. you're liable to be better off Rich than lean.

    Zack, make sure there are no loose drive cups or other factors. The 2-speed when set up right will not shift if the tune is way off or if there are problems getting the tranny spun all the way up. Also, if you have dirt in the transmission or a ton of grease, clean it up. Because it works off of centrifugal force, it has to get to speed or no shifting will happen. If you tear into the tranny, make sure the shift pawl swings freely and that there isn't anything binding. This is one of the aggravating parts of this hobby. Stick with it, you'll find the issue.
