My 1-2 had broken spring as well. Use 600 grit paper to smooth out any score marks from broken springs . Lots of meat on the o ring and teflon ring. Use #45 torque to hit top and score the check ball bore
Instead of using the ball, I cut the end off of the pins at a length that is the same diameter as the pin. I drove that in and then steaked it the same way as you would the ball. It is exactly the right size, so it won't split the 1-2 housing or swell the valve body.
Is there a reverse accumulator or solenoid somewhere in there that can be changed as well... I'm getting a 2 to 3 second delay when I shift to reverse.
I think I've got the same kit, I realized after installing the 1-2 ball first that the kit doesn't come with enough smaller balls. Need 2 for the forward accumulator. I've since looked it up and there's a version of the chinnax kit that comes with 4 small balls and 2 bigger ones. Make sure you get that one everybody! I swear it said sonnax when I ordered tho.. I measured the small one I had left, it's 0.230 same as the pin so I think they are actually the right size
Easiest way is to just cut the stock pins and not worry with the balls I should have done it that way but didn't think about it tell it was back together
With the 1-2 housing, why did you put it in there like that? I think you could've gotten away with a regular piston because that 1-2 shift is going to be super harsh.
Idk that what the Sonnex instructions say to do and the transmission shifts super soft in my opinion might be different when I turn up the line pressure
