    SEVERE binding on 2-1 downshift after full manual VB mod

    wheels try to lock up during 2-1 downshift at any speed, used the superior kit and followed those instructions plus locked shuttle valve, plugged accumulator holes in case and did the valvebody bleed mod as well.
    1-2 upshift seems fine, no binding there at all, but 2-1 is pretty bad, car tries to screetch to a stop.
    thats the only issue, how do i go about correcting this? i dont care about engine braking at all so if that goes away as part of the fix thats fine by me.

    There is supposed to be no engine breaking really in 1st. Its just supposed to overrun, like coasting on a 10spd bike.
    I thought that was in the valve body. All of the manual valvebody cars i have do exactly as i mentioned.

    did you do your own valvebodies?
    if so what all did you do to them?

    I'm afraid i am of no help.
    I had Cliff Ramsdell do my trans builds. Although, Brian recently had to refresh the one in Mini. They both had the manual valve bodies installed by Cliff.
    I don't know if it makes a difference but mine are both reverse pattern manual valve bodies.
