With all the excellent info available on this Forum on building a C4 maybe someone can help me out.My Morris early ('67)C4 has a false "neutral" on the 1-2 shift while racing. I leave in 1st and shift to 2nd @6000RPM and it goes into this false neutral and the motor revs to the moon because of no rev limiter.When I let off the gas and it slows down,2nd gear comes back and I can manually shift to high.It shifts manually 1-2-3 in the burnout box and when driving slow. In drive when driven slow it shifts 1-2-3. I tried leaving it in Drive at the track and it took off good in 1st and then instead of shifting to 2nd it hit this false neutral again so I let off and it went into 2nd and then 3rd.Instead of calling it a day I tried racing it by starting in 2nd and it acts like it starts in 2nd,momentarily goes into first,back to second and then can be manually shifted into third.The trans has a Transgo shift kit and H servo.I have put in a new shift cable and cleaned the manual valve in the valve body along with a new detent plunger and spring.Nothing seems to fix it.The problem has progressively gotten worse over the last few times out at the track.Sorry for the long post,but I 'm trying to give enough info for someone to help me out. Thanks.
