Since I've had my car (2020), it's always had a tendency to go from first straight up to reverse when shifting. Especially when cold. I've done all bushings from the firewall back, but I still have to be very careful when shifting from first to second. Shift from first requires a push out of first to let the shifter try to center, then carefully go up to second.
I haven't made any improvements to the shifter at the cabin. Are there similar bushings or a "centering spring" or something under the shifter than can be changed? All the focus seems to be on the firewall back, but I wondered if there is anything to prevent my reverse kiss tendencies at the shifter instead (besides the shiftee - me). Thanks. |

Mark the splined shaft for depth and spline position.
Keep the current depth and rotate one spline either clockwise or CCW. Drive it. Better ? or worse ? if better go one more spline. IF worse go two splines in the opposite direction. You'll know when it is getting better. |

Most of the time, the amount of rotation required to correct a misalignment is only a degree or two. Good thing there are no splines on the ID of the mating piece. |

Your shift adjuster is the shit and I may still pull the trigger on it. I'm having to relearn how to shift this car since it was wrong for so long. It's a significant effort to pull the lever over to drop into first, but that could be the new stiff springs and no longer worn plate and shaft. 2nd/3rd and 4th/5th currently feel a little close together. |
