So the '08 Kia Rondo 2.4 I've been driving has an annoying shift flare between 2nd and 3rd but only when it's cold. After the drivetrain is warmed up there is no more shift flare evident to me. To avoid this, when the vehicle is cold I'll let it idle 2 to 3 minutes to get some heat into it then drive off. This usually eliminates the issue for as long as I'm driving. The vehicle has 250000 kms on it and the transmission fluid was changed roughly 1.5 years ago and maybe had 6000-7000 km put on it since then. I was thinking about draining off some transmission fluid and putting some Lubegard Red or Platinum into it to see if it would help the issue. Would it have any effect or am I going to need to learn to live with it?
