Default Vibration/Shaking before shift at WOT
When going WOT or close to it, right before the shift the car vibrates and then is fine after the shift. Is this the PCM pulling timing?

Thanks!

I think if the car gets near redline, it will tend to shake before a shift. That happened to me before the tranny was replaced...you got tranny fluid?
