Hi all

My tranny revs up for about 4500 rpm before shifting. It all happens in the morning. Temp outside about 10-12 degrees celcius.

When passing my driveway and entering the road i slowly increasing my speed. I notice some pretty high revs here. It will shift from 1 to 2 about 4000-4500 RPM.

when thats done the problem dont occour until engine again is cooled down.

I know then from reading various post in this forum that high RPM are common when engine is cold.

But is my RPM showing to high? How should i aproach this?

Would it help changing tranny filter and so on? - tranny oil replaced 1 month ago, but not the filter.

Check the correct tranny fluid level. If that only happens when it is cold = tranny fluid cold, then I assume that the refill was not done correctly = not at the correct temperature. = not enough fluid. When it get's warmer, it expands = tranny works (almost) normal.
