Omega General Help / Automatic gearbox misbehaving
« on: 29 September 2020, 15:32:15 »
On my Winter Omega that I'm about to take out now on October 1st I did an oil change in the Auto gearbox.
Oil didn't look bad and smelled as good as it can. Changed the filter too.
Now when I drive the car it behaves strangely. When standing still and I start the gear box free wheeling a few seconds and then hook up. In worst cases with a big tugg and muffled clonk sound. It didn't do this before the oil change. Oil level is OK.
I have used Valvoline ATF Dexron III.
I haven't driven it for a long run yet, just a few laps around the block. Engine is up to temperature. When it starts running it shifts OK and kick-down works.
If I put it in 1st gear it works as expected. The free wheeling is only in Drive.
What could have happened???
Thanks
