Omega General Help / Re: Auto gearbox won't shift up to 4th
« on: 21 February 2021, 13:34:42 »My 2.6 occassionally does this, but no flashing lights it just sticks in 3rd, then you've got to give it the beans up to about 5.5k and then let of the throttle quick and it will shift.You know that's not normal, right
...drove with original ATF about 280 000 km, I remember that when engine and gearbox were cold and I went directly to highway I had some delayed shifting from 2 to 3 or 3 to 4. After having changed oil about a year ago I did not have this behavior any longer. Perhaps nothing to do with the old oil but that happened to me.
