i have a trans problem with my '00 3.0 omega auto. when it gets warm it won't chainge in to higher gear until high rpm,and then suddenly it chaingens with a big jolt.anybody had similar problems? p.s it is an AR35 automatic trans,and i mainly drive it in 3,and i use D only for the higway

Why leave it in 3? Why not put it in D all the time?
-
Should be in D all the time mate,
your just putting under undue strain on the transmission for no good reason.

There used to be lots of threads on the old forum about thumping gear changes but I can't find them at the moment :-\
A possible cause is low fluid level. Have a read of How to check the autobox fluid level (http://www.omegaowners.com/forum/index.php?topic=90508.0)
Other possible causes are a disintegrating thrust washer or faulty solenoid.
Before taking anything apart (or spending money) you would be well advised to get the codes read in the gearbox ECU and engine ECU using Tech2. Post the results on here and someone will be able to direct you to the cause :y

I drive it in 3 because i don't want it to be shift in to fourth when high-speed driving trough curvy mountain roads(where i mostly drive it),this way i can engine break when i need to. For city i drive my 2.5 dti 5 speed auto and i drive it i D all the time.
Any way, changed the ATF gaskets on the two sumps,cleaned the magnet on the main sump. I poured in about 5.3L of ATF,although it tells 4.4l in AutoData, it was not enough.
My uncle owns an Opel repair shop and a parts store, i work there part time,so it is not a cost for my to do anything on my cars, but we don't have a clue about automatic transmissions. I will see how the omega drives after the trans oil change and post it here. P.S.Tech3 did not read any errors. Thanks for your advices.
