Automatic gearbox issues

[Frederic]

Hi all,

I'm having some serious automatic gearbox issues with my Vectra C MY06, 1.9 150bhp.

For a couple of weeks now, the gear changes are very harsh. This only occurs when the engine is at operating temperature. Especially between 2nd and 3rd, the revs climb with approx 2000 (doesn't matter if you keep your foot on the pedal or keep it on), and the car jerks and bumps as is if it could fall apart any moment.
Sometimes, this happens between the other ratios, but mainly between 2nd and 3rd.
The car has been to the dealer 2 times, but they can't find anything :/
Does this problem sound familiar?

Thank you!!

Sounds like a busted valve body, but if the same dealer did't find the problem twice, I'd say it's time to change the garage.

Have you changed the transmission fluid?
