Hi Everyone.
I have a Omega CDX 2.6 V6 Auto.
It has just developed a worrying "thump" when changing up into top gear. This seems to happen mostly when in cruise is set at 32 mph and when it has reached cruise speed. It doesnt seem to happen if out of cruise and driving at normal open road speeds like 40 plus.
I have read on the forum about ECU upgrades etc but not having a technical head don't understand any of this.
I live in the Grimsby, Lincolnshire area and am not aware of any gearbox specialists i can contact locally. There is, however, a Vauxhall main dealer but am reluctant to go there yet for fear of their notoriously costly solution.
Any advice would be very much appreciated so thank you in advance.
