Hi all...
I have just collected my 30GV from gearbox change today. Noticed high rpm especially during high speeds. Before change, RPM is less than 2500 when cruising at 110~120km/h. But after change, RPM is almost 3000 at 120km/h !! Cant imagine how the fuel consumption will become!!
I'm quite frustrated after spending quite some big sum on the gbox change, and thought of getting some advice and comments form the sifus here while on the other hand highlighting this matter to the mechanic.
1. If, just in case, the mechanic mistakenly replaced the gearbox with a 2000cc gearbox, will the same thing happen?
2. Is there any ways to check whether the gearbox is meant for 3000 or 2000?
3. Could it be the ECU thingy? Should the ECU be recalibrated after gearbox change?
4. Or perhaps it's something to do with the sensors etc?
Anyone has any idea? Please help...

By the way, the idling rpm seemed ok (means similar to the previous one), but the engine will revv all the way to 3000rpm before gear shift. I'm pretty sure the same amount of force applied on the pedal, which in the previous gearbox it'll shift around 2500rpm.
