GEAR BOX TOO SHORT

2006 Fiat Doblo

Transmission problem
2006 Fiat Doblo 4 cyl Two Wheel Drive Manual 12000 miles

I HAVE A DOBLO 1.4 8 Valves model 2006 WITH HIGH ROOF. NOW 18000 km.
MY PROBLEM IS THAT THE 5th SPEED OF GEAR BOX IS TOO SHORT AND CANT DRIVE TO HIGH WAY UP TO 120 KM/HOUR WITHOUT NOISE OF THE ENGINE AND TOO HIGH CONSUMPTION OF FUEL.

I WANT TO CHANGE THE 5th " SPEED" OF MY GEAR BOX.
I CAN " GIVE" TO ANYONE ALL THE NUMBERS ON MY GEAR BOX AND PICS OF IT ( AND THE GEARS OF THE 5th SPEED ).

THE BIG GEAR HAS 38 TEETH AND THE SMALL GEAR 35 TEETH ( OF 5th SPEED ).

PLEASE NEED HELP.


Note: FOR 140 KM/HOUR THE ENGINE WORKS ON 5400 RPM AND 16 LITRES / 100 KM.

SORRY FOR MY ENGLISH

Changeing the gearbox will not supply any more power. You have a very small engine size !
