2010 xB 5 speed stick / Want taller gears..
Hello xB friends,
I'd like to know if there is a taller 5th gear for my manual transmission on the 2010 xB.
Or a manual transmission swap? Also, knowledge of a transmission person who has pulled off this change.
Thank you.

Welcome Marc. You still got your ears on? The 5th and 6th speed ODs on the newer 6 speed trannys don't have much of an OD either. It's almost worthless to go from direct (4th gear), into 5th because the spread is barely a couple hundred RPM drop. 6th is only marginally better. Haven't found out what the rear gear ratios are yet in these cars, but maybe because the 4 cyls. have so little power, they need to gear them low, to keep them in a higher power band. IDK. The stock 2014 tC runs about 3K RPMs at about 75 MPH. Someone on this site mentioned a Camery OD being better. Not sure if that'll pertain to your 5 speed. Keep posting.

The xB already has the tallest gear ratio for E35X series transmission so a straight gear swap isn't possible.
At one time there was a kit made to swap the 6 speed of the newer 2.5L engine to fit the earlier 2.4L. It was expensive and gained almost nothing in terms of fuel economy.

Yeah, taller gearing really makes minor difference in MPG. That's because at 65mph, it will still require exact same ~15hp to push car through air regardless of gearing.
Since Hp = (Tq*RPM)/5250 , lowering revs will require more torque to generate same HP. You'll have to use larger throttle openings with taller gearing. So MPG becomes a wash. It make bigger difference if you stray away from torque-peak/max-Ve of engine too far though.

Does anyone know what the final drive (differential) ratio is on a stick shift 2014 tC? I don't believe there are optional ones, but all the same. Don't know if the automatics are different from the stick shifts. I'm guessing something like 3 to 1, or maybe even 3.5 to 1.
