Hello!
First time poster here.
I own a 2011 Exeo ST high milage one, aprox. 231k miles. Engine seems fine but the gearbox is too "long".
I did the math: 6'th gear @ 5000 revs = 314 km/h ( ~196 mph). It's a 3.3:1 differential with final ratio of 1.897:1.
I bought a second hand transmission HCK code. It has a 3.75:1 diff and a final ratio of 2.156:1. Top speed in final gear will be 276 km/h ( ~172 mph).
Wheel torque will be up by 13.6% except for 5'th gear witch will be 17.6 up.
I hope it will make my car more drivable since i find myself between gears quite often.
Here's my question:
Will i need some sort of ECU coding? It has gear suggestion in the MFD. Will it work ok after the replacement? How about vehicle speed? I hope it reads speed from the ABS sensors.
Thank you!
Sorry for the wall of text.
