Default Transmissions: Gears & Axle Ratios

A new automatic (MDK) Aisin-Warner A6-AF40 transmission was added with the 2014 Turbo Diesel Cruze:



A new manual (MR5) transmission was added for the LT models. Notice the top gear artios (3rd thru 6th) are the same as in the MZ0 transmission.

Yes. the original 3.87:1 axle ratio will be quicker than the new 3.53:1 axle-ratio, but the new 3.53:1 axle-ratio will get better highway milage...proportedly 2 MPG better.
