K2e2vin Senior Member Apr 1, 2009 #8 Shorter transmissions do not always mean lower MPG. "Aquafina" got like 45mpg with MFactory short gearset and 4.7FD. Not sure what motor but it's a D-series. I got 57mpg highway with a DOHC ZC transmission and 4.25FD, cruising around 3700-4000rpm. I/H/E and cammed D15B using P28 basemap.
