add transmission type to vehicle profiles
I suggest adding a "Transmission Type" to the model specification for vehicle profiles, along with engine type, body style, year, etc.
Many vehicles are sold with the same engine paired to very different transmission options. Those of us who are stick-shift fans have to hunt to find the relatively few instances of vehicles with manual transmissions.
Fuel economy performance under real conditions varies significantly when the only difference between two models is automatic vs. manual. All possible transmission permutations should be represented: conventional automatic, CVT, and manual, and number of speeds if more than one range was offered for that particular model year (rare these days, but many models once had a choice of 4 or 5 speed manual).
