Re: OD trans, engine configurations, highway fuel mileage goals
One last important factor to consider when choosing rear-end gear ratios with an overdrive transmission.
The higher numerically the first gear in the transmission is, the more leverage the transmission has on itself to self destruct under heavy load and abuse.
Running a 3.54 Dana 44 gearing behind the ax15 will be a slight bit more forgiving when getting on it when hauling a heavy load, compared to the same condition with a 3.31 differential gearing.
