The vehicle I want economy from is a 1955 Pontiac Star Chief ( almost 4000 lbs and square as a brick. It has the very old dual range Hydro Matic without a park position. Economy is one factor, another is, who knows how to fix it id it breaks?

Van get a $800 adapter and put a GM overdrive trans behind the engine for about $2500 Total, will pay for it,self in 40,000 miles.At 69 and with various heath issues, driving 5,000 miles a year, that is a chancey bet.

I could put a Gear Venders OD behind the hydromatic for about $3,500, then I still have the worry of the original trans.
