Main Responsibilities. Marine engineers are responsible for the design, maintenance and repair of the various mechanical systems in a ship. A marine engineer often works closely with the architect who designed the initial blueprint for a shipâs structure.
The transmission wildcard here is the Ram truck. Ram doesnât offer a medium-duty-truck transmission in its pickup. So weâve chosen to compare the automatics from Ford and GM to the Aisin Seiki AS68RC six-speed found in Ramâs cab-and-chassis trucksâand not the 68RFE six-speed used in Ram pickups. Will this Aisin Seiki be the next transmission offered in the Ram pickup once its power goes up? We wouldnât be surprised.
The AOD (for automatic overdrive) is a four-speed automatic transmission with overdrive. Introduced in 1980, it was Ford 's first four-speed automatic overdrive transmission. The gearset design is based on the Ford X automatic transmissions used during the 1950s, 60s, and 70s.n 2003 Ford revised the 4R70W transmission with a stronger ring gear that had 24 lugs, as opposed to 6, for the output shaft sensor (OSS) to read off of, a new torque converter, a revised front pump assembly, and a vehicle speed sensor (VSS) that compliments the OSS to improve shift quality and efficiency.
