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.
Driving conditions generate heat in the transmission. Automatic transmission fluid cools the transmission components and allows for smooth transfer of power to the transmission for proper function. Different car makes and models require various types of automatic transmission fluid. Two common types are Dexron and Mercon. Mercon Mercon entered the market in 1987, according to the book The Role of the Chemist in Automotive Design by Herman K. Phlegm.
