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.
Re: Who makes 6-speed HD Automatic 68RFE Transmission. I have been told by more than one person that it is based on the 45rfe, which is the transmission in hemi trucks.In turn, that was a new design when it came out, not based on the old 727 architecture.e: Who makes 6-speed HD Automatic 68RFE Transmission. Yesturday I went to the Cummins dealer here. The shop manager said that Chrystler owns the company that makes the new 68erf transmission.
