The 45RFE was introduced in the Jeep Grand Cherokee in 1999, it is notable for including three planetary gearsets rather than the two normally used in a 4-speed automatic. It also features three multiple disc input clutches, three multiple disc holding clutches, and a dual internal filter system (one primary filter for transmission sump, one for the fluid cooler return system).
2007–present 68RFE — 6-speed heavy-duty automatic; 2005-2019 Chrysler A580 / W5A580, 5-speed automatic. This was a Chrysler adaptation of the Mercedes 5G-Tronic. The A580 was first labelled as the NAG1. Commonly found in the 300, Magnum, Charger, Challenger, WK/WK2/WD Grand Cherokee and Durango (through 2013), Wrangler, and some Dodge Ram ...
A replacement automobile engine is an engine or a major part of one that is sold individually without any other parts required to make a functional car (for example a drivetrain). These engines are produced either as aftermarket parts or as reproductions of an engine that has gone out of production.

The RE is an electronic hydraulic system that is considered for heavy-duty use. Both transmissions are also used in the Dodge Dakota and Jeep Cherokee among other Chrysler models. Gear ratios in both transmissions are 2.74:1 for first gear, 1.54:1 for second gear, 1.00:1 for third gear, and 0.69:1 for fourth gear. [23]
However, there are various exceptions to this, such as the straight-eight engines used by various luxury cars from 1919-1954, [1] [2] [3] V4 engines used by some marine outboard motors, V-twin and flat-twin engines used by motorcycles and flat-four engines used by various cars.
Internal combustions engines require lubrication in operation that moving parts slide smoothly over each other. Insufficient lubrication subjects the parts of the engine to metal-to-metal contact, friction, heat build-up, rapid wear often culminating in parts becoming friction welded together e.g. pistons in their cylinders.
Some types of mechanical failure mechanisms are: excessive deflection, buckling, ductile fracture, brittle fracture, impact, creep, relaxation, thermal shock, wear, corrosion, [1] stress corrosion cracking, and various types of fatigue. [2] Each produces a different type of fracture surface, and other indicators near the fracture surface(s).
