transmission is, why the diagram matters, and how to interpret it effectively.

What Is the A606 42LE Transmission?

Before diving into the diagram itself, it’s important to understand what the A606 42LE

transmission is. The A606, also known as the 42LE, is a four-speed automatic transmission

produced primarily by Aisin-Warner and used in various Chrysler vehicles during the

1990s and early 2000s. This transmission is known for its durability and smooth shifting,

making it a popular choice among car manufacturers and drivers alike.

The “42LE” designation generally refers to the four forward gears (“4”), the series

designation (“2”), and “LE” indicating it’s a lock-up transmission with electronic controls.

This transmission was commonly found in Chrysler, Dodge, and Jeep models, as well as

some Mitsubishi vehicles.

Why Is the A606 42LE Transmission Diagram Important?

When working on or trying to understand the A606 42LE transmission, the diagram serves

as a roadmap. It visually represents the complex network of components, including the

hydraulic circuits, clutch packs, valve body, torque converter, and electronic solenoids.

Without a proper diagram, diagnosing transmission problems or performing repairs can

feel like navigating a maze.

A detailed A606 42LE transmission diagram helps you:

Identify individual transmission parts and their relationships.

Understand the flow of hydraulic fluid that controls gear shifts.

Pinpoint potential failure points or wear areas.

Perform accurate repairs or rebuilds with confidence.

Improve troubleshooting efficiency by visualizing the transmission’s operation.

Breaking Down the A606 42LE Transmission Diagram

Key Components Highlighted in the Diagram

The transmission diagram typically breaks down the A606 42LE into several critical

components:

Torque Converter: Connects the engine to the transmission and allows for smooth

1.

power transfer.

Planetary Gear Sets: Provide the different gear ratios necessary for the

2.

transmission’s four speeds.

Clutch Packs and Bands: Engage and disengage specific gears by locking or

3.

releasing parts of the planetary gear sets.

Valve Body: The hydraulic control center that directs fluid to the appropriate

4.

circuits to facilitate gear changes.

Solenoids and Sensors: Electronic elements that manage hydraulic flow and

5.

control shifting electronically.

Output Shaft: Transfers power from the transmission to the driveshaft and

6.

ultimately to the wheels.

Hydraulic Circuit Visualization

One of the most critical aspects of the A606 42LE transmission diagram is the depiction of

the hydraulic circuits. These circuits use pressurized transmission fluid to engage clutches

and bands, enabling gear changes. The diagram usually illustrates:

The path of transmission fluid from the pump through various valves.

1.

How pressure is routed to specific clutches or bands based on the selected gear.

2.

Locations of pressure regulators and accumulators that smooth out shifts.

3.

Understanding these hydraulic pathways is essential for anyone troubleshooting slipping

gears, harsh shifts, or delayed engagement.

How to Read and Use the A606 42LE Transmission Diagram

Effectively

Start with the Basics

When first looking at an A606 42LE transmission diagram, it can be overwhelming due to

the number of components and fluid channels. Begin by familiarizing yourself with the key

parts mentioned above. Identify the torque converter, planetary gear sets, valve body,
