Understanding the 62TE Transmission and Its Check Balls
What Is the 62TE Transmission?
The Chrysler 62TE transmission is a 6-speed automatic transmission commonly used in various Chrysler, Dodge, and Jeep models. It is an evolution of earlier transmission models designed to improve fuel efficiency, shift quality, and durability. This transmission features a complex hydraulic control system that relies heavily on check balls to regulate fluid flow and valve operation.
The Role of Check Balls in the 62TE Transmission
Check balls are small, spherical components typically made of steel or other durable materials. They serve as one-way valves within the hydraulic system, allowing fluid to flow in one direction while preventing backflow. Their primary functions include:
- Controlling fluid pathways in the valve body
- Engaging or disengaging clutches and bands
- Ensuring proper gear shifts and smooth operation
- Preventing internal leaks and maintaining hydraulic pressure
Incorrect placement or loss of check balls can cause shifting problems, fluid leaks, or complete transmission failure.

Locating the Check Balls in the 62TE Transmission
General Overview of Check Ball Placement
The 62TE transmission's hydraulic control system is centered around the valve body, which contains various channels, valves, and check balls. The exact location of check balls varies depending on the specific model year and transmission revision, but they are generally found in the following areas:
- Valve body assembly
- Specific hydraulic circuits controlling gear engagement
- Shift solenoid zones
- Hydraulic pump and valve body interface
Common Check Ball Locations in the 62TE Transmission
Below are the typical check ball positions within the 62TE transmission, along with their functions:
1. First Gear Clutch Control Check Ball
- Location: In the valve body, often in the first gear clutch control circuit.
- Function: Prevents fluid backflow, ensuring proper clutch engagement during first gear.
2. Reverse Clutch Control Check Ball
- Location: In the reverse circuit pathway within the valve body.
- Function: Ensures reverse gear engagement by controlling fluid flow to reverse clutches.
3. Overdrive (OD) Check Ball
- Location: In the OD circuit, usually near the overdrive servo control.
- Function: Regulates fluid flow to enable or disable the overdrive gear.
4. Intermediate and Low Gear Check Balls
- Location: In circuits controlling intermediate and low gears.
- Function: Maintain proper hydraulic pressure and prevent unintended engagement.
5. Park/Neutral Position Check Ball
- Location: In the park/neutral safety circuit.
- Function: Ensures the transmission is fully engaged in park or neutral, preventing movement.
Note: Exact positions may vary based on specific transmission revisions; always consult the official repair manual or detailed diagram for your model year.
