Jim Jennings Transmissions performs hundreds of transmission maintenance procedures every year. These photos show what we find when we remove the transmission's sump pan during a service.The amount of debris helps us get a sense of the health of an automatic transmission based on what has worn off it's 1,000's of parts previous to the pan's removal. The less debris we find, the brighter the transmission's future.

This gallery shows the various models of transmissions used in cars and light trucks. Some are disassembled or "cut-a-ways" for better viewing.

• Cut-a-way Rear Wheel Drive Transmission
• CVT (Continuously Variable Transaxle)

Since computers started managing transmission in the eighties, transmission professionals had to develop highly tuned electronic diagnostic skills to go along with their mechanical and hydraulic capabilities. Shown in the following photos are examples of problems we have found in the electrical and electronic side of the modern automobile.

• Exposed Wire
• Grounded Wires
• Melted Wire Insulation
• Corroded Battery Terminal
• Chewed Wire Insulation

This is an example of a modern automatic transmission's torque converter. It's the component that allows the vehicle to come to a complete stop without depressing a clutch pedal. It essentially works because transmission fluid is moved by a turbine, which is being turned by the engine's crankshaft, against another turbine connected to the front of the transmission. As you increase the speed (rotation) of the engine, it moves fluid against the other turbine causing it to turn to provide rotational power to the transmission. It loses 6% of the energy produced by the engine and a clutch was added inside the converter (as early as 1978) which connects the turbines together gaining the lost 6% of the engine's power. The clutch lining tends to glaze or wear causing a "rumble strip" feel above 35 miles per hour on light to medium throttle.
