12. Transmission Torque Converter

The torque converter is a vital component of an automatic transmission, acting as a fluid coupling between the engine and the transmission. It plays a crucial role in smooth power transfer and enhancing vehicle performance.

Detailed Operation

The torque converter consists of four main components:

• Stator:A stationary component that directs the flow of hydraulic fluid, creating torque multiplication.
• Impeller:Attached to the engine crankshaft, it pumps the hydraulic fluid when the engine rotates.
• Turbine:Connected to the transmission input shaft, it receives the fluid from the impeller and rotates the transmission.
• Reaction Shaft:This shaft connects the stator to the transmission case and helps maintain the stator’s position.

Hydraulic fluid, usually ATF (Automatic Transmission Fluid), plays a critical role in the torque converter’s operation. The fluid transmits power from the engine to the transmission by transferring energy through its movement. As the impeller spins, it pumps the fluid towards the turbine, causing it to rotate.

The stator directs the fluid flow, amplifying the torque transferred to the turbine.Torque multiplication is a key function of the torque converter. When the engine is accelerating, the impeller spins faster than the turbine, creating a pressure difference within the fluid.

This pressure difference, coupled with the stator’s action, results in a higher torque output at the turbine than the input torque at the impeller. This torque multiplication enhances vehicle acceleration and performance.The “stall speed” refers to the engine speed at which the vehicle is stationary but the engine is running.

At stall speed, the torque converter is not locked, allowing the engine to provide maximum torque for acceleration. This is especially useful for situations like hill starts or heavy loads.A lock-up torque converter differs from a conventional one by engaging a clutch mechanism at higher speeds.

This locks the impeller and turbine together, eliminating slip and improving fuel efficiency. However, lock-up converters can sometimes cause harsh shifts or vibrations if not properly maintained.

Potential Malfunctions

13. Transmission Clutches and Bands

The transmission clutches and bands are essential components in the smooth operation of your 2017 Silverado’s automatic transmission. These components are responsible for engaging and disengaging power flow between the engine and the transmission, ultimately determining the gear ratios and allowing for seamless gear changes.

Understanding how they work and the common problems associated with them is crucial for maintaining the longevity and performance of your vehicle’s transmission.

Function of Clutches and Bands

The clutches and bands within your transmission are critical for transferring power and changing gear ratios. They work in tandem to allow for smooth and efficient gear changes.

• Clutch:A clutch is essentially a friction plate that engages and disengages the power flow between the engine and the transmission. It consists of two main parts: a pressure plate and a friction disc. When the clutch is engaged, the pressure plate clamps the friction disc against the flywheel, transferring engine power to the transmission.

  When the clutch is disengaged, the pressure plate releases the friction disc, interrupting the power flow. This allows for gear changes and smooth transitions between different speeds.

• Band:A band is a flexible steel band that wraps around a drum within the transmission. It is used to apply pressure to the drum, which changes the gear ratios within the transmission. The band is connected to a hydraulic actuator, which is controlled by the transmission control module (TCM).

  When the TCM signals for a gear change, the actuator applies pressure to the band, tightening it around the drum and changing the gear ratio. This process is similar to how a brake caliper uses brake pads to slow down a wheel.

In essence, clutches are responsible for the initial engagement and disengagement of power, while bands are responsible for fine-tuning the gear ratios within the transmission.

Common Problems with Clutch and Band Wear

Wear and tear on clutches and bands are inevitable over time due to the constant friction and pressure they experience. This wear can lead to a variety of transmission problems.

• Clutch Slippage:This occurs when the clutch plates lose their ability to grip properly. Symptoms include:
  • Sluggish acceleration
  • Increased engine RPM without a corresponding increase in vehicle speed
  • A burning smell from the transmission
• Band Wear:Worn bands can cause a variety of issues, including:
  • Difficulty shifting gears smoothly
  • Slipping or jerking during gear changes
  • A slipping or clunking sound when shifting
• Clutch or Band Failure:Complete failure of a clutch or band can lead to:
  • Inability to shift gears
  • Transmission locking up
  • Severe damage to the transmission

Inspecting and Replacing Clutches and Bands

Regular inspection and timely replacement of worn clutches and bands are crucial for maintaining the health of your transmission.

• Inspection:
  • Visually inspect the clutches and bands for wear, tear, and damage. Look for signs of excessive wear, cracks, or burnt material.
  • Use a micrometer to measure the thickness of the clutch plates and the width of the band. Compare these measurements to the manufacturer’s specifications.
  • Check for any signs of contamination or debris in the transmission fluid.
• Replacement:
  • Removal:Remove the transmission from the vehicle and carefully disassemble it. This involves removing the valve body, torque converter, and other components to access the clutches and bands.
  • Installation:Install the new clutches and bands, ensuring that they are properly aligned and seated. Use the correct torque specifications when tightening bolts and nuts.
  • Adjustment:Adjust the clutches and bands after installation to ensure proper engagement and operation. This may involve using special tools and following the manufacturer’s instructions.

Warning:Transmission work can be complex and potentially dangerous. It is crucial to have the proper tools, knowledge, and safety precautions in place before attempting any repairs. If you are not comfortable with the task, it is best to seek professional assistance from a qualified mechanic.
