Torque converter automatic transmission Chrysler Sebring
The automatic transmission torque converter is an important transmission component that ensures the transmission of torque from the engine to the gearbox. The Chrysler Sebring automatic transmission uses a 42RLE torque converter, which has a number of unique characteristics and components.
Operating principle of the torque converter:
The torque converter consists of three main elements:
* Impeller (pump): Connected to the engine and rotates with it, creating a flow of working fluid (ATF).
* Reactor: A stationary wheel that redirects the flow of ATF back to the pump.
* Turbine: Connected to the transmission and driven by ATF.
As the pump rotates, ATF is directed to the turbine, causing it to rotate. This power transfer occurs without direct mechanical contact, resulting in smooth gear changes.
Features of the 42RLE torque converter:
* Torque Converter Lockup: Locks the turbine and pump under certain conditions (high speed, low load), increasing power transfer efficiency.
*Multi-stage clutch: Used to gradually transfer power from the pump to the turbine, ensuring smooth gear changes.
* Turbine Pedestal: Contains a freewheel that allows the turbine to spin faster than the pump under gear shift conditions.
* Variable Displacement Pump: Adjusts ATF pressure based on load and speed, improving transmission efficiency.
Replacing the torque converter:
Replacing the torque converter may be necessary if any of its components wear out or wear out. This is a complex procedure that requires special tools and knowledge. It is recommended that you have the torque converter replaced by an experienced mechanic.
Torque converter maintenance:
To ensure optimal torque converter performance, it is important to perform the following on a regular basis:
* Timely replacement of transmission fluid (ATF)
* Replacing the automatic transmission filter
* Diagnose and repair any ATF leaks
