What is the 42RE transmission?
The 42RE is a four-speed automatic transmission that was produced by the Chrysler Corporation. It was introduced in 1989 and was used in a number of Chrysler vehicles, including the Jeep Grand Cherokee and the Dodge Ram. The 42RE is a reliable and durable transmission that offers smooth shifting and great performance.
Features of the 42RE transmission
The 42RE transmission comes with a number of features that make it unique. Some of these features include:
| Feature | Description |
|---|---|
| Electronic controls | The 42RE is controlled by an electronic module that monitors and adjusts the transmission’s functions for optimal performance. |
| Overdrive | The 42RE has an overdrive gear that allows it to operate at lower RPMs, reducing engine wear and increasing fuel efficiency. |
| Lockup torque converter | When the transmission is in overdrive, the torque converter locks up, providing a direct drive that reduces slippage and improves efficiency. |
How does the 42RE transmission work?
The 42RE transmission operates using a hydraulic system that is controlled electronically. The transmission fluid is pumped through the transmission by the torque converter, which is powered by the engine. The fluid is then directed to the appropriate clutch pack or band by the valve body, which is controlled by the electronic module.
