How to Remove a 4L60E 4x4 Transmission
The 4L60E transmission is a four-speed automatic transmission that was used in a variety of GM vehicles from 1993 to 2007. It is also known as the 4L60E-HD, which stands for "Heavy Duty." The 4L60E is a popular transmission for use in off-road vehicles because it is strong and durable. If you are planning to remove a 4L60E transmission from a 4x4 vehicle, there are a few things you need to keep in mind.
Safety First
Before you begin any work on your vehicle, it is important to take safety precautions. Wear eye protection, gloves, and appropriate clothing. Make sure to disconnect the battery negative terminal to prevent any electrical accidents.
Tools and Materials
You will need the following tools and materials to remove a 4L60E transmission:
- Socket set
- Wrench set
- Transmission jack
- Drain pan
- Fluid funnel
- New transmission filter and gasket
- New transmission fluid
Step 1: Remove the Driveshaft
The first step is to remove the driveshaft. The driveshaft is the metal tube that connects the transmission to the rear differential. To remove the driveshaft, you will need to unbolt the U-joints at both ends of the driveshaft.
