How to Remove a Transfer Case from a 4L60E Transmission: A Comprehensive Guide
When working on your vehicle, especially a 4x4 model from the 80s or 90s, one task that may arise is the removal of the transfer case from the 4L60E transmission. This guide aims to provide an easy-to-follow and straightforward step-by-step process to help you accomplish this task efficiently, without the need for expensive tools.
The Process of Removing the Transfer Case from a 4L60E Transmission
Before you start the process, it's important to understand that the transfer case typically unbolts from the transmission, the driveshafts, and the mounts. This process is relatively straightforward and much simpler than removing the transmission or a front-wheel drive (FWD) transmission. The vehicle models listed in this guide cover an extensive range of 4x4s from the 80s and 90s. For detailed steps, please refer to your specific vehicle's manual.
Tools and Equipment Needed
To carry out the transfer case removal, you will need a selection of tools. Here is a list of the basic tools you will need:
A socket and ratchet set A torque wrench (if specified in the manual) A transmission jack (homemade or store-bought) A 2x2 plate (optional) A small stainless steel pan with 1-inch raised edges (optional) A jack plate (optional) A floor jack (if a transmission jack is not available) Jack stands (if necessary) A jack handle (if the jack requires it) A lubricant (optional)Step-by-Step Guide
Step 1: Preparation and Safety Check
Before you begin the process, ensure your vehicle is safely supported on jack stands. Use a lug wrench or similar tool to steady the vehicle and avoid it from rolling. Before removing any components, disconnect the battery to ensure the vehicle is not accidentally started.
Step 2: Removal of the Transfer Case
Using the socket and ratchet set, remove the bolts connecting the transfer case to the transmission, driveshafts, and mounts. These bolts are typically hex or Allen type and may require socket extensions for better access. Removal of the bolts will free the transfer case from its position.
Step 3: Using a Homemade Transmission Jack
A homemade transmission jack can be quite effective and cost-effective. To make one, use a floor jack as a base and then place a 2x2 plate in its place. On top of the plate, place a slightly smaller stainless steel pan with 1-inch raised edges. This setup will provide a stable and safe platform to cradle the transmission. Secure the jack and pan with a bolt, ensuring the transmission is properly supported.
Step 4: Lifting the Transmission
Once the transfer case is removed, use the homemade transmission jack to lift the transmission. Deploy the jack handle and lift the transmission slightly off the ground. Ensure the transmission is securely supported on the homemade jack plate.
Step 5: Finishing Touches
While the transmission is in the air, you might need to reposition it slightly to ensure all bolts and connections are clear. Make sure all moving parts are properly lubricated if necessary. Once you are satisfied with the position, carefully lower the transmission back onto the vehicle.
Conclusion
The process of removing a transfer case from a 4L60E transmission is not as daunting as it may seem, especially when using a homemade transmission jack. These homemade solutions not only save you money but also provide a secure and stable platform for lifting and positioning the transmission safely. With the right tools and a steady hand, you can complete this task efficiently and without the need for expensive equipment.
Frequently Asked Questions
Q: Can I use a regular floor jack instead of a homemade transmission jack?
A: Yes, you can use a regular floor jack. However, using a homemade jack (described in this guide) can provide additional safety and support, making the process easier and less risky.
Q: What if I don't have a transmission jack?
A: You can always use a regular floor jack, but make sure it is properly supported and stable to avoid any accidents. It is recommended to use a homemade transmission jack for added safety.
Q: Do I need any special lubricants while removing the transfer case?
A: Depending on the manual, you might need a lubricant to make the removal process smoother. However, it is not a necessary step in most cases.
