Essential Hand Tools
First and foremost, an indispensable tool for any transmission rebuild is a good torque wrench. A torque wrench allows you to tighten nuts and bolts to the specified torque, preventing over-tightening or under-tightening. In this video, I showcase an old dial-style torque wrench, which can be calibrated by zeroing the dial to the desired torque. This tool is a genuine vintage piece inherited from my grandfather, but you can find modern torque wrenches in various sizes and configurations to suit your needs.
To assist in removing clutches and performing other tasks, I have created my own set of custom tools using aluminum rods. These tools allow me to reach difficult-to-access areas and provide the necessary leverage to pull up on clutches or snap rings. While it is possible to find similar tools on the market, crafting your own customized set gives you the freedom to create tools that cater specifically to your needs.
Snap ring pliers are another must-have tool. In the video, I showcase my favorite set, which has a unique tip design that works exceedingly well. However, it is always good to have alternatives with different gap sizes, like the larger snap ring pliers I have for opening gaps and smaller, more precise ones for delicate tasks. Nipex is an excellent brand of pliers, though they come at a higher price point. Investing in high-quality tools like these ensures longevity and reliability, a far better alternative to cheaply-made tools at stores like Harbor Freight.
Next on our list of essential hand tools is a pick set, which proves to be incredibly useful in removing seals and other small components. The pick set shown in the video is my personal favorite, but there are many options available on the market, including 90-degree picks and hook picks. While brands like Matco and Cornwell offer high-quality pick sets, you can find reasonably priced options at stores like Harbor Freight without compromising on precision and quality.
Additionally, it is crucial to have metric sockets, a micrometer for precise measurements, and a good set of feeler blades for achieving proper clearances. These tools are necessary for ensuring accurate measurements and maintaining optimal performance.
Tools for 4L60 Transmission Rebuild
Moving on to the specific tools for rebuilding the 4L60 transmission, there are several items you will need. A vital tool for this process is the 2-4 band pin length measurement tool, which allows you to ensure the band has the correct length. In the video, I demonstrate the tool I use, which carries the part number J33037. This tool can be found on websites like eBay, but it is crucial to ensure that it comes with the necessary sleeve for accurate measurements.
Another tool you’ll need is the stator support ring sizer for the pump. This tool ensures that the stator support rings fit properly on the pump. There is an accompanying installer, which is used to slide the rings onto the pump without damaging them. These tools, with the part numbers 39-855-2 and 39-855-1, respectively, are essential for a successful 4L60 rebuild.
The stator shaft seal installer, with the part number 36418-1B, is another necessary tool for the 4L60 rebuild. This tool slides over the input shaft, protecting the seals during installation. It is crucial to ensure this tool remains intact during use for optimal functionality.
Additionally, you will need a seal sizer, like the one with the part number 38-418-2A. This tool is essential for correctly sizing the seals during assembly. While digital calipers can be used as an alternative, I find seal sizers to be more accurate.
Tools for 4L80E Transmission Rebuild
For those looking to rebuild the 4L80E transmission, there are specific tools required as well. One critical tool is the lip wizard, which aids in installing drums where seals are present. The lip wizard slides between the seal and the drum, allowing for smooth installation without damaging the components. Although different versions of this tool are available, the one shown in the video proves to be highly effective.
Another essential tool for the 4L80E rebuild is the spring compressor. While there are various designs available, the one displayed in the video features two legs that can be adjusted to fit different pistons. This tool is used to compress springs during assembly and disassembly. However, it is worth noting that this tool can become cumbersome in some cases and may not be suitable for every situation.
In the video, I also present a tool I personally favor for working with the low-reverse piston in the 4L80E transmission. This unique tool, constructed using a large bolt and an aluminum sleeve, provides excellent functionality while avoiding the use of complex snap rings. The part numbers for the Mouse Trap tools demonstrated are 38-734 and 23-387, with an additional bottom plate marked as J21-420-2.
Conclusion
In conclusion, these are the essential tools you will need for rebuilding the GM700R4, 4L60e, and 4L80E transmissions. From torque wrenches to seal installers, having the right tools can make a significant difference in the efficiency and accuracy of your rebuilds. Investing in high-quality tools ensures durability and precision, allowing you to tackle various transmission projects with confidence. So, equip yourself with these essential tools, and get ready to rebuild your transmissions like a pro!
