Hey gearheads! So, you're here because you're diving into a Ford MX transmission rebuild, huh? Awesome! The Ford MX transmission, also known as the Mazda MX-5 Miata transmission, is a robust piece of machinery. But like any mechanical marvel, it eventually needs some TLC. That's where the Ford MX transmission rebuild kit comes into play. This guide is your one-stop shop for everything you need to know about these kits, from what they include to how to choose the right one for your specific needs. Let's get down to business and get your Miata shifting smoothly again!

What's Inside a Ford MX Transmission Rebuild Kit?

Alright, let's crack open the toolbox and see what a Ford MX transmission rebuild kit typically contains. Think of it as a care package for your transmission, filled with all the goodies it needs to bounce back to its former glory. Generally, you can expect to find:

• Gaskets and Seals: These are the unsung heroes of the transmission world. They create a watertight and airtight seal, preventing those nasty leaks that can leave you stranded. A comprehensive kit will include a variety of gaskets and seals designed to fit perfectly within your transmission's design. Without high quality gaskets and seals, you'll be dealing with leaks and other problems faster than you can say 'transmission trouble.' Make sure to pay close attention to the quality of the material. There are many different types and they do have an impact in the life of the rebuild.
• O-Rings: Similar to gaskets and seals, but often smaller and used for more specific applications. They prevent fluid from escaping at various points within the transmission's components. Consider them mini-seals.
• Seals: Often rubber or rubber-like components that act as barriers against oil leakage. Replacing seals is crucial to prevent fluid loss and maintain proper transmission function.
• Bearings: These little guys are essential for smooth operation. They allow the gears to spin with minimal friction. A good kit will have a full complement of bearings, including ball and roller bearings, to replace worn-out ones and ensure everything spins as it should. Always replace the bearings in a transmission rebuild. A faulty bearing can take down an entire transmission quickly.
• Synchro Rings (Synchronizer Rings): These components are vital for smooth shifting. They help synchronize the speed of the gears, making it easier to shift between them without grinding or clashing. A complete kit will have synchro rings for all gears.
• Clutch Discs (Friction Discs): Though the Ford MX transmission isn't an automatic, there are still clutch-related components like friction discs, especially on the input shaft, that might be included in some kits. These help the transmission engage and disengage the engine's power. Check the contents of your kit carefully to ensure you have what you need.
• Small Parts: Depending on the kit, you might find other smaller bits and pieces, like snap rings, thrust washers, and other hardware necessary for a complete rebuild. These are the details that separate a good kit from a great one!

This list isn't exhaustive, as the specific contents can vary between kits. However, it gives you a solid idea of what to expect when you open up a Ford MX transmission rebuild kit. So, before you start wrenching, take a close look at the kit's contents to make sure it includes everything you need for your particular transmission. Check that the kit covers your specific model year and any modifications you might have made to your transmission, such as upgrading clutch plates.

Choosing the Right Ford MX Transmission Rebuild Kit

Now, let's talk about choosing the right Ford MX transmission rebuild kit. Not all kits are created equal, and selecting the wrong one can lead to headaches down the road. Here's a quick guide to help you make the right choice:

• Identify Your Transmission Model: The Ford MX transmission was used in various vehicles, and there can be slight differences between models. Before you buy anything, make sure you know the exact model of your transmission. This information is usually found on a tag or stamped on the transmission housing.
• Consider Your Needs: Are you just fixing a leak, or are you doing a full-blown rebuild? If it's a simple fix, a basic kit with gaskets and seals might suffice. But if your transmission has been through the wringer, a more comprehensive kit with bearings, synchros, and other components is the way to go.
• Quality Matters: Don't skimp on quality! Opt for kits from reputable manufacturers that use high-quality materials. Cheap components can fail quickly, leading to more problems and wasted money down the road. Do your research by reading reviews. Reviews are great for understanding the quality of the product. The best way to understand the quality of the product is to read reviews from other customers.
• Check the Contents: Make sure the kit includes all the components you need. If you're rebuilding the entire transmission, a kit with gaskets, seals, bearings, and synchros is essential. If you are a beginner, it's generally best to go with a full kit, which includes all the parts you'll need.
• Read Reviews: See what other people are saying about the kit. Customer reviews can provide valuable insights into the quality, fit, and overall performance of the kit. Check out online forums and communities dedicated to the Ford MX-5 Miata to gather feedback.
• Consider Upgrades: If you're feeling ambitious, you might want to consider upgrading some of the components in your rebuild kit. For example, some kits include upgraded synchro rings or bearings, which can improve shifting performance and durability.

By following these tips, you'll be well on your way to choosing the right Ford MX transmission rebuild kit for your needs. Remember, a little research upfront can save you a lot of hassle and money later.

Step-by-Step: Rebuilding Your Ford MX Transmission

Alright, you've got your Ford MX transmission rebuild kit, and you're ready to get your hands dirty. Let's walk through the basic steps of a transmission rebuild. Please keep in mind, this is a general overview, and you should always refer to a detailed service manual for your specific transmission model. Safety first, always.

• Preparation: Gather all your tools, including sockets, wrenches, a torque wrench, a bearing puller, and a soft-faced hammer. Clean your workspace and make sure you have plenty of space. You'll also need a drain pan, and a way to support the transmission safely.
• Removal: Carefully remove the transmission from your vehicle. This usually involves disconnecting the driveshaft, shift linkage, and electrical connectors. Be sure to mark or photograph everything as you go, so you can reassemble it correctly. Don't forget to drain the transmission fluid before removing the transmission.
• Disassembly: Once the transmission is out, start by removing the bell housing, tail housing, and any external components. Then, carefully disassemble the transmission, taking note of the order of the parts. Use a service manual or online resources to guide you. Take lots of photos during disassembly to help you remember how everything goes back together. Place the small parts into containers so you don't lose anything.
• Cleaning: Thoroughly clean all the transmission components. Use a parts cleaner and a brush to remove any dirt, grime, or old fluid. Pay special attention to the internal passages and bores. A clean transmission is a happy transmission.
• Inspection: Inspect all the components for wear and damage. Check the gears for chipped teeth, the bearings for wear, and the synchros for wear. Replace any damaged or worn-out parts with the new components from your rebuild kit.
• Assembly: This is where the magic happens! Carefully reassemble the transmission, following your service manual and the photos you took earlier. Lubricate all the components with fresh transmission fluid as you go. Make sure all parts are in their proper place. Replace any parts you have replaced in the past with the ones that come with the kit.
• Installation: Once the transmission is assembled, reinstall it in your vehicle. Connect all the components you disconnected earlier, including the driveshaft, shift linkage, and electrical connectors.
