Rebuilt Subaru transmissions are compatible with older Volkswagen models bringing them closer to modern standards of performance and efficiency. This is especially beneficial for enthusiasts looking to breathe new life into their vintage VWs.

Technical Considerations Before Conversion

Before you plan this upgrade, it’s important to address several key technical factors. Proper preparation ensures a seamless installation and maximizes the benefits of your new transmission.

Compatibility

While Subaru 5-speed transmissions are versatile, compatibility with your specific Volkswagen model depends on factors such as engine type, drivetrain configuration, and intended use. Consult with a professional or the manufacturer to verify suitability.

Core Exchange

Rebuilt transmissions typically require a usable core for exchange. If you don’t have a core to supply, be prepared for an additional $500 charge. This ensures you receive a fully rebuilt and functional transmission.

Installation Expertise

Installing a Subaru transmission in a Volkswagen is a complex process that involves modifying the transmission housing, fitting custom components, and aligning the drivetrain. Professional installation is highly recommended to ensure safety and optimal performance.

Warranty Conditions

Rebuilt Subaru 5-speed transmissions often come with a one-year (12-month) parts replacement warranty. However, warranties generally do not cover installation costs or issues arising from improper installation. Proper maintenance is crucial to uphold the warranty.

Steps To Upgrade Your Volkswagen

Upgrading your Volkswagen with a rebuilt Subaru 5-speed transmission involves several stages. Here’s a step-by-step overview:

Step 1: Consultation And Planning

Discuss your vehicle’s needs with a reputable manufacturer or supplier. Outline your performance goals, and they’ll help you choose the right final drive ratio, differential type, and additional components.

Step 2: Selecting The Transmission

Choose between 2WD and AWD configurations. For rear-engine Volkswagen, the 2WD option with a shortened nose cone is ideal. For AWD setups, the repositioned rear output cover and flange provide seamless integration.

Step 3: Preparing The Core

If supplying a core, ensure it meets the manufacturer’s requirements for usability. This step is critical to avoid delays and additional charges.

Step 4: Professional Installation

Once you’ve selected your transmission, have it installed by an experienced professional. They’ll ensure all components are correctly aligned, machined, and secured for optimal performance.

Step 5: Testing And Adjustment

After installation, thoroughly test the transmission to verify smooth operation and make any necessary adjustments.

Customization Options: What’s Best For You?

One of the biggest advantages of upgrading to a rebuilt Subaru 5-speed transmission is the ability to customize the setup. Here’s a closer look at the options available:

Final Drive Ratios

• 3.9:1: Best for fuel efficiency and long-distance driving.
• 4.11:1: A balanced option for everyday use with a mix of city and highway driving.

Owning a Volkswagen T3 or Vanagon is a rewarding experience. These classic vans, built between 1983 and 1991 are beloved for their charm, durability, and versatility.

However, with time and wear, critical components like the transmission begin to show signs of aging. For enthusiasts who want to keep their vans running smoothly, a rebuilt 3-speed 090 automatic transmission offers an excellent solution.

We’ll explore the benefits of opting for a rebuilt transmission, what makes the 3-speed 090 transmission special, and how this upgrade can improve your van’s performance and reliability.

Why Choose A Rebuilt 3-Speed 090 Transmission?

When your original transmission starts to slip or fail, a rebuilt option is often the best way to revive your van. A fully rebuilt 3-speed 090 automatic transmission not only restores performance but also extends the life of your vehicle.

Here’s why it’s a smart choice:

• Cost-Effective Solution: A rebuilt transmission offers the same reliability as a new one but at a fraction of the cost.
• Extended Vehicle Life: With a rebuilt transmission, your VW van can run smoothly for many more years.
• Restores Driving Comfort: Say goodbye to jerky shifts and slipping gears—your rebuilt transmission will feel like new.

Understanding The 3-Speed 090 Transmission

The 3-speed 090 automatic transmission was standard in VW T3 and Vanagon models produced between 1983 and 1991. Known for its reliability, this transmission is simple yet effective making it a favourite among enthusiasts.

This transmission includes a stock differential final drive ratio of 4.09:1 providing a good balance between power and efficiency.

However, the beauty of this rebuilt transmission lies in its versatility. You can customize it with aftermarket final drive ratios to better suit your driving needs. Specialised Parts has available ratios include 3.27:1, 3.72:1, and 4.45:1, each offering a different driving experience.

Key Benefits Of Upgrading To A Rebuilt 3-Speed 090 Transmission

Improved Performance With Rebuilt Components

A rebuilt transmission isn’t just a patched-up version of your old one. It undergoes a complete overhaul with all friction plates, bearings, seals, and gaskets replaced. This ensures your transmission functions as smoothly as it did when it first left the factory.

With every critical component restored or replaced, you can expect optimal performance and longevity.

Tailored Final Drive Ratios For A Customized Experience

The stock final drive ratio of 4.09:1 offers a great balance but you may want a different ratio depending on your driving style. For better fuel economy, a 3.27:1 ratio might be the ideal choice.

If you need more torque for hilly terrains or towing, a 4.45:1 ratio would suit you better. With these options, you can tailor your van’s performance to match your lifestyle.

Why Use Aftermarket Limited Slip Differentials?

Installing an aftermarket limited slip differential (LSD) can take your van’s performance to the next level. LSDs distribute power more evenly between the wheels providing better traction on slippery surfaces.

This upgrade is especially beneficial if you frequently drive off-road or in challenging weather conditions. The rebuilt transmission supports several types of LSDs giving you more control over your vehicle’s handling.

Is A Rebuilt Transmission Right For Your VW Van?

If your van’s transmission has seen better days, a rebuilt 3-speed 090 transmission is an excellent option. Here are some signs that it may be time to upgrade:

• Slipping Gears: Your transmission struggles to stay in gear or slips out unexpectedly.
• Hard Shifting: Shifting between gears feels jerky or delayed.
• Leaking Transmission Fluid: You notice transmission fluid leaking under your van.
• Unusual Noises: Grinding or whining noises come from the transmission.

Replacing your old transmission with a rebuilt one will not only solve these issues but also improve your van’s overall performance.

Switching from all-wheel drive (AWD) to two-wheel drive (2WD) is a strategic decision many Volkswagen and Subaru enthusiasts consider. The 5EAT 2WD Conversion Kit makes this transition easy.

By converting Subaru’s advanced 5-speed automatic transmission from AWD to 2WD, you get rid of unnecessary complexity and weight; it improves power delivery and handling.

Whether you’re building a performance-focused Volkswagen or refining a custom mid-engine setup, this kit provides everything you need to get the job done right.

What Is The 5EAT 2WD Conversion Kit?

The 5EAT 2WD Conversion Kit is a specialized product created to modify Subaru’s AWD system, specifically the 5EAT automatic transmission for use as a 2WD transmission in mid-engine vehicles.

This kit includes all the essential parts required for the conversion, such as:

• Large back cover plate with mounting holes

It ensures that the conversion process is smooth and straightforward. No need for extensive modifications or custom parts—this kit has everything you need.

2. Stub Axle Shafts And Axle Flanges

Another critical feature of this kit is the pair of Subaru OEM stub axle shafts and 100mm standard-length axle flanges. These components are designed for perfect compatibility with Subaru parts meaning you won’t have to worry about fitment issues.

Moreover, the OEM quality ensures durability and long-lasting performance making this conversion kit a reliable choice.

3. Mounting Bracket With Bolts

The mounting bracket complete with bolts provides a secure and stable connection between the new components and the transmission. This ensures that your conversion holds up under various driving conditions from daily use to high-performance situations.
