Rebuilding a transmission can seem like a daunting task, but with the right tools, anyone can do it! If you’re looking to rebuild your Subaru transmission, there are a few essential tools you’ll need to get the job done right. In this article, we’ll go over the necessary tools, how to use them effectively, and where to find them.

Understanding the Importance of Quality Tools

Before we dive into the specific tools needed for a complete rebuild of a Subaru transmission, it’s important to understand why using high-quality, reliable tools is essential. Quality tools ensure that the job is done correctly the first time, which prevents costly mistakes and repairs down the line.

Tools Required for a Complete Subaru Transmission Rebuild

Torque Wrench

A torque wrench is a must-have tool when it comes to rebuilding any transmission, and the Subaru transmission is no exception. This tool allows you to tighten bolts to a specific torque value, which ensures that they are tightened to the correct level and won’t loosen over time. For a Subaru transmission rebuild, you’ll need a 1/2" drive torque wrench with a range of 20-200 ft-lbs.

Socket Set

A socket set is another essential tool for a Subaru transmission rebuild. You’ll need a set that includes both standard and metric sizes, as different bolts on the transmission require different sizes. A good quality set will also include both shallow and deep sockets, which will come in handy when dealing with hard-to-reach areas.

Bearing Puller

A bearing puller is a tool used to remove bearings from the transmission. For a Subaru transmission rebuild, you’ll need a puller that can handle various sizes of bearings. There are several types of bearing pullers, including claw-type, slide hammer-type, and hydraulic. Your choice will depend on the types of bearings you’ll be working with and personal preference.

Seal Puller

A seal puller is a tool used to remove seals from the transmission. It’s essential to remove the seals properly without damaging them, as they will need to be reused or replaced during the rebuild process. There are several types of seal pullers on the market, including hook-type, pry bar-type, and slide hammer-type.

Dial Indicator

A dial indicator is a precision measuring tool that measures the runout of the transmission components. It’s used to identify any out-of-spec components that may cause the transmission to fail prematurely. You’ll need a magnetic base holder to attach the dial indicator to, allowing you to take measurements hands-free.

Snap Ring Pliers

Snap ring pliers are a tool used to remove snap rings from the transmission. These rings retain various components in the transmission, including bearings, shafts, and gears. It’s important to have a set of snap ring pliers that can handle different sizes of snap rings.
