Q & A

What is the first step in dismantling the transmission as mentioned in the video?

The first step is to open the housing extension or top of the transmission and remove the speedometer switch and other sensors using the appropriate tools, such as a 22 wrench.

Why is it important to remove the brand plaque before dismantling the transmission?

The brand plaque needs to be removed to access the filling or dumping point for oil, which must be done before further dismantling.

What tools are required to begin dismantling the Avanza/Xenia M2S transmission?

Tools needed include a screwdriver, wrenches (12, 14, 24), snap ring hammer, calipers for measuring, and various extension handles.

What precautions should be taken while using a hammer on the transmission parts?

A plastic hammer should be used to avoid damaging the components. It's also recommended to use a rubber or wood block to avoid direct metal contact.

What is the function of the magnets in the transmission system?

The magnets are used to attract and trap dirt and metal particles from the transmission oil, ensuring smoother operation.

Why is it necessary to remove the snap ring during the disassembly?

The snap ring holds the bearing in place to prevent the output shaft from moving forward or backward. It must be removed to proceed with further dismantling.

How does the disassembly process differ for different parts of the transmission?

Each part requires different tools and techniques. For example, the reverse gear is lifted manually, while the output shaft requires special tools to prevent misalignment.

What should be done before removing the reverse gear from the transmission?

Before removing the reverse gear, the retainer plate and bolts holding it in place should be removed, then the gear can be lifted out without the need for special tools.

What is the significance of the interlock mechanism in the transmission?

The interlock mechanism prevents the gears from moving out of sync or improperly engaging. It must be carefully handled during disassembly to ensure proper alignment during reassembly.

What special trick is mentioned in the video for removing the pins and parts from the transmission?

A special trick involves using a skin or wide tool to catch parts when struck with a hammer, preventing them from falling inside the transmission.
