- Wheel chocks
- Transmission fluid
- Funnel
- Rags

Safety First
Before you begin, it’s important to take some safety precautions. Make sure you’re working in a well-ventilated area, and wear safety glasses to protect your eyes from any flying debris. Also, be sure to chock the wheels of your car to prevent it from rolling while you’re working.
Step 1: Remove the Transmission
The first step is to remove the transmission from the car. This can be a challenging task, so it’s important to take your time and follow the instructions carefully. Here’s a general overview of the steps involved:
- Park the car on a level surface and engage the parking brake.
- Raise the front of the car using a floor jack and jack stands.
- Remove the wheels.
- Disconnect the negative battery terminal.
- Disconnect the clutch cable or hydraulic line.
- Remove the starter.
- Remove the transmission mount.
- Carefully lower the transmission.
Step 2: Inspect the Transmission
Once the transmission is out of the car, take a close look at it for any signs of damage. Check the case for cracks or leaks, and inspect the gears for any wear or damage. If you find any damage, you’ll need to replace the transmission.
Step 3: Test the Transmission
To test the transmission, you’ll need to set it up on a bench or stand. Once it’s set up, follow these steps:
- Fill the transmission with fluid.
- Connect a power source to the transmission.
- Shift the transmission through all of the gears.
- Listen for any unusual noises or vibrations.
If the transmission shifts smoothly and quietly, it’s probably in good condition. However, if you hear any unusual noises or vibrations, you may need to replace the transmission.
Step 4: Reinstall the Transmission
If the transmission tests out okay, you can reinstall it in the car. Follow the steps in reverse order to reinstall the transmission. Once the transmission is installed, you can reconnect the battery and start the car. Test the transmission by driving the car around the block.
Conclusion
Testing a manual transmission out of the car can be a challenging task, but it’s important to make sure that the transmission is in good condition before you install it in your car. By following these steps, you can test the transmission and make sure that it’s in good working order.
