Remove the screws of the drive shaft and lower the drive shaft. Unscrew the transmission oil drain plug, drain the gear oil into a container, and tighten the drain plug after the oil is completely drained. Next, disconnect the reverse light wiring and remove the transmission cover plate inside the cabin. Then, unscrew the ground wire fixing screw and remove the ground wire. After that, release the clutch release fork. Remove the connecting screws between the transmission and the flywheel housing. Finally, unscrew the transmission support plate fixing screws and lift the transmission off the vehicle.

Disassembling a transmission is no small task. I once tried to save money by doing it myself and ended up putting in a lot of effort. It's best to have two people working together. First, lift the car and secure it firmly with support stands—safety is paramount, so don't take it lightly. Then, disconnect the negative terminal of the battery to prevent short circuits and fires, and drain the transmission fluid to avoid spills. Next, remove the wiring and control line connectors, making sure to note their positions to avoid confusion. Support the engine before removing the driveshaft or axle, and finally, unbolt the transmission and carefully maneuver it out. The whole process requires a full set of tools, including wrenches and a jack. Without experience, it's easy to damage seals or sensors, which can lead to costly repairs. I recommend watching online tutorial videos first and assessing your capabilities—don't push yourself too hard. Sometimes, taking it to a professional shop is more hassle-free and efficient.

The steps for dismantling a transmission can be roughly divided into several parts. Based on personal experience, it's essential to prepare tools such as socket wrenches, a support stand, and an oil pan. Start by securely lifting the vehicle to ensure safety, then disconnect the battery cables and drain the transmission oil without causing environmental contamination. Next, remove surrounding components like the exhaust system and provide additional support to the engine to prevent it from sagging or shifting. After that, disconnect the drive shafts, electrical harnesses, and other interfaces, taking care to dismantle them gently without force. Use a mechanical support stand or an assistant to hold the transmission body, and carefully remove it after taking out all the bolts. Remember the size of each bolt to avoid incorrect reassembly, as aligning the components during reinstallation can save a lot of effort. The entire process requires patience and may take several hours. Check the condition of the gearbox—if there's any wear, it can be addressed at the same time. Regular maintenance, such as monitoring fluid changes and detecting issues early, can help avoid this hassle.

Prioritize safety and assess risks before disassembling the transmission. Unstable vehicle support may cause collapse and personal injury, while fluid leaks pose corrosion or fire hazards. DIYers must wear protective gloves and goggles, using dedicated support equipment. First disconnect the battery and properly dispose of drained fluids, then remove connectors to prevent accidental pulling. Professional technicians are recommended due to delicate components being prone to damage - common DIY mistakes include bolt misalignment or oil line rupture. Post-reassembly, conduct comprehensive testing to ensure proper operation and comply with local automotive repair regulations to minimize disputes. Safety oversights carry high costs - caution advised for non-experts.
