Transmission Removal and Installation Method?
3 Answers
Disconnect the universal joint between the transmission and the driveshaft; then remove the clutch housing screws to separate the transmission from the clutch. Clean the oil sludge and dirt on the exterior of the transmission, taking care to protect the front and rear axle heads. Unscrew the oil drain plug to drain all the lubricating oil from the transmission, then reinstall the oil drain plug. The general disassembly sequence is: transmission cover, first shaft, second shaft, intermediate shaft, and reverse gear shaft.
As an experienced driver, I strongly advise against attempting transmission removal and installation yourself. The transmission is awkwardly positioned in the vehicle's undercarriage, requiring complete vehicle lifting for access. Without professional tools or expertise, you risk damaging surrounding components like wiring or cooling lines. Reassembly demands millimeter precision - even slight looseness can cause abnormal noises or unstable driving. My recommendation: leave it to authorized dealerships or certified repair shops with proper equipment and trained technicians. Pro tip: regular transmission fluid changes can prevent major overhauls - don't wait until problems arise. Remember: safety first. DIY attempts to save money might backfire, potentially doubling repair costs if mistakes occur.
Regarding how to disassemble and install a transmission, I've learned some from car forums, but it's super complicated in practice. The basic process is: first disconnect the car battery to prevent short circuits, then loosen the connecting bolts and wire connectors, and slowly separate the transmission from the engine. However, each car model has a different structure. Some manual transmissions are easier, while automatic ones require extra caution with sensors and such. You need a complete set of tools for disassembly, like jacks and wrench sets, but where would ordinary people keep these at home? The most critical part is precise alignment during reassembly, otherwise the car may vibrate or malfunction when driven. I advise everyone not to attempt this lightly, because a mistake could potentially damage the entire engine. If you really want to learn, start with simple tasks like changing the oil to gain experience before tackling bigger challenges.
