How to Remove the Transmission of Great Wall Haval H6?

Below is the method for removing the transmission of the Great Wall Haval H6: 1. Remove the front subframe; 2. Disconnect the connection between the engine and the transmission; 3. Take off the transmission and proceed with disassembly. Here is some related information about the Great Wall Haval H6: 1. The Great Wall Haval H6 is a 5-door, 5-seat compact SUV with exterior dimensions of 4615mm in length, 1860mm in width, and 1720mm in height, with a wheelbase of 2680mm. 2. It is equipped with a 1.5T turbocharged engine and a 6-speed manual transmission, delivering a maximum power of 110 kW and a maximum torque of 210 Nm. The drivetrain is front-wheel drive, with a MacPherson strut front suspension and a double-wishbone independent rear suspension.
That day at the repair shop, I saw the mechanic dismantle the H6's transmission. First, the whole vehicle had to be lifted, and the negative terminal of the battery disconnected for safety. Then, the air filter box and battery base had to be removed, otherwise there wouldn't be enough space to work. I remember when the half-shaft was pulled out, transmission oil poured all over the ground, so it's essential to have an oil catch pan ready in advance. The clutch slave cylinder and shift cables also need to be detached. The most challenging part was the transmission mount bolts—their position was particularly awkward, requiring an extension bar to reach them. Finally, a jack was used to support the bottom of the transmission, and after removing all surrounding bolts, it could be slowly maneuvered out. The entire process takes at least three hours, and it's not something an average person should attempt lightly. If the transmission gets damaged during disassembly, replacement parts alone can cost over 8,000 yuan.
I previously disassembled the H6's transmission when replacing the clutch kit myself. Essential tools include a 24-piece socket set and a torque wrench. After lifting the front wheels off the ground, first disconnect the driveshaft. In the engine bay, remove the throttle body hose and transmission ground wire. The shift mechanism is connected with three steel cables—remember to photograph their positions for reference. The critical step is separating the mating surface between the transmission and engine; those 12 bolts around the perimeter must be loosened diagonally in three stages. The most frustrating part was the reversing radar wiring harness stuck in the housing groove—pulling it hard will snap the wires. Finally, lifting it requires two people working together—that thing is ridiculously heavy, and I nearly threw out my back. Reinstallation is even more troublesome; aligning the bolt holes took me half an hour. Beginners should just take it to a professional repair shop.
I once asked about removing the transmission at a repair shop. The mechanic said the new H6's transmission is connected to the body computer, and without a matching diagnostic tool, it would trigger fault codes. You have to first disconnect the radiator oil pipe and use a special plug to seal it to prevent oil leakage. The turbocharger pipe also needs to be moved aside, as space is extremely tight. The transmission mount rubber bolts require an impact wrench—ordinary wrenches simply can't loosen them. Halfway through removing the bolts, we found a grounding wire hidden behind the engine, something an inexperienced person would never spot. Finally, installing the new transmission requires adding 4 liters of oil, and the old oil must be properly recycled. After hearing all that, I completely gave up on the idea of doing it myself—it's way too complicated.
