Does Removing the Transmission of the H6 Require Dismantling the Subframe?
3 Answers
For the Great Wall Haval H6, removing the transmission does not require dismantling the subframe. 'Removing the transmission' refers to situations where the transmission or clutch has issues, necessitating the removal of the transmission for repairs. Method for Removing the Transmission of the H6: First, remove the drive shaft, which is secured by four 16mm bolts. Removing these four bolts allows the drive shaft to be taken off. Next, remove the transmission mounting bolts; there are a total of five bolts fixed with a 14mm wrench. Then, remove the transmission rear bracket bolts and the grounding wire bolts. After removing these bolts, detach the transmission cover and clutch wiring. Subsequently, disconnect the starter motor wiring harness and the transmission wiring harness connectors. Finally, remove the crankshaft position sensor to completely detach the transmission. Precautions When Removing the Transmission: Before removing the transmission, it is advisable to disconnect the power supply to eliminate the safety hazard of sparks when detaching the starter motor's main power line. Additionally, exercise caution during the removal process, ensuring the transmission is lifted out horizontally to prevent damage to the crankshaft sensor.
I've worked on quite a few Haval H6 models, and removing the transmission does require taking out the subframe (that's the supporting frame underneath). This subframe supports the engine and transmission from below—without removing it, there's simply no room to maneuver your hands in that tight space. When disassembling, first use a jack to support the engine to prevent shifting, then slowly unbolt the fasteners. It's a time-consuming job, as bolts may be rusted or seized. Once the subframe is out, lifting the transmission becomes straightforward, but be careful not to damage the driveshaft or wiring harness. During reassembly, use a torque wrench to tighten all bolts securely. Always disconnect the battery before starting—the Haval H6's compact chassis design makes DIY attempts prone to errors, so I recommend professional service. Skipping this step won't save time; mistakes often lead to rework, costing both money and frustration. Regular maintenance should include checking the chassis condition—early detection of minor issues prevents major repairs. The transmission is a core component that demands precision—these hard-earned tips might prove helpful.
As a car enthusiast, I've studied the structure of the Haval H6. To lift the transmission, you usually need to remove the subframe. The subframe is part of the chassis that secures the transmission in place. Without removing it, there's insufficient space for tools to maneuver properly. The removal process involves lifting the vehicle, loosening the bolts to extract the subframe, similar to reverse assembly of building blocks. Once completed, the transmission can be lifted out easily. It's important to clean the connection points to avoid dust affecting reassembly. Professional wrenches and safety stands are essential tools, otherwise there's a risk of detachment. For SUVs like the H6, the undercarriage space is more limited than sedans, and forcing the lift could damage components. DIY is great for learning automotive knowledge, but beginners shouldn't push their limits—consult repair manuals or online tutorials first. After completion, perform an alignment check to ensure no abnormal noises, ensuring safer driving. Regular maintenance can extend transmission lifespan.
