How Long Does It Take to Replace a Transmission?
2 Answers
There is no fixed time for replacing a transmission, as it depends on the method of replacement. Below is relevant information about transmissions: 1. Main Functions: To change the transmission ratio, expand the range of torque and speed variations of the driving wheels to adapt to frequently changing driving conditions, while allowing the engine to operate under favorable conditions. It enables the vehicle to reverse while the engine's rotation direction remains unchanged. By using neutral gear, it interrupts power transmission, allowing the engine to start, shift gears, and facilitating gear changes or power output. 2. Working Principle: Manual transmissions mainly consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.
Last time my car's transmission replacement took a full two days. The actual time mainly depends on several factors. Automatic transmissions are more complex than manual ones, requiring more labor for removal and installation. The technician first needs to remove components like the engine undercover, exhaust system, and drive shaft - just the disassembly can take half a day. Then they must verify the new transmission model compatibility, refill specialized fluids, and perform programming adaptations. Also, the repair shop's scheduling is crucial - I had to book one week in advance to avoid waiting for an available work bay. I recommend confirming whether the quote includes new fluids and seals, as some shops charge extra for these, which can cause delays. The entire process typically takes 24-48 hours for regular sedans when everything goes smoothly.
