Eado's transmission is from Aisin, a world-renowned automotive automatic transmission specialist established in 1969. Aisin holds the global market leadership in automotive automatic transmissions. The Changan Eado offers three transmission options: a 5-speed manual transmission, a 6-speed automatic transmission (AT), and a 7-speed dual-clutch transmission (DCT). Both AT and DCT are common automatic transmissions, but they differ in working principles and structures. The dual-clutch transmission evolved from manual transmissions and shares structural similarities with them. It essentially adds one extra clutch and a gear-shift control mechanism compared to manual transmissions. One clutch controls odd-numbered gears while the other manages even-numbered gears, resulting in high transmission efficiency and rapid gear shifts. For daily use of Changan Eado's transmission, pay attention to the following points: Do not delay transmission fluid changes for extended periods. While many modern vehicles claim to have maintenance-free transmission fluid, this doesn't mean it never needs replacement. Prolonged use of old fluid can damage transmission bearings, housing, and other components. Avoid prolonged coasting in neutral. While some experienced drivers coast in neutral with manual transmissions, this practice can cause automatic transmissions to overheat and may create shocks when shifting back to Drive (D). Never shift into Drive (D) or Reverse (R) before the vehicle comes to a complete stop. Some drivers shift prematurely to demonstrate smooth operation, but this significantly damages transmission gears and may eventually cause gear grinding failures. Avoid frequent steep hill climbs in D mode. Automatic transmissions may overheat under heavy load or upshift too early during steep climbs, resulting in insufficient power. Use manual mode to maintain lower gears or sport mode to protect the transmission in such situations. Do not tow over long distances. When an automatic transmission vehicle breaks down, use a flatbed tow truck with the vehicle in Neutral (N) rather than tow ropes or direct towing by another vehicle.

I've been driving the Yidong for almost two years now. The manual transmission is a 5MT, with exceptionally clear gear shifts, and my left foot doesn't get tired even when clutching in city traffic jams. The newly released automatic versions come in two types: the 1.6L version uses a Japanese Aisin 6AT, smooth as gliding on ice, while the 1.4T version is paired with a 7-speed wet dual-clutch transmission, making acceleration and overtaking swift. The older models once had CVT, but it's mostly phased out now. I'd recommend beginners to go straight for the automatic—the dual-clutch is especially thrilling in sport mode, and the manual mode can simulate downshifting with rev-matching, allowing you to pull half a car length ahead at traffic lights. Remember to change the transmission fluid every 40,000 kilometers; a service at the 4S shop costs just over 300 yuan.

The Eado's transmission setup is quite interesting. The manual version features a traditional 5-speed configuration with short shift throws, delivering a mechanical feel. The automatic options vary by engine: the 1.6L pairs with Aisin's third-generation 6AT, renowned for its reliability; while the Blue Whale 1.4T comes with Changan's in-house developed 7-speed wet dual-clutch transmission, boasting a 94.3% transmission efficiency. Compared to joint-venture cars in the same price range, this wet dual-clutch proves more durable than dry versions, with enlarged cooling fins ensuring smooth performance even during continuous uphill climbs in Chongqing's 40°C heat. Southern owners might prefer the wet dual-clutch, while Northern drivers may opt for the AT's better antifreeze performance. New owners should note: avoid aggressive throttle during the 2,000-km break-in period.

The manual transmission Yidong is equipped with a 5-speed gearbox, and the gear lever offers a comfortable grip without being harsh on the hand. For automatic transmission models: the early 1.6L versions used an imported Aisin 6AT, while the current mainstay is the 1.4T paired with a domestically produced 7DCT wet dual-clutch transmission, boasting high transmission efficiency with urban fuel consumption controlled at around 7L. I noticed that the new model's tuning has been optimized; the occasional jerk when downshifting from third to second gear is now almost imperceptible. It's recommended to opt for the top trim with paddle shifters if the budget allows, as manually downshifting for overtaking feels incredibly satisfying.

The current Yidong model mainly promotes the Blue Whale 1.4T + 7-speed wet dual-clutch transmission. In my actual test, this powertrain combination achieves a 0-100km/h acceleration in just over 9 seconds. The older 1.6L model with a 6AT transmission offers smoother performance but has higher fuel consumption. The new wet dual-clutch performs better in 38% urban congested road conditions, with particularly effective suppression of vibrations during start-stop operations. It's worth noting that the shift cables in manual transmission models require regular inspection, and applying lubricant grease is recommended after three years of use to prevent sticking.

I drove my friend's 2021 Yidong PLUS, and the 1.4T paired with the 7-speed wet dual-clutch transmission is really well-tuned. The shifting rhythm in lower gears is faster than Volkswagen's DQ200, and in Sport mode, it can downshift three gears consecutively. I've disassembled the manual transmission before—the five-speed design is simple and durable, with a double-cone synchronizer design, and the reverse gear has a lockout to prevent accidental engagement. For transmission fluid, I recommend 75W-90 full synthetic, which should be inspected every 30,000 kilometers. The manual suggests replacing it no later than 60,000 kilometers.
