How is the old Mazda 4AT transmission?

The technical highlight of this transmission is the adoption of a flat torque converter (produced by AISIN), which utilizes a multi-plate lock-up clutch to expand the lock-up range. Under NEDC conditions, the lock-up time reaches as high as 89%, improving transmission efficiency and response performance. Below are the relevant details: 1. Structural Principle: Hydraulic automatic transmissions (AT) generally have two structural principles: one is the planetary gear type, which is overwhelmingly common, and the other is the parallel-axis type, a technology exclusive to Honda. The common planetary gear-type transmission evolved to 4AT, and progressing beyond this is considered a technological bottleneck. The difficulty level between manufacturing a 4AT and a 6AT is completely different. 2. Design: The rear of the car features a "four-circle" taillight design typically used only in performance cars, paired with dual single-exit exhausts below, giving the impression that this car is not to be trifled with. The interior of the new car adopts a multi-layered design complemented by a two-tone color scheme. The floating screen also breaks away from the traditional square design. The three-spoke steering wheel is very slender but offers excellent grip. Notably, besides the black interior, a more fashionable white interior is available for the top-tier model.

To be honest, this old Mazda's 4AT transmission feels quite sturdy to drive. I've encountered many owners complaining about its gear-shift jerking issues, especially during stop-and-go city driving—that jerkiness is really unpleasant. But honestly, it's decent in terms of reliability, sturdier than some CVT transmissions from the same era and less prone to major breakdowns. Daily maintenance is much simpler; regular transmission fluid changes can reduce the jerking, and I know some owners with over ten years of use who've kept it running well with this trick. Fuel consumption is admittedly a bit high, possibly exceeding 10L/100km on highways, but with diligent maintenance, at least it won't suddenly fail. As for common issues, seal aging or sensor failures are typical, but this transmission's simple structure makes repairs cheap—it won't break the bank. All in all, it's not a top-tier choice, but its rugged durability deserves praise, making it suitable for owners who prefer hassle-free driving.

When considering buying a used car, I think this old Mazda's 4AT transmission offers good value for money, given its simple structure and low maintenance costs. For beginners, there's no need to worry about outdated technology—the manual mode is generally sufficient, and gear shifts don't hold you back in city commuting. Of course, the downsides lie in fuel consumption and modernity. With fewer gears, it struggles during high-speed acceleration, and daily fuel consumption is about 20% higher than newer 6AT models. But durability is a highlight—I've heard many used car dealers prefer these models because the transmission rarely fails, and it can easily handle another 50,000–60,000 kilometers. For maintenance, it's best to use genuine oil; skimping here isn't worth the risk of early failures. For young buyers, the low purchase price and affordable upkeep are advantages, but those prioritizing fuel efficiency or aggressive driving should think twice.

Having driven similar older Mazda models for over a decade, I find that 4AT transmission quite practical. The gear shifts are generally smooth, with no major issues – occasional minor jerks can be resolved by adjusting the oil pressure. I'd rate its reliability highly as it never left me stranded despite years of use. The fuel consumption is a bit high, but you get used to it after driving for a while – not a big issue as long as you don't race. Daily maintenance like simple oil changes and fluid level checks can be done by myself, saving a lot of money.
