The Toyota Corolla was equipped with the A245E transmission in earlier models. First introduced in 1966, the Toyota Corolla was a no-frills transportation device that was as reliable as death & taxes. In the half-century that followed, over 40 million people bought a Corolla, making it one of the best selling cars of all time. The current Corolla is considerably larger than the original, but it packs more features than the finest luxury car of 1966. It’s also a lot safer, thanks to 8 standard airbags, a high-strength steel body structure, and Toyota’s Star Safety System. A new CVT transmission is also being offered in the E170 Corolla, and they say it’s the most advanced gear-less gearbox to date. Dubbed CVTi-S (Continuously Variable Transmission intelligent-shift), it comes with an ATF warmer to bring the transmission up to temperature faster, reducing harsh operation after a cold start. The transmission pump has also been carefully thought out, and now provides the optimum amount of fluid pressure to avoid drive belt slippage, while using 25% less torque to operate. But on a more interesting note, Toyota gave the new CVTi-S a Sport Mode which creates 7 simulated shift points as you accelerate. A manual gate allows you to change the imaginary gears yourself, and the sporty Corolla S even gets paddle shifters to do the deed. Does something seem wrong with your Corolla? Let’s look at some of the most common Toyota Corolla transmission problems, and see what you can do to get your car back on the road.
