2. This means a replacement used automatic gearbox.
Having said that, Start with a good service of the existing unit, Toyota mak'em tough.l Besides, We don't go replacing gear boxes just because we don't have anything better to do on a Sunday afternoon.
ATF stands for Automatic Transmission Fluid . for your car it's a red colored fluid looking like cough syrup AKA the life blood of the gear box. Recommend a place specializing on Auto boxes for a good service.-*Ref previous posts
Remember, Maintenance is cheaper than Repair/replacement.
Ah, Do you have any idea of it's maintenance history? as the 2C engine is having a timing belt and must be replaced every 100 000km with genuine stuff. And if the car was maintained at Daragarage, you can be guaranteed that it's a cheap knock off and will last less than thee recommended mileage
Cheers..
