This imported automatic transmission (gear) filter is a high-quality aftermarket replacement part meticulously engineered for the Toyota Corolla Altis Grande. As a popular and sophisticated automatic sedan on the roads of Pakistan, particularly in Lahore, the Altis Grande’s continuous variable transmission (CVT) or conventional automatic transmission (depending on the model year and variant) relies heavily on impeccably clean transmission fluid to operate smoothly, efficiently, and reliably.
The transmission filter is a crucial component located inside the transmission pan, often submerged in the transmission fluid. Its primary function is to continuously remove harmful contaminants from the transmission fluid as it circulates. These impurities are generated during normal transmission operation and can include:
- Metallic wear particles: Microscopic fragments from the friction of internal transmission components (clutches, gears, bearings).
- Clutch material debris: From the normal wear of clutch packs in automatic transmissions or CVT belts.
- Sludge and varnish: Byproducts of fluid degradation due to heat and oxidation.
