Common symptoms of a transmission fluid leak in the Hilux include:

Red o r brown fluid puddles under the vehicle, especially near the transmission pan o r cooler lines.
Slipping gears, where the transmission struggles to engage properly o r shifts erratically.
Delayed o r rough shifting, making gear changes feel sluggish o r harsh.
Overheating transmission, indicated by a burning smell o r warning lights on the dashboard.
Low transmission fluid levels, leading to poor performance and increased wear on internal components.

Before diagnosing a leak, many owners first notice hesitation in acceleration, fluid stains on the driveway, o r unusual whining noises. Once symptoms appear, checking fluid levels, inspecting seals, gaskets, and cooler lines, and performing routine maintenance can help prevent severe damage.
