Transmission

The source of a transmission leak isn’t always so obvious. Take, for example, a fluid leak that emanates from the interface between the engine and transmission. Is the engine’s rear main seal at fault, or has the transmission’s front pump seal sprung a leak? A little trace dye in the transmission fluid will quickly reveal the culprit. Tracerline® lets you find transmission fluid leaks easily and efficiently with Dye-Lite® All-In-One™ full-spectrum oil-based dye. If you prefer a dye that’s formulated exclusively for transmission leaks, choose TP-3200 Dye-Lite® Application-Specific Dye.
