Analysis of Leakage

Analysis of Leakage
The power transfer unit (PTU) may leak 3 different color fluids, red oil leak for an automatic transmission fluid (ATF) and brown-black gear lube for PTU fluid. The PTU seals prevent these types of fluids from leaking. It is important to note which color of fluid is leaking to conduct the most appropriate service procedure.
