Quizplus · Accepted Answer

Technician B is correct because coolant in the transmission fluid often indicates a problem with the oil cooler, which is a common source of such contamination in many types of transmissions, including Allison. Technician A's statement is not entirely accurate because not all metal particles indicate an imminent transmission failure; some amount of fine metallic particles can be normal, especially in a new or recently rebuilt transmission as it wears in.
