Final answer:
The correct answer is option C) Both A and B.Both Technician A, suggesting a leak-stopping additive, and Technician B, recommending RTV sealant, are correct as they offer short-term solutions to an automatic transmission's mild fluid leak.
Step-by-step explanation:
The correct answer is option C: Both A and B. Technician A suggests using a leak-stopping additive, which is a common and sometimes temporary solution for minor leaks. These additives can swell gaskets and seals slightly to stop or slow the leak. Technician B recommends using RTV sealant, which stands for Room-Temperature-Vulcanizing sealant, at the leak area.
RTV sealants are often used for gasket creation and can be used as a supplemental sealant to repair minor leaks. In the case of a mild fluid leak at the pan gasket, either method may provide a short-term solution. However, it is highly recommended to address the root cause and replace the gasket or properly reseal the pan to ensure a long-term fix and prevent potential future damage to the transmission.
