Answer:
Technician B is Correct
Step-by-step explanation:
The correct answer from the question is B because it is mandatory for the transmission cooler to be flushed and thoroughly checked to ensure there is proper flow whenever the automatic transmission unit is to be replaced or even rebuilt. This is to ensure that the fluid in the transaxle is properly cooled so that any form of harm can be prevented. On the other hand, Technician A is wrong in his opinion because it is not mandatory to replace the steel plates even if the friction discs is to be replaced during an overhaul.
