Question

Technician A is correct as it is standard practice to use new gaskets and seals and lubricate parts when assembling a transmission, especially a valve body. This ensures proper sealing and reduces the risk of leaks.

Technician B is not correct as increasing torque on reused bolts and fasteners can actually result in over-tightening, causing damage to the threads or the parts being fastened. The correct practice when reusing fasteners is to follow the manufacturer's recommended torque specification, taking into account any procedures for lubrication or use of thread-locking compound.
