The ______ diverts transmission fluid within the transmission placing drag on the drive train.

• A. Transmission Retarder
• B. Jake Brake
• C. Telma Brake Retarder
• D. ABS Interface

Answer: (A)

Diverting transmission fluid within the transmission to create drag describes a hydraulic braking method built into the transmission itself. A transmission retarder routes oil through a confined braking path in the gearbox, where the fluid’s flow creates resistance. This resistance converts the vehicle’s kinetic energy into heat in the fluid, placing drag on the drivetrain and helping slow the vehicle without relying on the service brakes. The engine brake (Jake Brake) works by modifying engine exhaust flow, not by moving transmission fluid. ABS interface matters for brake-system control but doesn’t generate hydraulic drag in the transmission. Telma Brake Retarder is a specific brand/type of hydraulic retarder, but the question is describing the general function of a transmission retarder, which matches the concept most directly.
