Low-Reverse Brake & Second Brake
The low-reverse brake operates in 1st and reverse gears, when the vehicle is parked, and during manual operation. It locks the low-reverse annulus gear and overdrive planetary carrier to the case.
The second brake operates in 2nd and 4th gears and locks the reverse sun gear to the case.
The components comprising the low-reverse brake and second brake are as illustrated on the below.
As shown, the discs and plates of the two brakes are arranged on either side of the rear cushion plate, which is itself secured to the case by a snap ring.
