First Speed Of 1 Range
At 1st speed of this range, the low clutch and the low & reverse brake are thrown into engagement. The 1st speed in this range shows the same operation as the 1st speed in the D or 3 range. However, the one-way clutch produces no effect because the low & reverse brake is operated.
The rear internal gear is always interlocked with the transmission case by the engaged low & reverse brake.
During coasting, therefore, the back driving force from the reduction drive gear is transmitted to the input shaft. This means, unlike the 1st speed in D or 3 range, that the engine braking effect is available in this range.
