The synchronizer makes me recall a discussion concerning “double clutching” and whether or not you need to use this method of shifting with the T-84J. First, off, what the heck is meant by, and how do you “double clutch”? Double Clutching, was a prescribed feature of Army driver training. The “purpose of double clutching is to synchronize the speed of the flywheel and the turning clutch disks so that gear shifting may be accomplished with a minimum of clashing of gears.” The procedure?
- Depress clutch pedal
- Move gearshift lever to neutral position
- Release clutch and at the same time depress the accelerator until the engine speeds up and the gear speeds are more nearly synchronized.
- Depress clutch pedal again move gear-shift lever to the next lower position.
- Release clutch pedal and at the same time accelerate engine to obtain desired road speed.
