SUSPENSION GP-SEAT 1995727 - Caterpillar

Accidental downshifting of the transmission control does not mean immediate shifting of the transmission.If the machine continues to slow, or if the machine is brought to a stop, the transmission will automatically downshift one speed at a time. The transmission always returns to second speed. Move transmission control (6) to the NEUTRAL position if the machine is stopped.Shift Inhibiting
A shift from any speed into NEUTRAL position is inhibited.Normal Shifting
An automatic downshift will occur when the engine speed decreases to approximately 1280 rpm. An automatic upshift will occur when the engine speed increases to approximately 1890 rpm. The shifting of the transmission is determined by the load that is put on the machine.If the ground speed is less than 5 km/h (3 mph) in any forward speed and the transmission control is moved to the REVERSE position, the transmission immediately shifts into the REVERSE position.If the ground speed is more than 8 km/h (5 mph) in any forward speed and the transmission control is moved to the REVERSE position, the transmission will not downshift until the ground speed of the machine has been reduced to 5 km/h (3 mph). When the ground speed is less than 5 km/h (3 mph) in the NEUTRAL position and the transmission control has been moved to the REVERSE position, the transmission immediately shifts to the REVERSE position.Top Gear Control
Top gear control (5) is used to set a limit for upshifts. The engine must be running and the transmission control must be moved to "D" in order for you to select a limit. "D" is the DRIVE position. When the switch is held in the ON position, the actual gear indicator will flash. Next, the actual gear indicator will cycle through the available gears. When the switch is released, the top drive gear will be set to the value on the display. The display will show the top gear for 4 seconds. After the 4 seconds, the display will revert to the actual gear. The maximum gear that is available to the operator will never be greater than the maximum gear that is set by the service personnel. The minimum top gear that is available to the operator is third gear in the forward direction. The transmission will operate with a high gear limit until the machine is turned off or until another gear is selected.Note: When the engine experiences an overspeed condition, the top gear control will allow the transmission to upshift one speed in order to correct the overspeed condition.Transmission Hold Control Activated
When transmission hold control (3) is placed in the ENGAGED position, automatic shifts are inhibited. Automatic downshifts are inhibited unless the engine is in an underspeed condition. The transmission will automatically downshift if the engine rpm drops too low. Underspeed conditions will occur when the engine rpm drops below 1000 rpm. Automatic upshifts are inhibited unless the engine is in an overspeed condition. If the engine speed reaches 2500 rpm, the transmission will automatically upshift.Braking Operation
The braking system consists of
