4C2-2 SHIFT ON THE FLY SYSTEM

Shift On The Fly System
Outline of Shift on The Fly System
The shift on the fly system switches between 2 wheel
drive (2WD) and 4 wheel drive (4WD) electrically b
y
driver's pressing the 4WD switch (push button type) on
instrument panel.
This system controls below operations.
1.
Shifting the transfer front output gear (Connecting to,
and disconnecting from, front propeller shaft b
y
motor actuator).
2. Retrial of shifting the transfer front output gear.
3. Connecting front wheels to, and disconnecting them
from, the front axles by axle motor actuator.
4. Indicator on instrument panel.
5. 4WD out signal to other Electronic Hydraulic Control
Unit.

REMOVAL AND INSTALLATION
Read this section carefully before performing any removal and installation procedure. This section gives
you important points as well as the order of operation. Be sure that you understand everything in this section before
you begin.


Removal

P1010011
1. Battery
1) Disconnect the battery cable and the grounding cable from the battery terminals.
2) Remove the battery clamp. Take care not to accidentally short the battery with the wrench or some
other tool.
3) Remove the battery.
4) Disconnect the battery cable at the starter motor and the ground cable at the cylinder body.



2. Engine Hood Apply setting marks to the engine hood and the engine
hood hinges before removing the engine hood. This will
facilitate reinstallation of the engine hood to its original
position.



3. Supporting the Vehicle 1) Jack up the vehicle.
2) Place chassis stands at the front and the rear of the vehicle.


4. Under cover (for 4x4 model) 5. Rear propeller shaft 1) Remove the propeller shaft flange yoke at the rear differential.
2) Remove the center bearing retainer bolts.
3) Remove the propeller shaft together with the center bearing from the transmission mainshaft spline.

6A – 38 ENGINE MECHANICAL
6. Front propeller shaft (for 4x4 model)
Remove the spline yoke flange bolt at the transfer output
shaft.
Do not allow the spline yoke to fall away from the front
propeller shaft.
If the spline yoke should fall away from the front propeller
shaft, align the setting marks on the spline yoke and the
propeller shaft to reassemble the two marks. The setting
marks are punched circles approx. 3mm (0.12 in) in
diameter.

7. Clutch slave cylinder (for M/T model)
8. ATF pipe (for A/T model)
9 Shift control cable (for A/T model)
10. Transmission sensor harness
Remove the vehicle speed sensor connector, inhibitor
switch connector (A/T), ATF temperature sensor
connector, back up light switch connector (M/T) from
transmission.
11. Breather hose (for A/T model)
12. Transmission shift lever (for M/T model)
Remove the shift lever from the floor.
13. Transfer shift lever (for 4x4 model)
Remove the shift lever from the floor.

14. Transmission member
1) Support the transmission with the transmission jack.
2) Remove the transmission member mounting bolts
fixing the transmission member to the chassis frame.


15. Torque converter bolt (for A/T model)
1) Remove the under cover under the torque converter
housing.
2) Rotate the flywheel by using tire lever or some other
tool, and then remove the torque converter bolts.
16. Transmission coupling bolt
1) Support the engine with the garage jack.
2) Use the jack to slightly lower the transmission.
3) Remove the transmission coupling bolts.
17. Transmission (and transfer)
Separate the transmission (and transfer) from the
engine.Take care not to damage the transmission, the
engine, and their related parts..
