Description
Power Flow (cont'd)
3rd Gear {8. @, or @ position)
1. Hydraulic pressure is applied to the 3rd clutch. Power from the mainshaft 3rd gear is transmitted to the countershaft
3rd gear.
2. Power is transm ifted to the final d rive gear, wh ich d rives the f inal driven gear and the transfer shaft drive gear (4WD).
3, The transfer shaft drive gear drives the transter shaft and the transfer driven gear shaft (4WD).
NOTE:
. Hydraulic pressure is also applied to the 1st clutch, but since the rotation speed of 3rd gear exceeds that of 1st gear,
power from lst gear is cut off at the one-way clutch.
. The illustration shows the 4WD automatic transmission; Dower flow of the 2WD automatic transmission is identical
to the 4WD except for parts related to the transfer assembly.

1. Hydraulic pressure is applied to the 4th clutch, which rotates together with the mainshaft, and the mainshaft 4th gear
rotates,
2. Power is transmitted to the countershaft 4th gear, which drives the countershaft.
3. Power is transm ifted to the f inal d rive gear, which drives the fina I driven gear and the transfer shaft drive gear (4WD).
4. The transfer shaft drive gear drives the transfer shaft and the transfer driven gear shaft {4WD).

E position
1. Hydraulic pressure is switched by the manual valve to the servo valve, which movss the reverse shift fork to the
reverse position, The reverse shift fork engages with the reverse selector, the reverse selector hub, and the counter-
shaft reverse gear.
2. Hydraulic pressure is also applied to the 4th clutch. Power is transmitted from the mainshaft reverse gear via the
reverse idler gear to the countershaft reverse gear.
3. Rotational direction ofthe countershaft reverse gear ischanged viathe reverse idlergear.
4. Power is transmitted to the final drivegear,which drivesthefinal d riven gear a nd the transfer shaft drive gesr (4WD).
5. The transfer shaft drive gear drives the transfer shaft and the transfer driven gear shaft (4WD).
NOTE: The illustration shows the 4WD automatic.transmission; power flow of the 2wD automatic transmission is identical
to the 4WD except for parts related to the transfer assembly.

6. Set a dial indicator on the transfer assembly flange.then measure the transfer gear backlash.
STANDARD: 0.06 - 0.16 mm (0.002 - 0.006 inl
7. lf the measurement is out of standard, remove thetransfer assembly and adjust transfer gear backlash{see page '14-232 thru 14-2491.
8. Check for fluid leaks between the mating faces oftransfer cover A and cover B.
9. lf there is a fluid leak, remove the cover, and reDlacethe O-ring.
'10. Check for fluid leaks between the mating face of thetransfer assembly and transmission.
11. lf there is a fluid l€ak, remove the transf€r assem-bly, and replace the O-ring,
12. Check the transfer oil seal for damage and fluidle8ks.
13, lf oil seal replacement is required. remove the trans-fer assembly, replace the oil seal, and adjust thetotal starting torque (see page 1+232 thtu ]'4-249||.
NOTE: Do not replace the oil seal with the transferassembly on the transmission.
