Hydraulic pressure is applied to the D inhibitor valve to engage the reverse selector with the third shaft reverse gear while the shift lever is in R.
Hydraulic pressure is applied to the 4th clutch, then the 4th clutch engages the third shaft 4th gear with the third shaft.
Mainshaft rotation is transmitted to the third shaft 4th gear via the mainshaft 4th gear splined with the mainshaft.
Rotation of the third shaft 4th gear is transmitted from the reverse selector hub that rotates with the third shaft to the third shaft reverse gear, via the reverse selector.
The third shaft reverse gear drives the mainshaft 3rd gear via the reverse idler gear.
The mainshaft 3rd gear drives the countershaft 2nd gear splined with the countershaft and the countershaft.
The rotation direction of the countershaft is changed by the reverse idler gear.
With SH-AWD: Power is transmitted from the countershaft to the final drive gear, which in turn drives the final driven gear and the transfer drive gear.
Power is transmitted to the final drive gear, which in turn drives the final driven gear and the differential.
With SH-AWD: As the final driven gear turns the differential assembly, power is transmitted through the transfer drive gear to the transfer output shaft that drives the transfer hypoid drive gear/shaft and the transfer output shaft (hypoid gear).

NOTE: This illustration shows the SH-AWD transfer assembly that is not available on all models.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
