Transfer Case

Transfer Case
The transfer case is a gearbox that attaches to the transaxle. On automatic transaxle vehicles, the RH halfshaft passes through the transfer case and engages the differential side gear as in normal 4x2 applications. The transfer case directs power to the rear driveshaft through a helical gear spline coupled to the transaxle differential case, a helical gear drop (idler gear), and hypoid/helical ring gear assembly and pinion set.

NOTE: Repair of the transfer case is limited to seals, gaskets, and output flanges on automatic vehicles only. In vehicles equipped with a manual transaxle, or if any of the geared components, bearings, case cover, or internal shafts fail, a new transfer case must be installed.

The transfer case is sealed from the transaxle and has its own oil sump. The transfer case on an automatic transaxle vehicle uses 0.35 liters (12 ounces) of SAE 75W-140 synthetic gear lubricant. The transfer case on a manual transaxle vehicle uses 0.35 liters (12 ounces) of SAE SOW-90 synthetic gear lubricant.
