The Power Transfer Unit (P.T.U.) is attached to a modified automatic transaxle case where the right half shaft extension housing would normally be located.
The Power Transfer Unit is sealed from the transaxle and has its own oil sump. The Unit uses SAE 85W-90 gear lubricant and holds 1.15 liters (1.22 quarts).

If the ring gear and pinion, any tapered roller bearings, case, covers, or pinion carrier fail the entire unit must be replaced.
