Issue: Oil leaking between the automatic transmission and transfer case assemblies which in some instances is being misdiagnosed potentially leading to repeat repairs, for example leaks incorrectly being identified as coming from the rear transmission oil seal or oil pan. Oil weeps through the aluminium casing in the rear extension housing of the transmission in the base of the pocket around where the steel D clutch steel tube is embedded.
