Issue
During manufacturing, improper straightening of the countershaft after heat treatment left microscopic cracks in some shafts. Repeated aggressive downshifts at high speed cause these cracks to propagate until the shaft fractures, rendering the vehicle inoperable. In the worst case, the rear wheels may lock.
Corrective action
On all vehicles, replace the countershaft with a non-defective unit, or replace the entire engine assembly fitted with a non-defective countershaft.
