When the unit is locked in one gear, low or contaminated gear oil could cause the problem.
(thanks for answering my first question and been corporative :) )
Oil leaks at the speedometer drive can be caused by loose bolts or bad O-ring, and oil on the speed sensor wiring could cause it malfunction.
SHIfT LINKAGE PROBLEMS, BOTH INTERNAL AND INTERNAL WILL ALSO CAUSE A TRANSMISSION TO LOCK IN A GEAR
STUCK INTERLOCK OR DETENT PINS OR BALLS WILL ALSO PREVENT THE DESENGEMENT OF A GEAR
