Jumps Out of Gear

Transmission Jumps Out of Gear





Test 1-14

Diagnostic Aids
You should perform a static shift and a dynamic shift test. The manual transmission can have a number of problems to make it jump out of gear. Some of the most common ones are misalignment of the transmission to engine, the clutch housing loose, or misalignment. The transmission should also be checked for worn or damaged input bushing to flywheel or worn or damaged input and output shaft bearings. An bent input shaft could also be the result of the transmission jumping out of gear. When going into the internal part of the transmission also check for worn detent springs, synchronizers, worn teeth on the gears or even worn thrust washers.
When doing inspections of the manual transmission you should inspect all internal parts for worn or damaged parts.
