* Shift linkage issues: Problems with the cables, rods, or other parts that connect the shifter to the transmission. These could be broken, bent, disconnected, or improperly adjusted.
* Internal transmission problems: This is more serious and could involve worn gears, a broken shift fork, low transmission fluid, or other internal damage. This often requires professional repair.
* Electrical issues (if automatic): In automatic transmissions, electrical components like solenoids or the transmission control module (TCM) can fail and cause shifting problems.
* Low transmission fluid: Insufficient fluid can cause various problems, including difficulty shifting.
* Valve body issues (automatic): The valve body controls fluid flow within the transmission. Problems here can prevent proper shifting.
