Car won't go into gear

Symptoms

• Shifter moves but nothing engages
• Grinding when trying to shift
• Works in some gears but not others
• Engine revs but the car doesn't move

Likely causes

• CommonLow or old transmission fluidLow fluid starves the hydraulic pressure needed to engage gears.
• CommonWorn shift cable or linkageA stretched or disconnected cable stops the selector from moving internal gears even though the lever moves.
• PossibleClutch not releasing fully (manual)A worn clutch disc or bad hydraulics can leave the clutch partially engaged.
• PossibleFailing shift solenoid (automatic)Solenoids direct fluid to engage specific gears; a stuck one blocks that gear.
• Less commonInternal transmission wear or damageWorn clutch packs or gear teeth can prevent engagement entirely.

What to do

1. Park on level ground and, with the engine warm and running, check the transmission fluid level and color if your vehicle has a dipstick.
2. Note whether the problem happens in every gear or only one or two.
3. On a manual, check that the clutch pedal has normal free play and presses fully to the floor.
4. Check that the shifter or console linkage moves through its full range without binding.
5. Look for a transmission or check-engine warning light, which points to an electronic fault.
6. If fluid is low, top off with the type listed in the owner's manual and try shifting again.
7. If fluid is dark, smells burnt, or the problem continues after topping off, stop driving it and arrange a tow rather than risk more damage.

Tools and parts

• Dipstick or fluid level tool (if equipped)
• Flashlight
• Rags

When to call a pro

See a transmission specialist if fluid is fine and the car still won't shift, or if fluid looks burnt or metallic, since that points to internal wear a shop needs to diagnose.
