Experiencing difficulty shifting gears in your car can be frustrating and concerning. If you’re gears are sticking, it could indicate several underlying issues that may need attention.
Here are five common reasons why your gearbox might feel like it’s sticking, along with tips on how to diagnose the problem.
1. Low or Contaminated Transmission Fluid
3. Faulty Shift Linkage or Cables
5. Software Issues in Automatic Transmissions

Gears Sticking? Why + What To Do
1. Low or Contaminated Transmission Fluid
One of the primary reasons for a sticking gearbox is low or contaminated transmission fluid.
This fluid lubricates the moving parts within the gearbox, allowing for smooth gear shifts.
If the fluid level is low, or if it’s dirty and contaminated, it can hinder the proper function of the gearbox.
Diagnosis:
Check the transmission fluid level using the dipstick. If it’s low, top it off with the appropriate fluid.
Look for a burnt smell or dark coloration in the fluid, which indicates contamination. If the fluid is dirty, consider a transmission fluid change.
Transmission fluid lubricates the moving parts within the gearbox, allowing for smooth gear shifts.
2. Worn Clutch Components
For manual transmissions, worn clutch components can lead to difficulty in shifting gears.
Over time, the clutch disc, pressure plate, or release bearing can wear down, causing incomplete disengagement of the gears.
Diagnosis:
Pay attention to the clutch pedal. If it feels spongy or doesn’t engage/disengage smoothly, it may indicate a problem.
If the car struggles to shift into gear, especially when the clutch pedal is fully pressed, it’s likely time to inspect or replace the clutch components.
3. Faulty Shift Linkage or Cables
The shift linkage or cables connect the gear lever to the transmission. If these components become misaligned, worn, or damaged, they can cause the gears to stick and create difficulty when shifting.
Diagnosis:
Inspect the shift linkage and cables for any visible signs of wear, fraying, or damage.
Shift into different gears while observing the linkage to see if there’s any resistance or misalignment.
4. Transmission Wear and Tear
Over time, internal components of the transmission can wear down, leading to shifting problems. Worn gears, synchronizers, or bearings can cause gears to stick or grind during shifts.
Diagnosis:
Listen for unusual noises, such as grinding or clunking, when shifting gears.
If you notice slipping or unexpected gear changes, it may indicate internal wear that requires professional evaluation.

5. Software Issues in Automatic Transmissions
Modern automatic transmissions are controlled by complex software. If there’s a glitch or error in the transmission control module (TCM), it can lead to improper gear engagement and shifting problems.
Diagnosis:
Use an OBD-II scanner to check for any error codes related to the transmission.
If error codes are present, a software update or reset may be necessary. Consult with a professional mechanic for assistance.
If you’re experiencing a sticking gearbox, it’s crucial to diagnose the issue promptly to avoid further damage. Whether it’s low fluid, worn components, or software glitches, identifying the problem early can save you time and money in repairs.
If you’re unsure or the issue persists, don’t hesitate to consult with a qualified mechanic for a thorough inspection and professional advice. Safe driving!
