Hard Gear Shifting
4 Causes of Hard Gear Shifting in Manual Transmissions
Difficulty shifting gears is a common problem in manual transmissions. The main causes are:
- Worn synchronizers – Over time, the contact surfaces of synchronizers and the conical surfaces of gears wear down. This causes resistance when shifting. Using a XADO Revitalizant helps restore friction surfaces and prevent further wear if damage is not severe. Recommended products:
- Worn or broken gear shifting fork – If the fork is damaged, the only solution is to replace the worn parts.
- Incorrect adjustment of the gear shifting mechanism – Proper adjustment is required to ensure smooth gear changes.
- Incorrect adjustment of the clutch linkage – Misadjusted clutch linkage can cause difficulty engaging gears. Adjusting the linkage usually resolves the issue.

How XADO Solutions Help
Applying XADO metal conditioners to manual transmissions reduces noise, vibration, and even fuel consumption.
Atomic Metal Conditioner Maximum Transmission with 1 Stage Revitalizant is a second‑generation, two‑component product designed to restore manual transmission systems. It reduces friction, repairs worn metal in gearboxes, transfer cases, and differentials, and prevents future wear by forming a protective coating. It can be used in mechanical, robotised, sequential gearboxes, including Direct Shift systems. One treatment lasts up to 60,000 miles, extending the lifespan of the transmission and helping avoid costly repairs.
Application
Add the product into the oil filler neck of the transmission, transfer case, or axle gearbox while warmed to operating temperature. Drive for about 5 minutes to dissolve the compound in the oil, then continue driving normally.
Note
Do not use the treatment on completely worn assemblies. The product can be added to any type of oil for manual transmissions. Revitalization is complete after approximately 600 miles, so avoid changing oil during this period.
