Complete Manual Transmissions

INFINITI Complete Manual Transmissions

Here at INFINITI Canada, we understand the importance of keeping your manual transmission in good condition. This mechanical gearbox allows direct driver control over gear selection for engaging performance. The G37 coupe and sedan offered manual transmissions favored by driving enthusiasts. When internal damage occurs from worn synchronizers or broken gears, complete transmission replacement often costs less than extensive rebuilding.

How Manual Transmissions Operate

Your manual transmission contains multiple gear pairs with different ratios mounted on parallel input and output shafts. Moving the shift lever slides collar sleeves that lock selected gears to the output shaft. Synchronizer rings match shaft speeds before engagement to prevent grinding. The clutch system disconnects engine power during shifts to prevent transmission damage. Gear oil lubricates internal components and reduces friction between meshing teeth. Each gear ratio is calculated to provide specific engine speed ranges for acceleration, cruising, or maximum speed capability.

What Damages Manual Transmissions

Synchronizer rings wear down from repeated shifting over 100,000 to 150,000 miles, making gear engagement difficult. Bearing failure causes shaft misalignment that damages gear teeth. Shifting without fully disengaging the clutch grinds synchronizers and creates metal particles that accelerate wear. Hard shifts or missed gears can chip or break gear teeth. Gear oil contamination from water or clutch friction material reduces lubrication effectiveness. Salvaged transmissions often have worn synchronizers or damaged shift forks that cause grinding or difficulty selecting gears even after installation.

Determining When Replacement Is Required

Grinding noises during shifts indicate worn synchronizers that can't match shaft speeds properly. Difficulty engaging specific gears suggests internal damage to that gear's synchronizer or shift mechanism. Gear oil leaks reduce internal lubrication and accelerate wear. Genuine INFINITI Canada manual transmissions maintain proper gear ratios and shift quality throughout their service life, while aftermarket units may have incorrect internal components or gear ratios that don't match your vehicle's final drive.
