OEM Nissan Complete Manual Transmissions

Control Gears with Complete Manual Transmissions

You can trust Nissan Canada to always have the parts you need at a great price. Complete manual transmissions include gearsets, synchronizers, shafts, and housings. These mechanical assemblies provide driver-selected gear ratios. Factory transmissions use precise machining for smooth shifts and quiet operation. Durable construction ensures reliable power transfer.

How Manual Transmissions Change Gears

Your manual transmission uses constant-mesh gears on parallel shafts. Synchronizers match gear speeds before engagement preventing grinding. The shift linkage moves selector forks that slide synchronizer sleeves. Dog teeth on synchronizers lock gears to output shafts. The clutch disengages engine power during shifts. Input shaft connects to the clutch disc. Output shaft delivers power to the differential. Nissan manual transmissions for vehicles like the Versa and Frontier include specific gear ratios for performance and economy. Bearings support rotating shafts. Shift detents hold gears in position. Oil lubricates all moving parts. The transmission bolts to the engine and works with clutches and parts for complete operation.

What Wears Out Manual Transmissions

Manual transmissions develop worn synchronizers from aggressive shifting. Bearings fail from inadequate lubrication or contamination. Gear teeth chip from missed shifts or shock loads. Shift fork wear creates sloppy gear selection. Seals leak allowing oil loss. Generic aftermarket transmissions lack proper quality control. Improper clutch adjustment causes incomplete disengagement and grinding. Contaminated oil accelerates wear on all components. Input shaft splines wear from clutch disc contact. Shift linkage bushings deteriorate affecting shift feel. Extreme use overheats oil breaking down lubrication properties.

Identifying Transmission Problems

Replace complete manual transmissions when multiple gears grind during shifts. Difficulty engaging gears indicates worn synchronizers. Most manual transmissions last 150,000 to 200,000 miles. Jumping out of gear suggests worn detents or shift forks. Grinding noises in neutral point to bearing failure. Gear oil leaks create spots under the vehicle. Hard shifting requires investigation of clutch and transmission. Whining noises change with vehicle speed indicating internal wear. Metal particles in drained oil suggest internal damage. Genuine Nissan complete manual transmissions include properly machined gears and correct bearing specifications that ensure smooth shifting and long life, unlike remanufactured transmissions that may have worn synchronizers or incorrect gear spacing causing shift problems.
