What Are The Most Common Transmission Problems In Harley 5 Speeds?
There are several common issues that can occur with the Harley 5-speed transmission. These issues can range from difficulty shifting gears to strange noises emanating from the transmission. Let’s explore these problems and their respective solutions.
Difficulty Shifting Gears
A frequent problem encountered with Harley Davidson motorcycles, particularly the 5-speed transmission, is difficulty shifting gears, often requiring clutch adjustment or transmission fluid checks. This issue could be attributed to various factors like damaged shift forks or linkages, clutch adjustment problems, or even low transmission fluid.
To troubleshoot, check the clutch adjustment and ensure it’s properly adjusted with sufficient free play. Inspect the shift linkage and shift forks for signs of damage. If necessary, replenish transmission fluid and adjust the clutch cable. However, if you spot any issues with the shift forks, bearings, or linkages, it’s advisable to consult an expert mechanic for replacement.
Clutch Slipping
Clutch slipping, a common issue among Harley Davidson owners, often signals the need for clutch cable adjustments or a look at the transmission fluid level. It occurs when the transmission gears fail to engage properly. Aside from the previously mentioned occurrences, this can also be triggered by a defective clutch, a stretched drive belt, damaged bearings, or inadequate clutch adjustment.
If you encounter this issue, inspect the gears and bearings for any damages or cracks. If they are in good condition, check the drive belt and clutch for any signs of damage. Often, replacing or adjusting the clutch cable will solve the problem. But if it doesn’t, consider replacing the drive belt and lubricating the transmission.

Spontaneous Popping Out Of Gear
Spontaneous popping out of gear in Harley Davidson motorcycles can result from worn mounts, loose linkage, bad shifter bearings, or a weak spring in the shift rail, all of which are critical transmission system components. To troubleshoot, inspect the shift drum and detent mechanism for any signs of damage. Also, check the shift forks and bushings to ensure they are physically intact.
However, addressing these issues often requires the expertise of a mechanic, as these are crucial elements in the transmission system, and any missteps could lead to further damage.
Clunking, Growling, and Other Strange Sounds
A constant growling sound or a clunking noise can be a sign of transmission problems in Harley Davidson motorcycles, particularly with the 5-speed transmission. These sounds often indicate worn or damaged gears and bearings, a faulty primary drive system, or loose transmission mounts.
A thorough inspection of the transmission bearings and gears is required if you hear a constant growling sound. If you notice clunking noises, inspect the transmission mounts, bearings, and gears in both the transmission and the primary drive system. Any excessive noise signals broken gear teeth, necessitating replacement of the gears, shift fork, and shift drum.
