Manual Transmission Synchronizer Replacement Cost

The cost of replacing a manual transmission synchronizer will vary greatly depending on the make and model of the vehicle, as well as any additional parts that may need to be replaced. On average, it can cost between $500 and $1000 for labor costs alone. Additionally, if the part itself needs to be replaced then this can add significantly more onto the total price.

Generally speaking, it is best to speak with an experienced mechanic or auto shop before making any decisions in order to get a better idea of what specifically needs to be done and how much it will cost.

Replacing a manual transmission synchronizer in your vehicle can be expensive, with costs ranging anywhere from $800 to $1400. The cost of replacing the synchronizers depends on the make and model of your car as well as labor rates and parts availability. It is important to have this repair done by an experienced mechanic so that you can rest assured that the job is being done correctly and safely.

3Rd Gear Synchro Replacement Cost

Replacing the 3rd gear synchro in a manual transmission can cost anywhere from $100 to over $500 depending on the make and model of the car. The labor costs associated with replacing the synchro are typically higher than those for other parts, so it is important to consult with a professional mechanic before attempting any repairs yourself. Additionally, some vehicles may require special tools or expertise that not all mechanics possess, further increasing repair costs.

2Nd Gear Synchro Replacement Cost

Replacing a 2nd gear synchro can be an expensive repair. Depending on the make and model of your vehicle, it could cost anywhere from $500-$1200 to replace the damaged part. It’s important to remember that this is just for parts – labor costs will vary depending on where you take your car for repairs.

Additionally, if other components are affected by the damage (such as bearings or gears) then those costs must also be taken into account when considering how much you’ll need to pay in total for the repair.

Manual Transmission Synchronizer Symptoms

When the synchronizer in a manual transmission isn’t functioning properly, it can cause shifting difficulties and other symptoms. Common signs of a malfunctioning synchronizer include grinding noises while shifting gears, difficulty engaging certain gears, and “popping out” of gear when driving. It’s important to address any issues with your manual transmission synchronizer as soon as possible to prevent further damage.

How Hard is It to Replace Synchros in a Transmission

Replacing the synchros in a manual transmission can be an arduous task, especially if you lack experience with auto repair. The job requires a good understanding of mechanical systems and often involves removing the entire transmission from the vehicle to complete. If done properly, replacing synchros should take between 6-8 hours depending on the complexity of your particular transmission.

It is important to be aware that some transmissions are more difficult than others and may require additional time or specialized tools for proper installation.

How Do Synchros Get Damaged?

Synchros can get damaged by a variety of factors, ranging from improper installation to excessive wear due to long-term use. Poor lubrication or inadequate sealing can also cause premature synchro failure. In addition, overheating caused by faulty cooling systems or prolonged exposure to high temperatures can damage the internal components and cause them to malfunction.

Damage may also be caused by foreign objects such as dirt, debris, and metal particles that enter the transmission during operation. Finally, an improperly adjusted cable linkage system could put too much strain on the synchros which would lead to their eventual breakdown.

How Much Does It Cost to Change a Syncro?

The cost to change a syncro will depend on the specific car model and make. Generally, it is recommended that you take your vehicle to a professional mechanic for this service. Depending on the complexity of the repair and what parts need to be replaced, costs can range from $400 – $1,000 USD or more.

Additionally, labor costs will vary depending on where you have the work done. The best way to get an accurate estimate is by taking your vehicle in for an inspection and having a quote prepared by a professional automotive technician.

What are the Symptoms of Bad Synchronizers in Manual Transmission?

Symptoms of bad synchronizers in manual transmissions may include difficulty shifting gears, grinding noises when shifting gears, jerking motions while attempting to shift and increased difficulty engaging the clutch. Other symptoms can include delayed engagement of the clutch pedal or a sensation that it is not pushing back against your foot as expected. In some cases, these problems can be caused by worn-out or damaged parts within the transmission itself and require professional repair.

Is It Cheaper to Rebuild Or Replace a Transmission?

When considering the cost of rebuilding or replacing a transmission, it is important to consider factors like the make and model of car, labor costs, and parts availability. Generally speaking, rebuilding a transmission can be cheaper than replacing one since you are only paying for labor. However, if your car requires rare or hard-to-find parts in order to rebuild the transmission then it may be more cost effective to replace it with an entirely new unit instead.

Additionally, if there is significant damage to the transmission that cannot be easily repaired then replacement will likely be necessary regardless of part availability or price. Ultimately, whether rebuilding or replacing a transmission is cheaper depends on numerous factors specific to each individual situation.


From this blog post, it is clear that replacing a manual transmission synchronizer can be an expensive and complex process. Depending on the make and model of the vehicle, parts may need to be ordered from specific dealerships or specialty shops. Labor costs also vary depending on the complexity of the work involved in performing a replacement.

However, with proper maintenance and regular inspections, manual transmission synchronizers should last for many years and provide smooth shifting performance.
