6 Causes of Manual Transmission Hard to Shift
A vehicle with manual transmission means the driver needs to manually change the gear by shifting the transmission. The vehicle with this system, no doubt, is economical in terms of fuel and maintenance, but still manual transmission hard to shift issue can occur sometimes in the car.
With this lacking response issue, it mainly points towards the clutch or gear system of the car. So, in order to find the symptoms, it’s important to understand the working of this whole transmission system so that a driver knows what and how to get it fixed.
Most Common Causes Of Manual Transmission Hard To Shift Issue
Transmissions are complicated and constitute many moving parts. However, if a shift is not happening smoothly on the road, then it’s a serious problem and ignoring it for a while can turn it into an expensive transmission repair.
So, here are six major causes explaining why it’s hard to shift gears manual transmission, which can prevent tearing your pocket.
1. The Clutch System
In simple words, the clutch connects the engine of the vehicle to its wheels. And, when you press the clutch with the foot, it disconnects the engine. The driver does this to turn the engine on another speed level while car rolls free. Moreover, when the wheels are not moving and the driver wants the engine to keep turning, the clutch comes into function.
The following parts of this system make it operational:
Clutch Master Cylinder
It’s a hydraulic pump from which fluid is fed to the slave cylinder further down the line in order to finish the amplification if the force applied.
However, if the fluid in the reservoir rises, when the cutch is down, and then rises again when the clutch is released, it means the seal has worn out which has caused internal leaks.
This component transfers the hydraulic pressure achieved through master cylinder, into the mechanical force to control the clutch fork. But when there is an abnormal clutch pedal feel, or low or contaminated brake fluid or, leaks on the floor or engine bay then, these are clearly the symptoms of bad slave or release cylinder.
This part does both, allows and prevent the transmission from the engine. Within this cover, the clutch plate, the pressure plate, and a diaphragm spring spin along with the flywheel which creates inertia in order to engage gears. So, remember to check that the bolts of the clutch cover are not too tight as it may damage the threads or bolt as well.
Release bearing and Fork
These components looses quality due to excessive function and thus, need to be replaced on time in order to avoid unpleasant sounds while using the system. As the result, you may have manual transmission hard to shift.
Its purpose is to connect the vehicle’s engine to the transmission’s input shaft. However, if you feel clutch drag, then either the clutch disc is not working properly or is damaged.
2. Synchronizer Ring
It’s a kind of clutch which allows the components turning at different speeds to synchronize their acceleration and prevent engagement of gears until it synchronizes.
If the teeth of this ring is damaged in some way, it is difficult to shift the transmission.
3. Hub Sleeve
This part of the system connects and brings the main gear into operation with the hub gear. It moves along the direction in which the gear shifts. However, when the hub sleeve is broken or is tightened excessively then, it causes manual transmission hard to shift.
4. Hub Gear
Being a gear ratio changing system, this internal gear acts as a bridge between the gears but it cannot turn freely. This component is mainly between the first and second gear, and behind the third and fourth gear. When the gear damages, it starts causing transmission shifting issue.
- Solving manual transmission hard to shift problem
The gear plays the main role in the manual transmission. With one small, it accepts the hub sleeve engagement with synchronization ring. On the other hand, it’s big teeth, regulates the spinning counter gear when the driver sends the transmission to the output shaft.
The gear doesn’t allow the transmission, if these teeth are not in a proper condition.
6. Less Gear Oil
The poor performance of the vehicle is caused due to the oil in the gear not changed periodically or, is getting leaked. This may produce a grinding or, the squealing sound on changing the gear, which also makes it difficult to operate. So, changing your transmission oil regularly is so vital to prevent gear shift hard to move.
