Why is my manual transmission grinding when shifting? Transmission is very complex parts that is why when there is trouble it is very hard to diagnose without looking at the actual transmission, the diagnosis mention on this article is just a possibility unless the actual transmission is inspected.


Noise When Shifting into Two or More Gears

Conditions when car trouble occurs
While driving and about to shift into two or more gears you will hear a noise coming from the transmission.

Transmission Popping out of 3rd Gear and High Gear

Conditions when car trouble occurs
When shifting into the 3rd gear or in a high gear in particular, the transmission pops out. However the transmission shifts normal in other gears.

Possible cause of car trouble
1. The shift linkage is faulty.
2. The shaft movement is excessive

Troubleshooting car trouble
Because the transmission is very complex parts when it comes to vehicle, it is very difficult to explain in detail what is going on in the transmission why the transmission is popping out of the 3rd gear or the higher gear in particular when the shift linkage is at fault or when the shaft movement is excessive. Just a simple explanation is that the shift linkage and the degree of input shaft play has something to do of having the transmission staying on the gear particularly on the 3rd gear or higher. With that said if one of these components has a problem like out of adjustments or has excessive movement then it can cause the transmission to jump out of a certain gear such as the 3rd or higher gear. All the causes mentioned above is just a possibilities of why the problem occurs and there might be other cause in which can only be determined when the transmission is inspected in actual condition.

Transmission Popping out of 2nd Gear

Conditions when car trouble occurs
When shifting into the 2nd gear, the transmission pops out. However the transmission shifts normal in other gears.

Possible cause of car trouble
1. The shift linkage out of adjustments.
2. The shifter fork is loose.

Because the transmission is very complex parts when it comes to vehicle, it is very difficult to explain in detail what is going on in the transmission why the transmission is popping out of the 2nd gear when the shift linkage is out of adjustments or when the shifter fork is loose. Just a simple explanation is that the shifter fork and the shift linkage have something to do of having the transmission staying on the gear. With that said if one of these components has a problem like out of adjustments or loose then it can cause the transmission to jump out of a certain gear. All the causes mentioned above is just a possibilities of why the problem occurs and there might be other cause in which can only be determined when the transmission is inspected in actual condition.

What to do when the transmission pops out of 2nd gear

Noise when Moving in One Particular Gear

Conditions when the car trouble occurs.
Noise is heard when shifting into one particular gear, the noise do not occur on other gears when shifting.

Possible reasons of car trouble
1. The teeth of the involve gear is damage
2. The bearings of the involve gear is damage

Troubleshooting noise problem when moving in one particular gear
When there is noise problem that occurs when shifting in one particular gear it means that there is a problem on the gear specifically the involve gear when shifting. This kind of problem is commonly cause by a problem of damage gear teeth of the involve gear or a problem of damage bearings for that particular gear.

Clutch Pedal Vibrates When Depressed

Conditions when the car trouble occurs
While the clutch pedal is depressed the clutch pedal vibrates.

Possible cause of car trouble
Loose clutch disc
Loose pressure plate
Loose flywheel

Car problem troubleshooting
In determining this kind of problem, the transmission assemble is need to be open-up since it is very difficult to determine the real cause of the problem, however the usual cause if the clutch pedal vibrates when the pedal is depress is a loose clutch disc, pressure plate, or flywheel. These three components are somewhat connected to each other.

Transmission Jump Out of Gear When Reversing

Conditions when the car trouble occurs
Transmission jump out of gear when the car is reversing. The gear wont stay when backing up.

Possible cause of transmission that jump out of gear when reversing
The shift linkage is faulty
The shift linkage is weak
The shift rail spring tension is weak

Troubleshooting transmission that jump out of gear
Transmission is very complex part and is very difficult to diagnose the cause of the problem when it occur especially the manual transmission.
With regards to the transmission problem when the transmission jumps out of gear during reversing usually the problem that involves is the shift linkage or the shift rail. Those two parts can cause the transmission to pop out of gear if both are faulty or out of adjustments or when the tension of the shift rail spring is weak. There are other possibilities but it can only be determined if the actual transmission is opened up and inspected by a mechanic specialized in transmission repair.

Howling Noise When Clutch Pedal is Release

Conditions when car trouble occurs
When the clutch pedal is release there is a howling noise than can be heard coming from the transmission.

Grinding Noise when Shifting

When shifting into one particular forward gear grinding noise occur. However, the grinding sound is not heard when shifting into reverse gear.


Grinding Sound When Shifting into Reverse Gear

When shifting into reverse gear a grinding sound is heard.


Possible Cause of Grinding Sound when Shifting into Reverse 

The clutch is not disengaging

This kind of problem usually indicates that the clutch is not releasing fully. As you may already know when the driver changes gear the clutch is depressed so that the engine will disconnect from the transmission this is what the clutch do.
