Gears are slipping
I have a manual transmission, and the fourth and fifth gears are slipping.
Experienced mechanics share their insights in answering this question :
Hi there. A common problem with slipping gears in a manual transmission is that your clutch may be becoming weak. Another problem can be that your 4th and 5th gears may need to be rebuilt. I would recommend having a certified technician inspect your gear-slipping issue in order to determine what repairs are needed.

Popping out of gear is a common problem when it comes to manual transmissions. The most common reason a manual transmission would jump out of gear is due to low or contaminated fluid, worn synchronizers inside the transmission, or improperly adjusted shift linkage.
What is the fix for a slipping transmission? It`s simple. Just pop the hood of your vehicle, locate the transmission switch, and change the setting from “SLIP” to “STABLE” . . . If only it were that easy.
A slipping transmission means that it is struggling to shift between gears and/or stay in gear. It could be the sign of a major transmission problem or you may just need minor transmission maintenance.
It is where your transmission slips as you change gears and can be caused if there is not enough fluid present. However, as both automatic and manual transmission systems wear down over time, there is still the possibility that your transmission is worn out.
If you have a manual transmission, a slipping transmission is obvious. You will hear a grinding sound when changing gears and the car either won`t go into gear at all or fall out of gear without warning. Often, your first instinct when your manual transmission slips is that you will need to replace the clutch.
To put it briefly, no you should never drive your vehicle if you believe there to be an issue with your transmission in any case. Once a transmission starts slipping it needs to immediately be repaired. Every time you drive it after you feel your transmission slip, it is a risk.
Transmission slipping can be dangerous, and can easily lead to accidents, or further damage to your transmission. Get your car check out by a mechanic right away if you`re experiencing this issue.
Low fluid levels can cause gears to miss, which will result in a grinding sensation. The occasional slipped gear might seem like a small issue at first, but it`s always a good idea to have the transmission looked at when this occurs to avoid costly repairs in the future.
If your transmission fluid is old, contaminated, and/or too low, it will speed up that wear on tear on your gears. This can cause them to not engage properly, leading to a slipping transmission. Both manual and automatic transmissions require some sort of clutch system that`s integral to changing gears.
A slipping clutch is a common occurrence that will happen at some point with a manual transmission vehicle, it is recommended that a clutch is checked after 60k miles or over.
If your transmission won`t stay in gear, your clutch is to blame. It`s likely that one of two problems is to blame: First of all, your clutch may be worn down. If you have a clutch with a worn disc, flywheel, bearing, or pressure plate, it may be time to replace the clutch. Second, your clutch pedal may be misaligned.
The most common reasons a manual transmission failed are lack of lubrication, incorrect lubrication and improper or no clutch release.
Major transmission repair requires disassembling, inspection, cleaning, and rebuilding. It`s labor intensive and cost prohibitive. Luckily, transmission failure doesn`t usually happen without warning.

My clutch went from a slip in one gear to all 6 gears to sticking to the floor all in under 3 hours of non consecutive driving.
Hi there, thanks for writing in. It’s entirely possible that a component failed. For instance, if the clutch pressure plate failed, then the clutch pedal will feel very spongy and can cause the car to slip and be very difficult to shift. If it has a dampened flywheel, and that fails, then the car may lose the ability to go anywhere. It will go into gear fine, but will not move forward. If a clutch release lever failed, it may no longer release the clutch enough to allow gear changes, though slipping would be minimal. A failing hydraulic component could also cause the clutch to fail very quickly. Based on the symptoms, I think that the pressure plate has failed, but it’s impossible to say for sure without seeing the car in person. You should have a qualified technician, such as one from YourMechanic, inspect your car and diagnose your clutch issue.
My manual car won’t go into gear, it turns on and the clutch goes down perfectly fine. It happened after my gears grinded, the car
If the clutch mechanism is releasing properly, and the shift linkage is not malfunctioning, your transmission will have to be removed from the vehicle and inspected. Once a transmission has been removed from a vehicle, if the problem is a broken or worn part or parts, and the transmission has 100,000 miles or more, the most cost effective approach is to just simply rebuild the whole transmission. There are transmission rebuild kits that are sold just for this purpose. Rebuilding a transmission is no big deal and is indeed easier in many respects than rebuilding an engine. You can rebuild your transmission right in your own garage. You can NOT rebuild an engine in your own garage due to the highly specialized, and extremely costly, machine shop equipment required. Occasionally, mobile mechanics will take on a transmission rebuild job especially as once the mechanic removes the transmission from the vehicle, it is just simply a modular unit that can be easily transported to a mechanic’s shop and rebuilt right there and then returned to your vehicle. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Loose gearbox that won’t find 2nd or 5th gear, sometimes hard to differentiate between 1st and 3rd.
There are a couple of possibilities. The first thing that comes to mind is of course the shifter itself. There is a nylon ball and socket joint at the base of the gearshift lever that sometimes falls apart, making the feel of the shifter very vague. Additionally, there are links to the transmission shift linkage that involve nylon bushings and joints that can fall apart. Both problems are very common on your car. The other less common possibility is that you have a bad motor mount that is allowing the transmission to move around too much when you try to shift gears. either way, it’s not a big deal to fix, and probably won’t require expensive transmission work. If you contact Your Mechanic, they can send a technician to your home or office to check out you shifting issue and let you know what repairs it will take to correct it.
My manual gear box is starting to get a little bit "clunky" as i change gears, is there an additive i can add to the gear oil?
The first thing to do is to drain and check the oil to see if it has any broken chunks of metal or a lot of brass metal pieces that indicate the gears and synchronizers for the gears are bad. If no metal is found then replace oil with recommended oils for transmission. If metal is found then an internal transmission repair is needed.
Gear Shuffling Problem in Vauxhall Vectra 52 Registration
Hi there. We don’t see a lot of Vauxhall Vectra’s here in the United States, so unfortunately, we’re not able to suggest a possible solution or cause of this problem you’re experiencing. You should consult with a professional mechanic in your home town to determine what’s causing the shifting problem you’re experiencing.
Sifter floats from gear to gear and when letting out the clutch there is no response.
Hi there. Either the clutch has failed causing the transmission not to engage in any gear, or the transmission shifter plastic rings broke and will not engage the shifter. Check the clutch and make sure that it is moving when the pedal is pressed down. If the fork on the bell housing is moving and the wheels can be moved when the clutch pedal is depressed and then the wheels not moving when the pedal is let up, then the clutch should be in an okay shape. Most likely the plastic rings on the shifter housing has broke and making the shifter move around. If you need further assistance with the shifter moving around too much, then seek out a professional, such as one from YourMechanic, to help you.
Second gear misshifts when I drive, all other gears are fine.
A transmission coming out of gear is most often caused by worn transmission components. It may be possible that the synchronizer rings, which are meant to smoothly mesh the gears inside of the transmission, have worn out and are no longer able to stay in gear.
It may also be possible that the gears themselves have worn out, and can no longer hold the torque of the engine. This is usually preceded or accompanied by a grinding noise when attempting to shift into that gear. If this is the case, it may be possible that the transmission may need to be rebuilt.
As transmission rebuilds can be expensive, I would recommend having the vehicle diagnosed by a professional technician who specializes in transmission, to determine if a rebuild is required.
My truck won’t allow me to change gears even when pressing the clutch. No gears go in at all. Makes it impossible to drive.
Hello, this concern is possibly the slave or clutch master cylinder failure. These two components use brake fluid to apply pressure for movement of the clutch system. This fluid breaks down in time and causes the seals to fail (leak). A low fluid level would cause this concern as well as internal leakage. Replacement of components would be necessary. This type of concern would need to be inspected. If you’d like, a certified technician from YourMechanic can come to your location to diagnose your vehicle, and possibly replace your clutch master cylinder if need be.
