Back to Basics - What is Wrong With Your Transmission?

Won’t Stay in Gear

If you go to shift your car, or simply press the pedal but it will not move, then you may have low transmission fuel. So how does an automatic transmission work? This problem in an automatic transmission can be due to a leak, in which then you will need to learn how to fix a transmission leak. It could also be an issue with the shifter cable. In this case, you may need to simply replace a part on the transmission rather than the entire thing. If you are willing to bring it into a shop, they can link it up to a computer and tell you what is wrong.

Missing Gears While Shifting

If you drive an automatic and your transmission seems to be missing gears, it could be because of a leak, contamination, or even water getting into the transmission. Sometimes this can happen when there is a lot of rain and you have a crack. Although this may not seem like a big deal, it can cause the transmission to overheat. This may have caused serious damage and might be an engine problem. The computer can then not allow the transmission to shift into higher gears.


This condition can show itself as a revving engine as well, but essentially gear slipping is when the gears seem to go back and forth without changing the speed. So how can I fix my transmission from slipping? This is known to be caused by a low level of transmission fluid, contamination, or even wear on the internal parts. Most of the most common sign of this is engine revving. It can also be a sign that your clutch needs to be replaced, or something else inside the transmission is off.

Leaking Fluid

Your vehicle should never be leaking. If you see a leaking red fluid this is a bad sign and it means that you may have a transmission leak. Typically this will come from the cooler lines, a seal may be split or a broken gasket. This can be dangerous because if there is a leak it may cause your car to overheat.

Burning Smell

Any type of smell that is burnt is either the clutch or a leak. This is extremely dangerous! If you can catch this early then you may be able to save the transmission. Otherwise, you may be in for a very unpleasant surprise!

Clunking, Buzzing, Humming

Generally buzzing, clicking, or humming is coming from within the transmission and may be gear damage, or another problem within it. Buzzing can also be a poorly sealed surface or low transmission fluid.

No Power

If your car has no energy, but the engine works, it means that there may be an issue with the internal workings of the transmission. In this case, the computer in the vehicle may be limiting power because of another problem. It does this to protect itself, but you may need to have the codes ran to figure out what the problem is.

Check Engine Light

The check engine light relates to the entire car, and it can show you if you have trouble with other areas of your car as well. Despite this, overheating, problems with sensors, a slipping transmission, and other problems will show up on here. There is not a transmission slipping quick fix, but you should try to see which systems and circuits are displaying the issue, and then you can decide what you plan to do.

Manual Transmission

Issues If you choose to drive a manual transmission then you may notice a few extra issues as compared to an automatic transmission. The first is that your gears might grind while shifting. This is usually related to the clutch, and the rings inside of it. When these rings are worn down it can cause this problem.

Another issue that occurs in manual transmissions is that the clutch pedal may grab too high or too low. This is usually an issue with the hydraulic system. If the clutch pedal grabs too high, you can easily adjust this to fix the issue.

You might see obviously broken parts, dirt, objects, or out-of-place issues. Be sure to have a place for each part, and to clean them properly.

Step 4: Reassembling the Transmission

Reassembling your transmission is the hardest and most important part of rebuilding it. Even if the parts are all in working order, they cannot function if not put together properly. If you were organized and labeled your parts, then this will be evident at this point.

Every piece of your transmission has a spot and should go to the right place. After you have assembled the transmission, you will need to conduct tests as well. If you have any doubts, you should speak to a mechanic before trying to drive your vehicle because it could cause serious trouble.
