Air contamination occurs as a result of the rotating gears splashing the liquid inside the chamber. This then can lead to a chemical reaction that creates foam and air bubbles.
Air bubbles or foam in your transmission system will reduce the fluid's lubricating capability as it affects its overall viscosity and some of the gears might end up not getting any lubrication at all. Because of the increased pressure build-up in the transmission system due to overfilling, different components of the transmission system such as the gearbox and lines will also wear out much faster.
If you expose the transmission system to the high pressure for too long, you might even end up having to replace the entire system as it will wear down within a short time. The other consequence of overfilling the transmission system will be a total failure of the system, and this will usually occur when you leave the problem unresolved for an extended period.
Total failure will result from a combination of different things such as leaking seals, grinding metal parts and the pressure build-up. Hence if you ignore the symptoms of an overfilled transmission system discussed below, you can end up spending hundreds of dollars on transmission system replacement. With the potential consequences of overfilling the transmission system above in mind, it should be clear that this is a serious problem that you should not overlook.
And to make sure that you can intervene and resolve it in a good time, here are some of the most common symptoms to look for. But while this might be a simple method as you only need to take out the dipstick and check the level of the fluid, it is not always a reliable one. The transmission fluid will have a thinner consistency when the vehicle is operating at an optimal temperature and turn thick when the temperatures drop. Hence, the dipstick might not provide a very reliable indication.
If you are using this method to diagnose an overfilled transmission system, the right idea would be to first allow the vehicle to run for at least 5 minutes. If you are having difficulties shifting gears, it often means there is an issue with your transmission system.
The transmission filter and fluid would also need flushing and changing. It would take about qt to fill. Starting the engine and letting it run is always ideal for you to get the correct reading.
Always watch out for the cold mark on the stick if the engine is cool. The transmission fluid should be at its upper end. The hot one should be at the upper end of the hot mark. My fluid is way over the line and have only reverse can not go forward, is it cause I have to much fluid?

So you think you might have put too much transmission fluid in your vehicle.
What do you do now? This will prevent from disrupting the oil can, causing an inaccurate measure. Finally, pull out your dipstick. Pro tip: To minimize inaccurate measurements, run your vehicle for minutes before checking your oil. Hard To Shift Gears.
Transmission Fluid Leakage. Wear and Tear Overfilled transmission fluid If you do overfill your transmission, the liquid will gather under your transmission. If you do find transmission fluid It can be relatively easy to determine whether you overfilled or your leak is from wear and tear.
Grinding or Humming Transmission Noises. This includes grinding or humming noises. Engine overheating. Slipping Transmission. Consequences of Overfilling your Transmission. Overheated Transmission.
Here are the two common signs of an overheating transmission: Acrid burning odor Transmission fluids play a crucial role in the system. Slow response times Do you experience a slight delay when you shift the gear? Depleted Oil Quality. Again, put in little fluid at a time to avoid adding too much. If you add too much transmission fluid, you will notice that it may foam, and that can bring about erratic gear shifting.
Some other problems that may arise include oil starvation and transmission damage. This splashing results to excessive fluid temps , the transmission end up failing, and the tranny fluid as well degrades very quickly. When an automatic transmission is overfilled, the fluid foams, leading to gear shifting problems, oil starvation as well as transmission damage. On the other hand, an overfilled manual transmission results in fluid-leak from the vent and the shifting the gear becomes a problem when the clutch is depressed.
All transmissions, auto or manual, have some ways to relieve excess pressure. Adding too much transmission fluid can also cause early failure and damage of parts as result of excess pressure.
The pressure in shift from low to maximum in this condition making some parts of your vehicle completely unstable. When you try to change the gears more so on the and as well as the reverse gears this condition can become even worse. You can easily guess how that could do a lot of damages to your transmission.
The pressure would result in friction and easily push out snap rings, break parts, etc. Modern vehicles have transmissions that include a pressure valve which regulates pressure after the pump. However, as previously mentioned excess pressure can result to pre-mature wearing out of some parts — the valve included, thus causing it to fail. Failure of the valve can in turn create pressure related problems in other engine components.
However, there are vehicles that are equipped with transmissions that cannot be overfilled due to their design. They may have a hole on the side to allow any extra fluid to flow out. The pressure plate and the flywheel flexplate are mounted at the back of the engine. The clutch moon is installed on the center axis of the flexplate and is splined on the transmission input shaft.
What is the automatic transmission? The primary difference between automatic and manual transmission is that manual variant requires an extra task for it to function properly. In contrast, in an automatic transmission, the system determines when to up-shift or downshift the gears. The most common automatic transmission uses hydraulic pressure in shifting gears.
It combines a fluid coupling or torque converter and gear sets to up-shift and down-shift into different gear ranges as you step on the accelerator pedal. The fluid coupling connects the transmission to the engine and uses pressurized fluid to shift the gears. The fluid coupling replaces the friction clutch in manual transmission and can halt the car to a complete stop without stalling. The acronym CVT, which stands for continuously variable transmission, is pulley-controlled transmission mostly seen in small passenger cars with small engines.
They are primarily installed in small hybrid vehicles. CVT transmissions have a basic setup of a second large and primary small driven clutch, with a chain or belt that connects both clutches. The chain or belt will sit high in the secondary drive and low in the primary drive when not in motion. As you step on the gas pedal, the secondary drive will expand, causing the chain or belt to walk down, and at the same time, the primary drive will contract, causing the chain or belt to walk up.
Too much transmission fluid causes serious effects that can cost you hundreds of dollars. Erratic shifting: If you pour excess fluid into your transmission, the gear sets and bearings will be submerged in the fluid. And as a result, the gears will find it challenging to shift appropriately.
In other words, too much transmission fluid causes slipping of gear teeth. Foaming Fluid: Overfilled transmission fluid will cause foaming. Over time, it could damage the entire system beyond repair.
Oil starvation: Depending on the transmission size, having a liters transmission overfilled by 1 quart will cause foaming. Extra 1 quart might not have a negative effect on 8lrs transmission.
