Simple machines are single, mechanical devices that help improve the daily life of humans by allowing them to work faster, easier, and more efficiently. Simple machines are considered...
You typically hear people talking about gearing or gear ratios when speaking about muscle cars. Gear ratios can be changed in many vehicles, which can result in a change in...
Transmission fluid lubricates all the moving parts of your car transmission, and in an automatic transmission, it also acts as a coolant and viscous fluid that delivers engine power to the transmission. What kind...
Aspiring mechanics spend hours learning about how main gears and planetary gears work in a car transmission, so a full dissertation simply isn’t possible within this relatively brief article. If you’re curious...
The gear shifter allows the vehicle to be put into different gears on a manual transmission. In an automatic transmission, the gear shifter is known as a gear selector. The gear shifter is...
Hello, thank you for writing in. While these issues are frustrating, it is best to take this kind of diagnosis step by step. The most common cause of these symptoms is low transmission fluid. The automatic transmission relies on the...
Hello, thank you for writing in. The automatic transmission starts in first gear always. Considering the age of the vehicle, there are a large number of components that can be contributing to your symptoms. Start with the simplest fixes. When...
Hello, thank you for writing in. The first step is to see if you can manually switch the transmission into a gear where the gear selector connects to the outside of the transmission. If you cannot, there is an interior...
Hello, thank you for writing in. The vehicle is likely experiencing issues with the transmission. The first step to take is having the vehicle scanned for diagnostic codes, and use them to help point you in the right direction. If...
Hello, thank you for writing in. Typically no response from the transmission is a sign of a failed hydraulics. This is most commonly caused by low transmission fluid, a clog or hydraulic valve issue, or transmission failure. You will want...
Hello, thank you for writing in. Start by tightening up the linkage. You can even make adjustments to the linkage to compensate for wear. The transmission pan should be taken off and inspected. If there are any signs of mechanical...
Hello, thank you for writing in. The symptoms you are having are due to transmission issues. To start, you need to check your transmission fluid level. Low levels of this hydraulic fluid will cause issues with the transmission shifting into...
Hello, thank you for writing in. When having issues shifting, the first thing you want to do is check the level of your transmission fluid. The hydraulic fluid is what allows the gears to be changed, and it is a...
Hello, thank you for writing in. The transmission utilizes a planetary gear set to obtain different gears when you select them on your shifter. The planetary gear set may have become stripped or broken and it will need to be...
This may suggest the transmission synchros may be wearing out. Your transmission has small gear synchronizer rings that help to move the transmission in and out of the various gears. When these begin to wear out, you may notice it...
Hello, thank you for writing in. Assuming the vehicle is an automatic because you had it in park, you should be concerned about the transmission. This is a classic sign of failure, and you will want to have it looked...
Hello, thank you for writing in. Without the vacuum supply from the engine, the brakes become hard to press. The vehicle is designed not to start when it is in gear. This is a safety measure ensuring the vehicle is...
Hello, thank you for writing in. The first assumption we make when the vehicle does not move while in gear, is that the transmission fluid is low. Start by checking the level and the condition of the fluid. If it...
Hello, thank you for writing in. Your vehicle is typically rear wheel drive, when you have it in 4-Hi then you are telling the front wheels to engage with the transmission. The fluid is then pressurized and the gears mesh...
Hello, thank you for writing in. The first place to start is to check the level of the transmission fluid. If the level is low, then the hydraulically controlled transmission will not reach the pressure it needs to perform. With...
Your 4WD will work until the pinion gear cracks or breaks due to the odd wear of the ring gear that has 4 broken teeth. First, recommend that you drain the fluid and fish out any broken metal and debris...
Either the transmission has thrust bearings or bushings that are worn causing the internal parts to go out of balance or there is an issue with the fluid is low causing the gears to slip. If the fluid is full...
Hello, thank you for writing in. Unfortunately, there are a large number of components that can contribute to this issue. The first thing you will want to do, regardless of a check engine light being present or not, is to...
Hi there. Sometimes this type of problem is caused by internal transmission issues. It can be as minor as the transmission fluid being 'dirty' or the hydraulic lines being clogged with debris; requiring transmission fluid to be flushed and the...
Hi there. It sounds like the reverse input gear has ground off and now the high gear which is for direct drive of overdrive is engaged. I recommend seeking out a professional, such as one from Your Mechanic, to help...
