Is There a Problem with Your Transmission?
1. Torque Converter – This hydraulic coupling connects the transmission to the engine. The converter’s components consist of an impeller, stator, and turbine. Torque is the force that allows a vehicle to accelerate after having stopped. If the torque converter begins to fail, the driver may experience slipping and shuddering of the transmission.
2. Clutches/Bands – They help transmissions shift gears through engaging, disengaging, or rotating. Pistons engage pressurized fluid as bands wrap around the transmission to tighten or loosen with respect to the gear the driver uses.
3. Sensors – These are the transmission control units. They calculate engine speed in order to determine which gear is appropriate. Output and input speed sensors are part of the process. For safety, there is also a neutral and park switch.
4. Valve Bodies - They serve as hydraulic control centers that regulate transmission fluid. Valves can determine the gear ratio by the amount of fluid sent to the clutches. Transmission fluid determines which valves will open or close. Engine speed affects fluid pressure.
5. Transmission Fluid- This is a critical component of the system. Another term is ATF. It provides fluid pressure and acts as a lubricant and cooling agent to prevent the transmission from overheating. Manufactures make transmission fluid from a number of synthetic chemicals and oils. Detergents and rust preservatives are added to help keep the transmission clean. Owners should check their transmission fluid once a month. They should service their transmission every 30,000 to 60,000 miles.
How to Tell When There Are Transmission ProblemsTransmissions, like any mechanical device, will wear out and break down eventually. However, proper care and maintenance can certainly extend their life. If your transmission seems sluggish or is slipping, consider the following warning signs:
-Leaking Fluid – Finding fluid on the ground under your transmission is a sure sign there is a fluid leak. A little fluid in the driveway can lead to serious and expensive problems later on. As mentioned, transmission fluid is crucial for shifting gears. If you can sense a sweet or tart smell, it is time to have your transmission checked. Transmission fluid, unlike motor oil, does not burn up or consume with use. If the fluid level is low, there is almost certainly a leak.
-Fluid Leak Causes - They may be due to a recent disconnect of cooler lines, worn gaskets or seals, bell housing damage, a leaking or loose transmission pan, or a drive shaft that is out of balance.
-The Warning Light Comes On – When the warning light comes on, there is a reason. Sensors are responsible for sensing there is something wrong in the transmission system. Transmission fluid is hotter than usual for some reason. Stop the vehicle and check the engine coolant and transmission fluid level. If the problem persists, take the vehicle to the shop immediately.
-Odd Smells – Transmission fluid that smells burned is an indication something is wrong. Transmission fluid normally smells tart or sweet, and it has a red color. Burned transmission fluid means some part of your transmission is burning as well. Call a certified mechanic that can analyze and fix the problem.
-Odd Sounds – Automatic and manual transmissions always give a warning sign when they are about to malfunction. You might hear a grinding noise or a sluggish feeling when trying to shift gears. All of a sudden, shifting does not feel as smooth. As stated before, have a qualified mechanic look at your transmission.
-Movement Delays – Your transmission was designed to lock into gear whenever you shift. If you shift and experience any hesitation, you may have a worn clutch. When your transmission fails to engage, it becomes more than just a mechanical issue. It can be a safety issue as well.Checking the vehicle’s dipstick is one of the easiest ways to determine if there is a transmission problem. It only takes a second, but will reveal if it is hot, discolored, or if the volume is low.
