In an automatic transmission, fluid movement is primarily driven by the pump, which circulates Transmission Fluid throughout the system. As the engine runs, the pump pressurizes the fluid, directing it through various components like the torque converter, valves, and hydraulic circuits. This pressurized fluid engages clutches and bands, enabling smooth gear shifts and power transfer from the engine to the wheels. Additionally, the fluid cools and lubricates moving parts, ensuring efficient operation.
There can be several things that will an automatic transmission not to work properly. The most common cause is a lack of transmission fluid. Broken shifting linkage can also cause the problem.
add transmission fluid
I have a 1995 buick centruy and I can move the gear shift lever, but cnnot get the car to move in drive. I have checked the fluid level and it is okay. Is there a cable that is loose or out of adjustment ?
Delayed shifting is because the transmission fluid is not warm enough to move through the internals of the transmission. You may need a transmission service,,,,,fluid change, new filter, etc. Transmission Fluid degrades with age.
My 1991 Buick Century won't move or hold transmission fluid
Automatic transmission- check the fluid level. Level okay? Then you have a serious problem. Manual Transmission- You've burned out the clutch. Replace the clutch disk.
Does the engine rev when you press on the accelerator? If it does check to make sure the emergency brake is not engaged. Is the car an automatic or a standard transmission? You have to make sure it is in gear.If it is a standard the problem is the cluch apparatus, pressure plate etc. If automatic you have to check the level of fluid in the automatic transmission.
Low transmission fluid will cause the vehicle not to move. Try filling the fluid and see if it works. good luck
Transmission fluid is added through the dipstick tube. The dipstick tube is located close to the firewall at the back of the engine on the driver's side. The dipstick handle is yellow and you may have to move some hoses around to see it. To add fluid you will want to use a long funnel, available at the auto parts store or Wal-Mart. Although it is possible to get the fluid in without the funnel, it is much easier with. --Ken
check transmission fluid level bad transmission?
Check the transmission fluid level. This happened to me when the transmission oil was really low. I had to add about 4 quarts before the vehicle would move in either direction. Usually that's a transmission problem (assuming it's an automatic). Check the transmission fluid level. If the fluid is low you might be able to get the vehicle to run by adding fluid. If the fluid is low, check for leaks to keep it from happening again. If the fluid is black or dark red (red with blackened tint) your transmission has been slipping and has failed. If it's a "stick" shift, you'll probably need a new clutch/pressure plate.
Typically when an automatic transmission runs out of fluid, you will notice an increase in RPM's between shifts as well as the shifting nor being as smooth (clunks into gear). When the fluid gets extremely low, the car will simply cease to move as there isn't enough fluid to build pressure to allow the transmission to work properly. At this point, you've likely caused internal damage and fixing a leak/adding more fluid will not help.
