usually it is the overdrive solenoid, but can be the connector to it, input to the computer, or the computer.
The most common cause of a automatic transmission jerking, when shifting, is low transmission fluid. Fill the transmission to the full mark.
a bad radiator -automatic portion of radiator not cooling off transmission
your transmission is about done, sell it
A gear which causes the transmission output shaft to rotate at a higher speed than the transmission input shaft.
Assuming it is an automatic transmission, I would check the fluid level. When the transmission is warmed up, the level should read 'full' on the transmission dipstick. Check the color and smell of the oil. Does it smell burnt, or does it appear to be brown instead of red? Perhaps the filter screen is clogged.
Possibly low fluid.
There is a push button on the end of your automatic shift lever. Pushing it in causes the Overdrive to turn on and off.
Your transmission is breaking down inside. ether watch for it. or extensive transmission is required.
There are several causes that an automatic transmission will not want to shift into second gear. The two most common causes are transmission pump issues and trouble with the vacuum modulator.
The transmission needs repair. The electronic control system causes the transmission to stay in 2nd gear when it detects a problem, such as slipping in 3rd gear or overdrive. This allows the car to be driven in an emergency.
low gear oil or gears are worn.
could it be low fluid
A seized up transmission can cause a Volkswagen Golf with an automatic transmission to not shift and racing RMPs after second. A worn gear can also prevent shifting.
no tranmission fluid in it or it maybe your tranmission is bad because you keep grinding your gears up but for a automatic its your transmission fluid
The bands may be weak, it may be low on fluid.
If the car is automatic you must have the footbrake applied to shift from park.
A howl in an automatic transmission between speeds of 60 kph and 80 kph could signal a problem with the fan belt. Another cause could be an issue with the torque converter.
governor on side of transmission inoperable,not spinning its a centrifugal switch.
Low fluid, shifter malfunction, electrical malfunction, internal mechanical malfunction.
Indicates a problem with the automatic transmission. Seek professional help.
You need to check the transmission computer for codes to know possible causes.
most likely your transmission is slipping and usually is the onset of your transmission going
An automatic transmission might be slow shifting from first to second because of low transmission fluid. You might also have damaged the gears in the transmission at the area between first and second.
