Quick Answer: How can I make my automatic transmission shift smoother?

What would cause an automatic transmission to shift hard?

Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.

Why is my transmission not shifting smoothly?

One main reason why the automatic transmission in your car may not be shifting smoothly is the ECM is going bad. It is best to get this checked out by an experienced auto mechanic technician who understands the electrical system. Other indicators include bad connections within, or worn out sensors and faulty solenoids.

What does it mean when your transmission downshifts hard?

One of the first symptoms of a bad or failing downshift solenoid is erratic shifting. If the downshift solenoid has any issues, it may cause the vehicle to behave erratically when downshifting. A bad or failing solenoid may cause the vehicle to experience hard or erratic shifting when slowing down or coming to a stop.

Can too much transmission fluid cause hard shifting?

If you overfill it, the transmission will experience hard shifting and slippage. Another consequence of overfilling your transmission is that it will cause the fluid to lose its lubricating properties. It could also lead to the entire system blowing up and not functioning.
