Checks before purchasing a car with an automatic transmission:
Visual inspection:
* Check for transmission fluid leaks under the vehicle.
* Inspect the transmission pan for damage or rust.
* Check the condition of the transmission dipstick and make sure that the fluid level is correct.
Test drive:
* Acceleration check: Check for smooth gear shifting during acceleration. Make sure that gears shift without slipping or jerking.
* Braking check: Check whether the gears drag when braking. The transmission should downshift smoothly.
* Idle Speed Check: Check if the transmission goes into neutral when the vehicle is in park. Make sure the vehicle does not roll backwards on an incline.
* Kickdown check: Press the gas pedal to the floor to check if the transmission downshifts from low engine speeds.
Diagnostic testing:
* Run diagnostics on your vehicle’s on-board computer system to check for transmission fault codes.
* Consider having it inspected by a qualified mechanic who specializes in automatic transmissions. They may carry out more detailed checks such as:
* Checking the condition of the transmission fluid
* Checking clutch wear
* Checking the condition of the torque converter
Service history:
*Ask the seller about the vehicle’s service history to ensure that transmission fluid and filter changes have been performed on time.
* Check to see if there have been any transmission problems or repairs in the past.
Additional tips:
*When purchasing a used car with an automatic transmission, choose a model with known reliability.
*Consider purchasing a powertrain warranty if available.
*If you hear any unusual noises or experience problems shifting gears, do not buy the vehicle.
