Car Goes into Gear but Won’t Move: Troubleshooting Automatic Transmission Issues

Symptoms of an Automatic Transmission Not Moving

Engine starts and idles normally.
Transmission shifts into gear, but the car remains stationary.
May hear a grinding, clunking, or whining noise.
May experience a burning smell.

Causes of an Automatic Transmission Not Moving

Low Transmission Fluid

Insufficient transmission fluid can cause the gears to slip and not engage properly.
Damaged Torque Converter

The torque converter connects the engine to the transmission and can fail, causing the car not to move.
Faulty Solenoids

Solenoids control the flow of transmission fluid and if they malfunction, the transmission may not shift properly.
Worn or Broken Bands

Bands are used to engage and hold gears in place, and if they become worn or broken, the car may not move.
Faulty Gear Selector

The gear selector transmits the driver’s gear selection to the transmission, and a faulty selector can prevent the car from moving.
Damaged Transmission Case

The transmission case houses the transmission components and if it becomes damaged, the transmission may not operate properly.

Diagnostics and Troubleshooting

Check Transmission Fluid

Check the transmission fluid level and condition. Low fluid should be topped up, while burnt or contaminated fluid should be replaced.
Inspect Torque Converter

Inspect the torque converter for any visible damage or leaks.
Check Solenoids

Use a diagnostic tool to test the solenoids and replace any that are faulty.
Examine Bands

Remove the transmission pan to inspect the bands for wear or damage.
Test Gear Selector

Operate the gear selector through all positions to ensure it is transmitting the correct signals to the transmission.
Examine Transmission Case

Inspect the transmission case for any cracks or damage that could affect its operation.

Prevention and Maintenance

Regular Transmission Fluid Changes

Change transmission fluid and filter as recommended in the vehicle’s maintenance schedule.
Avoid Overheating

Do not tow heavy loads or engage in excessive stop-and-go driving that can overheat the transmission.
Drive in Correct Gear

Always drive in the correct gear for the driving conditions, such as using a lower gear when climbing hills.
Listen for Unusual Noises

Be attentive to any unusual noises or vibrations that could indicate a transmission problem.

Warning!

Ignoring an automatic transmission problem can lead to more severe damage and costly repairs. If your car goes into gear but won’t move, it is crucial to have it diagnosed and repaired by a qualified mechanic as soon as possible.
