There are a number of things that can cause a transmission leak, including:

• Damaged or worn gaskets or seals
• Cracked or damaged transmission case
• Loose or missing bolts or nuts
• Overfilled transmission
• Internal transmission damage

The most common symptom of a transmission leak is a puddle of fluid under the car. However, there are other symptoms that you may notice, including:

• Slipping gears
• Difficulty shifting gears
• Noisy transmission
• Burning smell
• Check engine light

Repair Costs for Transmission Leaks

The cost to repair a transmission leak will vary depending on the cause of the leak and the extent of the damage. However, you can expect to pay anywhere from $200 to $2,000 for repairs.

How to Prevent Transmission Leaks

There are a few things you can do to help prevent transmission leaks, including:

• Check the transmission fluid level regularly.

If you suspect that your car has a transmission leak, it is important to have it diagnosed and repaired as soon as possible. Ignoring a transmission leak can lead to costly repairs or even a complete transmission failure.

Transmission Leak Diagnosis

To diagnose a transmission leak, a mechanic will typically:

In other cases, more extensive repairs, such as replacing the transmission case or rebuilding the transmission, may be necessary.
