Leaks commonly come from a worn pan gasket, a failing seal, a loose fitting, or a damaged cooler line. Where the leak is — and how much must be removed to reach it — is what drives the repair cost.
A leak lowers the fluid level, and low fluid is a leading cause of slipping and overheating. Addressing a small leak early is far cheaper than repairing the damage that low fluid can cause.
As an educational range, from modest for a simple gasket to over a thousand dollars for a leak needing more disassembly. The source of the leak determines the price.
It can become serious if ignored, because low fluid causes slipping and overheating. Catching a leak early keeps the repair small.
Monitor the fluid level closely and have it repaired soon. Running the transmission low on fluid risks far costlier damage.
