Sioux Falls SD Transmission Leaks Service

With extensive expertise, Team Automotive in Sioux Falls excels at diagnosing and repairing transmission leaks. When customers report a puddle of red fluid under their car, we inform them it usually signifies a transmission fluid leak, which can be costly and cause unsightly stains.

To assist our customers in understanding transmission leaks and the associated repair costs, we have provided the following information.

Major Causes of Transmission Leaks

Transmission leaks can stem from minor to severe issues. Regardless of the severity, Team Automotive advises Sioux Falls customers to address leaking transmissions without delay.

Even minor repairs, if postponed, can worsen and become more expensive. Below are the five most common causes of transmission leaks handled at Team Automotive.

#1 — Drain Plug or Pan

The transmission pan undergoes wear and tear over time, similar to other vehicle parts. Damage often comes from driving conditions where road debris and rocks hit the pan.

A punctured pan or loose bolts and drain plugs can cause leaks. Major impacts can result in rapid fluid loss and immediate performance issues.

In contrast, small punctures cause slower leaks that might go unnoticed. Improperly secured or over-tightened drain plugs and bolts, especially after fluid changes, can also lead to leaks.

#2 — Broken Transmission Seals

Automatic transmissions rely on seals to maintain hydraulic pressure. Over time, these seals can crack and wear out due to heat exposure.

Cracked seals can cause leaks in various parts of the transmission. Common leak points include the input or output shaft, but leaks can also occur in the pan, driveshaft, plugs, sensors, shifter housing, valve body, tail housing, or speedometer input.

#3 — Transmission Pan Gasket

Poor manufacturing, improper gasket alignment, and prolonged heat exposure can damage or crack a transmission pan. Replacing a gasket is relatively inexpensive but should be done promptly to prevent severe damage and costly repairs.

#4 — Leaking Torque Converter

The torque converter's primary function is to distribute fluid into the transmission. Cracks in the converter or damaged needle bearings can result in fluid leaks.

#5 — Cracked Fluid Line

Transmission fluid lines, usually made of aluminum or steel, can also cause leaks. Despite their durability, these lines can crack or break due to heat and debris impact.

Typical Transmission Leak Repair Costs

Repair costs for a transmission leak vary widely. If the transmission doesn't need removal, repairs can be as low as $75. The least expensive fixes typically involve replacing pan bolts, drain plugs, gaskets, seals, and fluid lines. Costs depend on the complexity of the leak, damaged parts, and vehicle type.

Team Automotive informs customers that the final repair cost depends on the leak's location. For instance, a front seal leak requires transmission removal, increasing the service cost.

Inspection Process

When a vehicle with a leaking transmission arrives, Team Automotive specialists first determine the leak's origin by observing the fluid's drip point.

Leaks often travel along the path of least resistance. If a loose part causes the leak, our specialist will properly tighten it.

For leaks due to cracked or worn parts, replacement is necessary. Team Automotive provides a repair estimate before any work begins.
