Identifying Transmission Damage Caused by Water and Prevention Strategies

Introduction

Water in a transmission can lead to severe damage. This article delves into the signs you should watch out for and the preventive measures you can take to protect your vehicle. If you suspect water in your transmission, we'll guide you through the steps to diagnose and manage the issue effectively.

Symptoms of Water in the Transmission

Dipstick Check

For vehicles with manual transmissions equipped with a dipstick, an overfilled transmission fluid, particularly if it has a strawberry milkshake appearance, is a clear indication of water. Overfilling and a milky appearance are strong signs that water has been mixed with the transmission fluid. Since water is denser than oil, it settles at the bottom of the transmission. Drain and refill the transmission with the proper fluid to mitigate the issue—and you might need to repeat this process several times for automatic transmissions to eliminate all the water.

Visual Inspection

For vehicles with no dipstick, conduct a visual fluid-level check. If the fluid level appears overfilled and the fluid looks milky, water is likely present. The presence of water can lead to rust and lack of proper lubrication. Carefully observe the transmission fluid for any signs of foaming, which can indicate contamination. A brown-ish substance or crud also might suggest the presence of water. Using a drain plug can offer a more straightforward method to check for water. Place your car in different gears, and if the scenery outside changes even minimally, it may indicate that the transmission is not functioning properly due to water contamination.

Preventive Measures

To avoid water contamination in your transmission, it's essential to perform regular maintenance. Keep a close eye on the fluid level and color, and address any unusual signs promptly. Follow a schedule for regular oil changes and check the transmission for leaks. If your transmission is prone to miscellaneous leaks, consider getting it sealed or replaced. Proper maintenance can help prolong the life of your transmission and keep it running smoothly.
