What problems can occur with the transmission of a flood-damaged car?
2 Answers
Water entering the transmission of a flood-damaged car can lead to the transmission being scrapped, with minor cases causing burnt clutch plates and requiring major repairs. Here are specific details about flood-damaged cars: Interior Impact: Prolonged soaking can cause materials like carpets and seats to deform, become rough, and produce odors, leading to bacterial growth. Moisture in the wiring harness beneath the carpets can cause short circuits due to dampness. It is best to replace all soaked components to avoid long-term issues. Door Trim Impact: The door panels contain soundproofing material that needs replacement after water exposure. The four-wheel bearings must also be replaced because their seals contain lubricating grease, which can corrode and deteriorate, failing to provide lubrication and compromising driving safety.
I've repaired many water-damaged transmissions. Generally, after water ingress, the fluid mixes with water and deteriorates, completely losing its lubricating properties. The gears and bearings become severely rusted, making the car drive like a rusty machine struggling to function. The electronic control unit of automatic transmissions is also prone to short circuits and malfunctions, leading to jerky gear shifts or complete failure. If left untreated for a long time, rust debris can clog oil passages, friction plates may detach, and wear intensifies, eventually requiring a full transmission replacement at a high cost. After driving through water, don't rush to start the car—tow it to a professional shop immediately to check the fluid color and replace the oil and filter. If flushing isn't effective, a deep cleaning or component replacement may be necessary. Remember, water-damaged transmissions aren't just a mechanical issue—they're a safety hazard. Sudden transmission lock-ups can cause accidents at high speeds, so timely maintenance and preventing water ingress are essential.
