Can a CVT Transmission Drive Through Water?
2 Answers
CVT transmissions cannot drive through water. Below are relevant details about CVT transmissions: 1. Consequences of water exposure: After driving through water, if the transmission fluid is not replaced promptly, residual moisture in the fluid can reduce lubrication effectiveness, leading to accelerated wear of components such as chains and cylinders. Additionally, changing the transmission fluid is crucial. If the fluid in the hydraulic pump is too dirty, it can also cause transmission wear. 2. Advantages: The benefits of CVT transmissions include smooth power delivery, true continuously variable transmission (CVT) operation, simple structure, and lower cost compared to AT transmissions. However, CVT transmissions lack the excitement and sporty feel during driving.
I usually enjoy studying car structures, and CVT transmissions are indeed not suitable for deep water wading because their core components, including the drive belt and pulleys, are enclosed within a sealed housing. If water gets inside, it can flood the interior and corrode the electronic control unit. Manufacturers generally recommend that the water level should not exceed half the height of the wheels, meaning it shouldn’t reach the center of the wheel hub. When wading through water, maintain a slow and steady speed—don’t accelerate abruptly, as the water pressure impact can easily damage the seals. Afterwards, remember to check the color of the transmission fluid; if it turns milky white or contains debris, it indicates water ingress and requires immediate repair. Controlling the wading depth is crucial—I’ve seen many car owners neglect this and end up with a ruined transmission.
