Good morning.

I drive my car through some heavy flowing water one day and after that the vehicle has develop multiple issues..

When the vehicle comes to a halt the transmission slams. On the dash it shows that gear box is at fault and when I pull the oil bung or plug on the transmission, the oil that runs out the transmission has a different color in appearance.

Do you know if water can get inside the transmission if I drive through heavy flowing water to cause this problem?

Additionally, the vehicle is driving in limp mode and whenever time I try to move it, it is not accelerating. Also, the rev count and speeder meter are not moving. The battery light also comes on. The vehicle is also throttling high and not taking any rev.

Thank you in advance for a speedy response.

Hello,

You can get water in the transmission but it is not as likely. However there is a good change you got the electrical systems for the transmission wet.
Is your check engine light illuminated? Sometimes transmission fault can trigger the light as well.

Since you do not have speedometer or tachometer functional it is likely you have water in those sensors and wires. Which can short out the system or have corrosion.

Have you given it few days to dry out? Unless the circuits got shorted out due to water, they might work after drying.

Let me know if you are able to get it scanned and let me know any codes.
Thank you.
