Will a overfilled transmission cause it to not shift?

As stated above, automatic transmission relay on pressurized fluid from the torque converter to function. If you overfill it, the transmission will experience hard shifting and slippage. Another consequence of overfilling your transmission is that it will cause the fluid to lose its lubricating properties.

How much water does it take to mess up a transmission?

This can quickly lead to rust buildup, expanding, adhesive loss on the clutch, and dangerous vapors. The longer it’s driven with the contaminated fluid, the more damage it does. And it doesn’t take much. Just a tablespoon of water can cause complete failure to your transmission parts.

Can you siphon transmission fluid out?

Most automatic transmissions require that you drain and fill the transmission fluid via the dipstick tube. Fortunately, you can purchase an oil siphon kit that comes with a small hose and small pump that will suck the oil out of the dipstick tube.

How do you know if there’s water in your transmission fluid?

If your transmission fluid looks like a strawberry milkshake, you’ve got water in the transmission. Once water gets into the transmission enough to affect operation, a rebuild is required. It doesn’t take much–less than an ounce of water can cause problems.

Can you suck transmission fluid out of the dipstick?

Why does my transmission fluid look watery?

When water gets inside of an automatic transmission, the friction lining of the clutches absorbs it and dissolves the glue that attaches the material to the clutch plates. Usually, some amount of water will come out of suspension and form white gummy masses in various areas of the unit.

Why does my transmission fluid look milky?

The milky substance you are seeing on the transmission dipstick is a result of cross-contaminated coolant and transmission fluid. These clutches are made of a hygroscopic material, which means that when they are exposed to any moisture they will displace ATF (automatic transmission fluid) for water.
