If you add too much transmission fluid, you will notice that it may foam, and that can bring about erratic gear shifting. Some other problems that may arise include oil starvation and transmission damage. … Adding too much transmission fluid can also cause early failure and damage of parts as result of excess pressure.
What are the signs of an overfilled transmission?
Overfilled Transmission Symptoms
- Higher Fluid Level on Dipstick. If you think you might have put too much fluid in the transmission, the problem is easy to spot by looking at the dipstick. …

How long does it take for transmission fluid to cycle through?
AUTOMATIC TRANSMISSION: How long does it take for transmission fluid to be pulled from the pan and circulate through the transmission after you start you car and shift into drive? Probably about 5 seconds. Roughly 5-10 seconds to fill all the tubes, channels, cracks, and crevasses.
