After changing the ATF fluid today, I set the car back down on the ground and went to start it, but got a brief error message on the MFD that I didn't have time to read, though it said something about an abnormal trans lock. The message disappeared, and then the shift pattern display on the dashboard started flashing. I couldn't go into forward or reverse, and the red brake light on the dash board stayed on even though the parking brake had been released. Everything had been fine before changing the ATF fluid, and I've never seen this problem before, so I'm guessing that when the trans fluid is drained it triggers a "low fluid" sensor that prevents the car from starting so as to protect the transmission from being damaged. Adding the new fluid obviously doesn't appear to have cleared the sensor generated data, so my question is how does one do that? I read something that someone posted at another site regarding trans fluid changes, and he said that after changing the fluid you should go into the MFD and "reset the trans fluid counter." Does anyone know how to do that? How is that function accessed? Thanks in advance for any help you can offer that will clear this problem.
