I changed the fluid in my N/A auto tranny by unbolting the pan, replacing the transmission filter and gasket then adding fluid in through the fluid check funnel under the hood. All the while using a pump to guess where the good level was after finding out that the check rod is wrong. I have no idea how the the tranny fluid level checker is the wrong one. All I know is that after replacing it to the ideal level on the checker I went to test it out and sat in my car as it rolled down the driveway without the gears catching in the tranny, I took some out and now it works fine.....for the most part. Can anyone tell me a sure way of making sure it's at the best level possible?

 

your manual has specific instuctions on how to change the check the fluid

i dont know about for rx7s. but for my moms car it has to be running and in neutral
