So, dropped my trans pan earlier to change the filter and put new fluid in. Dropped the pan, cleaned it, cleaned the bolts, put them back on, filled with a little less than 5 quarters of transmission fluid. Now, it seems like there's a grinding when shifting from 1st to 2nd and 2nd to 3rd. It's noticeable at first then goes away as I raise RPMs. This car is killing me. Any clue what it might be?
