A few weeks ago I replaced my tranny filter and the fluid that came out during the filter replacement. Ever since that day, I get hard shifts from neutral into 1st gear. The vehicle will rev up and then suddenly clunk into 1st gear. Also, this only happens about 30% of the time.

I've now drained (drain plug only) and refilled the fluid twice now (about 2.5 quarts each time) to make certain I had the correct fluid level. The fluid level was checked by over filling the pan and then waiting for a drip drip from the check bolt after the vehicle had been driven a few miles.

What could this be?
Why would it happen suddenly after the filter and fluid replacement?

Note/Clue: This was the first server this tranny has ever seen.
152,000 miles on my 2002 Ford Explorer 4WD XLT
 












If you used the correct fluid, Are you sure the O-rings were on the filter and did you use a torque wrench on the filter bolt, over tightening could cause a problem.
