Vickie,
When you had the transmission pan off the vehicle, was there a lot of dirt built up in it? If it was working correctly and now is doing this again, it does sound like something could be plugged. If you check the fluid, is it still clean since the change?
As far as the ABS, that wouldn't be causing this type of issue. You could even have a plugged transmission cooler.
It may be a good idea to perform what is called a line pressure test to confirm if the transmission fluid pressure is within spec. Before that, however, let me know what the new fluid looks like. Also, see if it has a burnt smell to it.
I will watch for your reply.
Take care,
Joe
