Default auto shifting problem???help

Here goes: When I start moving, and get up to 10mph(when the car is supposed to shift to 2nd) the car will not shift, it will just let the revs build, then eventually shift. Either that or I will let off the gas and it will shift.

Also when I am going over 100 and it shifts into 4th, it will kind of slip back into 3rd sometimes.

Please help, what could this be: Torque converter, rear end gears, driveshaft, or *gasp* tranny itself?

any work done recently to the trans?
mine did that right after it's rebuild, turned out to be a stuck valve, 2nd time was a charm

no work done on the tranny ever, AFAIK.

Would changing the tranny fluid help, and if so where do I drain it from?
