4L80E Shifting Problem

I have a 93 3/4 ton with a 6.5. Tranny started occassionally slamming into 2nd and all the rest of the shifts were good. now it slamms into 2nd all the time even at low RPM and now have lost "OD" . I havn't owned it long and it needs a fluid change. But I don't want to change fluid if I need some internal parts such as a solenoid. The dipstick tube overflowed once and the fluid coming out seemed to be aerated, after the fluid settled the fluid level was low. I had to put almost a gallon in to make it read correctly.Any help would be greatly appreciated.
