Do I need a new transmission?

I own a Sport Trac (2wd) an has the 5r55s transmission. I replaced the solenoid pack and connector because they failed. After I replaced them, my truck wouldnt move forward even when the shifter lever was in Drive position. After I added some fluid, it finally did move forward. I drove it a little while then parked and turned it off. When I started the engine back on, the truck would only move backwards, even with the shifter level in N, D, 3, 2, 1. Do i need to rebuild the transmission or what can cause this problem?

Note; the shifter level moves in any position without any issue, the computer seems to know what possition it is since i can see it in the dashboard,, it even turns the back up lights when in reverse.

Sounds like it's a mechanical internal tranny problem and a rebuilt transmission would be best. Who diagnosed the shift solenoids incorrectly? They are easy to monitor with a scan tool.
