95 honda accord shifts from 1st to neutral and stays there. VSS or worse?

I have a 95 accord that stopped shifting correctly on the way home. I can get it into reverse, but it is very hesitant to go into first. When it goes to shift to second while accelerating, it drops to neutral and stays there until the car comes to a stop. Once the car warms up it seems worse and doesn't want to go into 1st at all. Tranny fluid is full and relatively clean. "D4" light is not flashing. Check engine turned in a few times in the last week but turned back off preventing me from scanning. Someone suggested it may be the speed sensor but I'm skeptical. Any experts or folks with experience possibly able to shed some light on this?

Speed sensor has nothing to do with it. Find local shop at ATRA.COM sounds like its time for rebuilt transmission
