flashing d4 light on 1995 Acura Legend

D4 light keeps blinking when I drive my 1995 Acura Legend. When I drive on D4, I can see the rpm go up but the car makes different sound and it does not accelerate. I can drive on D2 or Di without any problems. I looked up into forums and found similar problems associated with VSS. What do you think the problem might be? Thanks in advance.

The Blinking D4 light means that the Transmission computer needs to be Diagnosed, because there is a malfunction. http://repairpal.com/automatic-transmission-diagnosis
