When I put the shifter into "1" it has plenty of power, when put in "2" it acts normal; however, when I put it into "D3" the car slowly accelerates and acts like it has no power. When I shift it to "D4" it acts like its in Neutral, and the light on the dash doesn't even show it in "D4" like the others.
Anyone have any ideas?

 

Check your trans fluid? Sounds like the trans might be on its way out.

 

Does the D4 light ever come on? When starting the car, there is a bulb check. Turn the key to on/pos II-does the D4 light come on?

Nus-I'm wondering if the D4 bulb is burnt out, blacked out or removed.....there could be codes.
