I have a 91 acura legend and my car just started acting crazy. When I crank the car and put it in D4 it seems like its stuck in neutral no matter how hard you push the gas then after a couple seconds it goes in drive. The car only does it after you cut it off. If you stop at a light it shifts fine. I have no D4 light blinking or anything.I changed my transmission fluid and differential fluid within the past month. The transmission was recondition about 90k ago. I don't drive the car hard it my daily driver to work. Any suggestion what this might be hope the tranny is going out
