I have an issue with my transmission. It drives and shifts fine. I just replaced the filter and drain both the converter/pan. I put Valvoline Dextron III in it as that's what I've seen these cars need.
My issue is that often, when I pull up to a stop light, the transmission goes into a free spinning mode for a few seconds, (like I put it into neutral or the fluid was low), and then catches again and is ready to go. I don't know much about transmissions and was hoping the filter/fluid change would fix that, but it didn't change a thing.
Any suggestions? I am thinking the hydraulic pressure is not keeping up or low at idle or something. Wondering if I should drain out some fluid and add an additive such as Lucas Stop Slip or some other snake oil type stuff that seems to work. Wondering if seals are not keeping the pressure....
