Its changed form everyonce in a while to everytime thge car is cold. Progessive at least. I tried sitting idling for about 5 minutes but that didnt do anyhting. Im suspecting the total lack of fluid change for the last 130k has a lot to do with it. Tuesday my transmission lovin dad is gonna heook me up with a free change and a computer diagnostic. Well thanks to Kja nd bill. And John I suppose for making fun of my transmission.
