4R44E "slipping" from 4-OD
Ive got a 2000 with a 3.0. I've only had the truck a month, but the tranny has recently started acting up. It shifts fine hot or cold through all gears except overdrive. It will slip or flare until I back off the gas. It usually will drop into OD then, but sometimes it still acts up. Once it's in OD it dosn't have any issues. However, if I let off the gas and then ease back into the gas, it feels like it's slipping or possibly stuck in 4th until I Rev it a little and then ease off again to get it back into OD.
I know the transmission needs to be flushed, but would this cause a problem only with overdrive? Any help would be greatly appreciated. :-)
