Need Some Advice. There was only 115K miles on the truck. My original transmission went totally bad couple years ago, Vehicle sat for two years do to health reasons. Replace it with a used transmission with 90K on it last May and in July, I started having this issue with my replacement 5R44E transmission, it does not do it all the time. When you put it in drive does not do anything, but you can put in second gear an take off then shift to drive it does fine. It up shifts and down shifts fine. But when you park and turn the engine off, sometimes you have to do it all over again. Other days it will drive fine for a few days then acts up. I have been told it could be the valve body or solenoids, I ohm'ed the solenoids checked out good. Thought about putting new valve body gaskets on it. I was sent another transmission from the warranty place where I bought it from. Wanted to wait before changing the transmission. Could use some advice. Thanks
