Auto trans 46re issue

thanks for all the great advice. Hopefully i will have the barracuda back on the road in the next week or 2 so i can pull the truck in and start on it. Most likely will be pulling the motor anyways, its needed a rebuild for the past few years. but now that you mentioned i the check valve issue i remember hearing about years ago. I have alot to check now, thanks for the pointing in the right direction!!!
