I got a used trans off a guy that had 50 miles on a ats build, he blew the main seals in the engine and that's why he was parting out the truck. So I got the transmission installed and it ran great for a half hour during the trans relearn. i get back to my driveway and when I stopped to put my truck in reverse I heard a very faint odd clunk when shifting from drive to neutral, and then had no reverse. Put it in forward and the same thing, nothing. So I put it back in reverse and give it some throttle and the truck started to move slowly so I revved it up enough to back it into my driveway. I got off the phone with mike L and he was helpful in telling me to pull the internal filter and if it was clogged up then the trans is toast. It has a few pieces of debri inside the filter but doesn't seem in any way to be clogging it up. Now I'm wondering what you all think? How could it wipe out forward and reverse at the same time? Could it be the pump being bad and not giving any pressure to the tc unless there is a lot of rpm? I just had head gaskets done on the truck and I'm drained of money. Any help is appreciated. Thanks
