You could check line pressure. Does it have reverse? If it's got normal line pressure it's probably a mechanical problem, maybe a forward sprag.

 

Checking line pressure can be difficult if you are not tooled up for it.

My recommendation would be to spend a few dollars to have it inspected by a reputable shop near you. It might save you the time and trouble of pulling it and shipping it.

Good Luck

sounds like the same thing that happened to me. My issue was the front pump grenading itself. My transmission was also built for performance and was from a reputable shop.

 

A quick check for pump failure would be to remove a line from the cooler and start car if fluid flows pumps working if not then theres your problem.

 

thanks for all help ill have my brother do the things that you guy have said and ill let you know
