Eastern Pa Transmission Shop

Anyone know of a good shop, I am looking to have my 904 transmission rebuilt here in the Allentown/Bethlehem area. I was thinking about going with Cope and getting a replacement but it appears they are out of stock. I am pretty sure the trans is original and its making weird noises like a whining sound. I've changed the fluid and filter. The car was born with a 318 but was replaced with a 360 along the way.
