A while back I had a small shop close to where I work put a new/rebuilt TH350 and torque converter in 67 el camino along with swapping in a 396 in place of the old 283 and powerglide.
OK heres the problem. It was trailered home after the swap as it still needed glass installed and a few other things prior to its maiden voyage. Besides it wasn't regestered or licensed so i didn't want to run the risk of a ticket. Ok back to the qustion.

While I had it up on stands fixing a brake line leak, thought it might be a good idea to test every thing out before putting back on ground. Checked all the fluids everything was good. Started it let run for a few minutes, sounded good. When i put in gear the wheels hardly turned. So I check the trans fluid level it's dry. It took approx. 6 quarts to bring the level up. Tryed again this it goes but when I apply the brake it stalls the engine. I think the torque converer is locked up and will not disengage when the brake is applied. Does this sound right?
I think the shop did not fill the converter when they installed, and it pumped all the fluid from the trans to it when I started it. Do you think this could have caused major damage? Is there any thing I can do short of pulling the trans and replacing the convertr? Thanks in advance for any help/suggestions, and sorry for being so long winded.
