Trouble with our 727.

[SteveSS]

We are 99.5% done with the 71 Charger 500. 383 AT. We had two 727s to choose from. The one that was in it and a spare. The first one we filled up through the tube. Putting it in gear it felt like the brakes were locked up. They weren't. It would move but barely at higher rpms. We took it out and it felt like the torque converter wasn't full. We put the other one in, filled it up and it has a crack by the shifting mech. I researched brazing aluminum and it looks pretty easy with Hobart rods. Anybody have any good ideas?

Rebuilt ones are close to three grand. Yikes!

Rebuild the trans with the undamaged case.

This sounds like a TIG job. Look around for a local shop that can aluminum weld for a permanent repair. That crack should not take more than 30 minutes for them to fix, including time to properly clean the area.

My trans had a chunk taken out (about and 1" square) that was put back in place and TIG welded up. Good as new!
