727 woes.

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?

A rebuilt 727 is not a guarantee either.

It sounds like both of these may have been beat on pretty good and should probably be gone through. If you have two cases why not start with one that's not cracked. Ask around, maybe you have a local facebook mopar group page or mopar club or whatever - I was able to find someone to rebuild mine for 1k, I supplied a new converter and shift kit. As it turned out the guy owns a major brand name shop and has a 70 Challenger himself, has done literally thousands of 727s. Couldn't ask for any better than that. Calling around random other shops were quoting me 2k-2500. When you put it back in be sure to add a quart of fluid to the converter before bolting the trans up to the engine.
