Hi, Guys,

I have a '56 T-Bird (312 c.i., auto trans) that has a Cruise-o-matic from a '58 in it.  I didn't put it there, it was that way when I bought it.  The transmission tends to kick down on the highway once it heats up (45-60 minutes of driving will do it), which is alarming, at minimum.  I've had the bands adjusted, with no perceptible improvement.  

Thinking about ditching the Cruise-o-matic in favor of an AOD.  I think there was some discussion about that on this forum years ago.  Is there any newer wisdom on the topic, like whether this is a good swap, who has the best parts, etc?  Any advice would be welcome.

Thanks,

Tom
