AMC Torqueflite 904 turned by a 258 six.

If you leave it in drive, shifts are smooth, crisp and flawless - like a 47,000 mile car should be.

However, if you're feeling rambunctious, and decide to hold it in 2nd, manually upshifting to drive; usually this results in a bit of RPM flareup before finding direct.

Is this something that could be solved with a band adjustment or is this a sign of worse things on the horizon?
