In route to Mopar Nationals, my Roadrunner broke down. We were cruising down the interstate at 60 mph or so and the transmission just downshifted to second. No sign of any slippage. Throttle linkage was set right and it seemed to have plenty of throttle pressure. No leaking and fluid looks and smells clean. Still shifts through first and second, but no reverse either. Guessing I lost a band or clutch pack. I'll be pulling the transmission this week and probably bringing it to a friend for repair, but I'm looking for some advanced pre-diagnosis.

I can fix it... my old man is a television repairman. He's got the ultimate set of tools... I can fix it.

So... what causes it to blow out? Mis-assembly?
Do I need to remove the transmission and tear it down to replace the seal, or can it be done in car? Got a part number for the seal?
Point me to the right page in the FSM. I'm flipping through looking for it.

Only owned the car about a month. PO claims it has a few thousand miles on it.

No. It was a cast iron seal. I may have the description wrong.
