Did you notice whether or not the trip or main odometer were near a multiple of ten? Typically when the odometer's break, they will break right before one of them (usually the trip) hits 9.9, 19.9, 199.9 etc as this requires muck more power to turn rather than simply the 1/10mi dials.

Also remember that you should always reset the trip odometer when stopped!

I had a problem with my trip odometer, as it's primary gear broke free from it's powering shaft. I imagine that if the gear didn't break free it could have broken the cable. Used superglue and adjsuted spring tension to fix. That has worked for the last three years.

Otherwise, I agree that It's most likely some type of kink. Also, I'd use standard gear oil to lubricate the cable, not ATF, as ATF has other conditioners.

if you remove the speedometer, you can turn the female cable acceptor with a drill equipped with a square drive bit. Use this to see if it all looks like it's working right.
