Why do the cams need to be machined before being installed?

Is the lobe lift too high for the 3.0J vs. 3.2J if so, wouldn't a pair of non-S TL cams work as well?

When you get the tranny fluid changed I would recommend a straight drain and refill, not a machine flush. Flushing can disturb it more then help it often. I haven't seen it done on a Honda but I've seen the ill effects on some other automatics.

My sister just had the fluid change done at the dealership at 100k mi on her '02, it didn't quite run the same afterwords, but a return visit and a trip through the diagnostics has cured the issue the car now runs as good as ever.
