Oops - I didn't mean to type "engine" - I meant the transmission. But your additional comments make sense.

The 4.6is (and 4.8is) supposedly have more heavy-duty transmissions than 3.0 and 4.4 X5's, but I think all of your comments still apply. I'm just finding that since I got the Dinan S3 upgrade, I have an urge to keep RPMs higher (on average) than I did before (perhaps to hear the throatier growl of the Dinan exhaust) , but I suppose as long as I don't get carried away, I shouldn't cause TOO much damage...
