I drive mine like a manual shifter around town...including a throttle blip in the false neutrals between gears when downshifting...
It's even worse since GT-5 launched...
If you're REALLY worried, take it all apart & goober up all the possible wear areas with Mobil 1 grease.
There's been a couple around here that have tried, but for some odd reason, positive results were never posted. (use search for moron that)
I think they were MLM's...
