In drive (3rd) it does shift a tad bit harder. ever notice if you stick it in 2nd at a stop, and start accelerating, it holds in 1st gear waaay longer than normal (same RPMs and WOT shift point, just part throttle shifts are extended a bit more..). Plus, way more tq in 3rd due to your higher up in the rpms.. so you get movin quite a bit quicker
my primary concern is: why were you messing with another mans shifter
