i have a 2000 svt and i love the way it shifts if im traveling real slow (rush hour traffic) i fell the lurch your talking about but to me its no bad enough to warrent any change.... when moving all gears seem to just fall into place i mean to me there perfectly spaced and the clutch just works
either way if its really a bother to you try some of the fixes here or see if ford could help but to me its really not that big a deal
and about the clutchless shifting its actually quite easy and i do ocasionally in the svt (normally as im coasting to a stop slowly accelerating from my home)
To a stop: just pull it out of gear pull it towards the next gear blip the throttle and it will pop right in gear no grinding or anything
Accelerating: speed up pull it out of gear pull it towards the next gear wait a moment and it should pop right into place as you drive
now of course this is a personal driving method i dont recommend it to anyone i personally just use when im being lazy or if my left foot is comfortable as is.
