Pro shifted transmissions are not meant for street use. They are designed for the racetrack and full throttle shifts. There are no synchronizer rings in a pro shifted transmission, so they do not engage smoothly at speeds less than full throttle.
The following was copied from Liberty Gear's website. Liberty is a well respected racing transmission manufacturer. See http://www.libertysgears.com/faceplate.htm
"Pro shifting and face plating serve the same basic purpose, a bigger window for engagement to prevent missed shifts. Neither are synchronized, so they make street driving difficult. Contrary to popular belief, YOU MUST USE THE CLUTCH when shifting with either system. Although it is mechanically possible to shift without the clutch, the shock load of a clutchless shift can cause severe damage to the transmission. We do manufacture a clutchless transmission with a starting price of $7580.00.
Face plating is preferred over pro shifting, but it slightly more costly (initially) than pro shifting. In the long run you will find that face plating is more cost effective due to less wear on engagement components.
With pro shifting, as the pro rings wear from normal use, they burr up and require dressing, deburring and/or replacement to maintain smooth shifting.
With face plating, the engagement lugs are on the face of the slider and the lugs also have a much larger contact area, so in the unlikely event that they burr up, it will not affect shift action. Due to the design of the shift lugs they are more durable, so longevity is increased dramatically (about three to four times longer than a pro ring) and there is virtually no chance of popping out of gear making for a much more streetable set up."
i have a g force t5 syncrod......it would be better for your street/strip use
