I have the tremec 6 viper tranny in spf 1837. I haven't had any misshift problems. The gate is narrow but the shift is clean. I am not the best power shifter but with these cars being so short coupled I am not so sure power shifting is all that advisable from 2nd to 3rd. If your power shifting from 4th to 5th your out of my league so no comment. The 6th gear is a great overdrive. My diff is 3.55 and with the 6th gear we're turning 1200 rpm at about 70 mph. It really extends your range on these small 16 gallon tanks.
