I am convinced (based on the sampling results taken from exactly ONE TKO installation in my life in my Cobra) that many of these shifting problems are somehow related to bellhousing alignment. I have realigned mine a couple times while having the tranny out for other issues and only with this last installation was I able to get the run-out to under .005. Generally it was around .007-.008. I also used a 303MC pilot bearing this time whereas previously I used the bronze bushings and WOW what a difference. It used to be very tough from 2nd to 3rd at anything above 4k RPMs, coming down from 4th to 3rd or going into reverse. Now its silky smooth at any RPM in and out of all gears. I also now get zero vibration in my shifter and earlier with the bronze bushings there was always some vibration.
Just my 2 cents....
