A Barton shifter & Redline D4ATF in the tranny solved all my problems.
I have a 2013 Boss 302LS. I took it to the track at Motor Sports Ranch Houston a couple weekends ago. There were 3 other 2013 LS there and all four of us was having trouble going from third to fourth after a few laps. It was extremely hot and as soon as the transmission heated up it was almost impossible to get it in 4th gear. I was also having problem going down to 2nd gear. The car is completely stock. I do not normally drive it on the track and I think I will just change the transmission fluid to some good Royal Purple and live with it. I also still have the stock shifter in the car. On the street I have had no problems shifting.
I had my 5th gear syncro go at about 5000km, before that had constant annoying lockouts at anywhere close to full load shifts. Put in new complete set of syncros in and added a MW shifter with different oil. Not had a single problem since. Still love the car but Ford should have done the job right from the start. Strongly recommend you change the shifter on these cars!

Also - for me to, when I moved my seat closer, my shifts are pretty spot on.
Spoke too soon. Had 3 to 4 problem at drag strip. Had to wait about 2 seconds for the revs to drop before trans would shift.
Installed CHE , K member and torque limiters that will supposedly cure this.
Haven't tried out yet , but, will update.
The torque limiter did not solve the lockout at the strip 2nd to 3rd to 4th.
Guess I'm an easy mark for aftermarket stuff as I put in a Blowfish Trans Support as the next try.
Won't be dragging till next spring, but, may go to some back road to try.
High RPM lockout is clutch/pressure plate related, not really shifter related.
If this is so, why doesn't it happen with all gear changes , only some (i.e., 2-3 & 3-4)?
Where in FL are you located? Also how many miles on your car when they replaced the clutch?Clutch pedal stay out, dealer replaced clutch/pressure plates/slave. Warranty, and no issues since.
5th & 6th gear grinding, dealer just ordered all new parts/syncros. Waiting on parts to install. Warranty, Parts ordered on 16 Feb, just notified that syncro on back order until 10 March. It would appear many issues if back ordered for 3 weeks?
