The problem with high RPM shifting is the clutch. Go to BossMustangsOnline and you'll read all about it. The pressure plate is not letting go completely, making the syncros try to mesh under less than ideal circumstances.

BTW I totaled my car at the track and got another one just like it. It has high RPM lock-out. I'll likely get a Centerforce or McLeod RST or RXT for it.

Arrow Re: High RPM shifting problems

The issue you are having is your mounts are too soft, get some stiffy rear differential/tarnsmission mount.

What's happening to your shifter at high Rpm is that it is shaking vigorously, you should be able to easily shift it though and this is not something you should take it to the dealer. What are they gonna do, rev your car over 6,000RPM for 30 minutes and come back saying everything is fine?

The problem I found with any diaphragm clutch is after hard use The fingers get to soft and the only way the clutch will shift clean is if you push the peddle to the floor and delay the clutch on the floor this will give the clutch time to release! This don't make for a good fast shift but to will allow the tranny to shift! The clutch should be replaced with a good long style clutch if you want to power shift!

Re: High RPM shifting problems

The information you have be situated given is all true however. You might precise it with a clutch alteration (could have a stretched cable), it power have a shifter issue (could be external at the top of the tailhousing or an internal problem) or you could have ground away the syncronizers and the gear's engagement teeth. These issues affect all manual transmissions, no matter what brand.
