If these rumors are from people who have done the swap on an 86 then I would be more inclined to say it is fabrication fitment error. I've driven three different cars using the Magnum XL from AM, one of them being my old Roush, and this is the first I'm hearing of high rev shifting issues with this transmission.
Buddy is running 750hp on a 76mm precision with the magnum XL and he has no issues, and that is winding out the 5.0 aluminator out to 7800rpm. I've personally driven the car and did not have any issues whatsoever. Shifting at redline is butter smooth. It is definitely built better than the stock mt82 and is capable of revving just as high.
Maybe its an issue specifically going in the 8k+ range. Up to that level however, my experience with three different magnum XL's have been positive.
