weird transmission problem

[jade2ghost]

i got a 440 hooked up to a 727, the car runs fine shifts good so my problem is that when im driving sumtimes my car throws itself in neutral, the weird thing is that it only does that when i turn right:angry1:, bt if im already in first gear it doesnt do it, i have a shift kit, a stall converter, valve body so im not sure what it could be, had the trans was rebuilt a few years back, and ive checked the fluid so any1 can help im all ears thanx

Just about has to be a motor mount / linkage issue, thinks I

Those mounts are the first thing I would check, lube up any cross shaft bushings as well
