In reading this, thread, below the symptoms I'm experiencing are nearly identical. The link for the HardShift Solution in the last post doesn't work for me, though. Mine is intermittent to where I may drive for over an hour and never experience a single hard upshift. The next time, though, when it's warm, I might have every shift as it slams into gear.

TCC was replaced about two years ago. Is Lucas the thing to try, at this point? Bill, you mentioned a shift kit, too. I'm not opposed to replacing the TCC again if that's the best solution. If so, what is the best brand out there, to date?
