Shift kit and traction control?!?

Impala owners of the free world:

Do any of you know anything about traction control messing up, disabling, and/or damaging a shift kit (or perhaps even the tranny)...

I recently had a shift kit installed to eliminate hard (up)shifts (P1811 error code)...There was a noticeable improvement in the shift (crisper and quicker) and no more "hard upshifts", plus the tranny shop cleared the code....

Long story short, it recently snowed here and I found myself and the car stuck (for a few minutes) in snow (3 different occasions the same day...all 10 or 15 minutes apart from each other...)...Anyway, I forgot to turn of the traction control....and the the wheels spun like crazy and the traction control kicked in...

Now shifting isn't as crisp and quick? Did the traction control mess up or damaged the shift kit by any chance?

Please advise & feel free to read my other posts:
