Have a tranny problem

[jp.maritz]

My 07 Tahoe Z71 not a 4x4 has over 200 000 miles on but runs like a clock, have a Blackbear 93 tune and very recently the tranny is starting funny business. When you come to a stop and keep on the brake like at a light it seem like the truck just wants to keep edging toward... Kind of giving this jerking rocking type motion, put it in neutral and smooth as silk. Other that that it shift smooth... Been running synthetic oil since day one in engine tranny and rear end. Any thoughts?
