Just had it fully rebuilt was what I was told, supposed to be a good shop around here, I think I have the transgo kit around here somewhere but could not find a shop that wanted to install it. this was the first trip on the rebuild about 1,000 miles, I am not sure about the sensors being changed, do you know just what controls the shifting? is it separate from the transmission? I pulled this transmission out myself and took it to the rebuilder then reinstalled it, only a one year or 12,000 mile warranty, I am past that.
