I went back and read Clinton's position, which was that the concept of the US pivoting to the Pacific Rim vis a vis trade was critical but that TPP lacked some additional measures she wanted (ex. stronger measures against currency manipulation).
I don't think Trump ever articulated a cogent policy position on TPP at all. He did have plenty of his usual free association ranting, though, like:
> "And the Obama Trans-Pacific Partnership and fast track are a bad, bad deal for American businesses, for workers, for taxpayers. It’s a huge set of handouts for a few insiders that don’t even care about our great, great America."
