So, after an engine rebuild at the co-op, we're experiencing a inordinately high (according to our gauge)temp reading -- running at about half, rather than the 1/4 it was running before the work. Oddly enough, it seems to drop when I accelerate up a hill, and climb when I run steady. I'm currently thinking we're having some sort of transmission anomaly, where, perhaps, our third gear is struggling to shift, causing the engine to heat up, ad when I finally push it to forth, it cools down (just a thought, of course). We're about to jump off on a cross country trip, and further diagnostic at a gmc specialist seems overkill at this point. Anyone have any ideas?
