Working on a 1997 GMC Sierra K1500 305 4l60E. I had the code read and it said the TCC solenoid wasn't disengaging so I bought what gm calls the tcc solenoid and it had some electrical backwards, so I decided to put the old vavle back in because what I bought wouldn't fit correct. I also figure now that it ain't the solenoid that needs replacing. Anyways, after I pulled it out of the shed it continued to shift like crap, hard shifting, almost stalling when stopping, no power because of early shift and no tcc slip to allow for acceleration as well as not unlocking when hitting the brake. After about 15-20 miles of pulling the trailer(approx 4000lb) it started to work PERFECT. All shifts were smooth, correct shift timing, it never slippeed or anything. It worked just the way it should all day long. It does this everytime I pull the trailer. No matter how terrible it was shifting before it snaps out of it and acts perfect. It will work good after as well for a while but reverts back to hard shifting. It might randomly start working properly for 10 minutes and then start shifting too early and too hard again. It really seems to get worse in the cold. I've replaced the fluid twice. The fluid didn't smell burnt at all and was slightly darker red then new fluid after 25000 miles. The magnet had about 1/8" of crap on it the first time and a bit on it when I changed it again after 2000 miles. When it's not shifting properly it will shift from 4 to 3 but it won't unlock first, it just jumps to thrid with a hard shift ,and when it shifts back into 4th it doesn't shift into 4th with the tcc unlocked and then lock up, it just stays locked and shifts. The transmission has a 11"x16" external cooler without a cold weather bypass.Sorry for the long speil about this. I just don't know what's wrong with it anymore. I can't figure out what is going on with it that it works so well with the trailer but runs to badly without it. Thank you for any help.
