    I have a 1994 chevy 2500hd with an auto trans and have an intermittent shifting problem.
    It happened 2 time since I bought it 6 weeks ago.
    It does not shift out 2 nd gear. It will shift in rev. When I shut it off and let it sit for a while
    it will work fine No slipping and no issue. I have used it for about 1000 miles and it happened twice. Trans problem or electric issue? Please help

    94 chey trans Trouble, 2

    I'm also having trans trouble, it started when I went through some rough weather, very heavy rain. I first noticed the speed-cable acting funny, it was bouncing up and down. Then when I came to a complete stop, it wouldn't shift gear, from 1st - 2nd. After it sat awhile, everything was fine. I took it to a tranny shop and the problem stopped, now my Altenator went out and it's doing it again. Of course when I took to the shop again, it wouldn't act up for them. Now, it acts up in the morning, it used to be when the truck was "warm", like after a good run down the highway. Can anyone tell whats wrong with it and how to fix it before I put it out to pasture and put it out of my misery?????
