    What kind of transmission do you have? Not real sure on what could be the problem cause i dont know when GM went to the 4L60E.

    Its on my friends 87 Silverado pickup. It looks to be the same as the tranny on my 91 k5.

    My truck had a similar problem. It would only shift out of first if I floored it, and it wouldn't shift until I hit about 4K rpm's. (guessing, but very high). The first time I had my tranny rebuilt it cost $1100, and the second time it was $950. That is worst case scenario. That is a total rebuild w/R&amp;R. It could be something really easy, dirty valve body, screwed up linkage, etc.

    My Chevy isn't broken, its just out of gas.

    does it shift into reverse, neutral, park, and first? if so then its probably ur governor. it happen to my truck and cost me about 20 bucks to fix. just pull out ur governor and take it to a transmission shop and they should be able to put a new gear on it.good luck

    something to check first would be your vaccum lines and modulator

    Governor or intermediate clutch (i think). My TH350 had no upshift because the governor flew apart. It wouldn't be a modulator because you have and overdrive transmission and they don't have one.
