    Default C3 automatic transmission shifter

    I am new to the vet world. My 1977 vet has an automatic transmission shifter that moves freely between R N D D2 D1. This scares me when driving. Is it fixable? replaceable? the way it is suposed to work? or really screwed up? Thanks for any help!

    How do you shift at all if it moves freely between the gears? I guess I'm not visualizing exactly what you are describing...

    Do you have up-down movement against spring resistance on the button? The button should be "up" at all times, and you should have to push it down to get from neutral into reverse or park. If the button doesn't work like that, the detent spring has probably broken or fallen off inside the base.

    When I got mine, it did the same thing. The Reverse Lockout tab was broken off the shifter. I took the shifter out and, along with the tab, went to a machinist buddy of mine. He brazed the tab back on. I put it back together. Haven't had a problem since. I couldn't find a shifter anyware. That is why I went the 'repair' route.

    You should be able to find a shifter on E-bay or if not for sure they would have one at Contemporary Corvettes. It's a corvette wrecking yard in Pensylvania. I've bought a few parts from them and the price and service was EXCELLENT!

    I took it apart over the weekend. There was no spring at the top but one at the bottom. It does not push the inside rod up high enough. The shifter aparently is not original. It is a wooden know with wooden button. Should there be a top spring?

    Thanks for everyone's help!

    I believe there's only a spring at the bottom. I have to dig into my console in the next few days. I can take a picture of mine. I might already have a pic from when I replaced the shifter key/plate.

    The flaw in my shifter is that you don't have to push the button down to go from 3 to 2. Just tap the shifter and it's down shifted. This happened by mistake while adjusting the radio. What would recommend Mr. Z?

    Jodie, did you unscrew the ball and check the spring under the button? Does it work properly for Park and Reverse, just not the lower 1-2 positions?

    Thanks for the reply ,
    The shifter works except for the fact that you don't have to push the button down to go from 3 to 2. In fact it takes very little pressure on the shifter to downshift. This happened once by accident when I was adjusting the radio. As I brought my hand back I bump the shifter and damn near went through the windshield. I'll check the spring when I get my car back from the shop.
    By the way who in your opinion has the best stock shifter? Just in case I need to replace the whole thing.
    Thank you again.
    You do on mine have to push the button down to go from 2 to 1
