Locked in gear

    Hey everyone I need some help before I tear the truck apart!

    My 86 GMC is stuck in gear (I think it's locked in first gear 4wd low, or possible 2nd or 3rd) it's a 3 speed transmission. Before I tear the thing apart, anyone know another way I could get it unlocked?

    I'm getting tired of this truck, it's in excellent cosmetic shape except it was used as a plowing truck before I bought it (for roads, and a parking lot)... gas tanks replaced, axle, hydraulic clutch, and many other things have been replaced on it.

    thanks

    Does the shifter move at all when you try to pull it out of gear? Or does it feel like it's disconnected from the tranny,like it just flop's around and doesn't seem to do anything?

    if the vacum line to the trans. isn't connected the trans will not shift. Check that before you do ANYTHING. unless you have a full manual valve body

    It's in gear, but it's like it's in Neutral... and just flops around.

    OK, since it just flop's around it may have just broke the "finger" off the end of the shifter handle.It's not uncommon for the SM465 tranny's (which is what should be in your truck) to do that, especially one used for a plow truck. I'd pull the shifter up out of the tranny and check it out first.If you get lucky and that's all that happened then you just gotta cross your finger's and hope you can get the broken piece up out of the shifter tower too.

    All fixed.. the forks were fine. The thing had very little transmission fluiid and it looks like someone (previous owner) had messed with it judging by the appearence of the gasket, and it appears they didn't do a good job.

    Had to cut the metal around the shifters to get into it... and what a pain in the ass to re-allighn everything!

    Oh well.... It's all better which makes me happy.
