    i just picked up a 02 gmc 2500hd for parts!

    the truck is a bit beat up, but over all not to bad.

    the story is the truck only goes forward! even in neutral!
    has NO reverse at all.

    the gut i bought it from and said he had the transmission looked at. he was told the clutches are stuck together.....has anyone heard of this? or can confirm the is the problem?

    Such a young vehicle to be trashed already. Fix that thing and get it back on the road.

    oh well, i was hoping fro a easy fix.
    the truck is going to be for parts either way.
    i was just hoping to have a spare transmission, maybe i'll pull it and have it rebuilt?

    Ya, should be a good candidate for a rebuild. Just make sure that you get that tranny, lines, valve body, and pump flushed VERY good. I would just replace the torque converter.

    yeah, i think i might have it rebuilt for the truck i drive.
    my truck has 166,000 miles. inevitably it's going to go.

    a friend of mine rebuilds tranny's...i talked to him a while ago he said he would cut me a really good deal. i also have a deep aluminum pan i have been saving for when i put a new trans in.

    nothin to be worried about plan on spending around $1500 to have a trans shop do the work.

    Very typical for those 4L80's

    Have you considered slapping in a junkyard transmission? Then it's a small, inexpensive job (relatively) and you end up with a whole truck worth driving.

    it's not worth it.
    it's worth more as a parts truck to me then worth driving.

    my truck i'm driving had 166,000 miles. i use it for plowing and sanding also hauling my 20' trailer.
    i paid 650 for the truck with the bad trans. the parts it offers will keep my truck on the road for a long time to come. also the body is all dented up passengers side door is messed up.

    on top of that i just bought a 97 2500 dodge dam. thats worth fixing. i rather put the money in to that....even though it is a Dodge.... i bought it right. thats the only reason i have it.
