Teleporter script has an error?

I have 2 teleporters. I just need 1, because they are basically the same thing:

script.Parent.Touched:connect(function(tch)
    local trs = tch.Parent:FindFirstChild("Torso")
    local lrm =  tch.Parent:FindFirstChild("Left Arm")
    local rrm =  tch.Parent:FindFirstChild("Right Arm")
    local lg =  tch.Parent:FindFirstChild("Left Leg")
    local rg =  tch.Parent:FindFirstChild("Right Leg")
    local hd =  tch.Parent:FindFirstChild("Head")
    if trs ~= nil and lrm ~= nil and rrm ~= nil and lg ~= nil and rg ~= nil and hd ~= nil then

        trs.Position = script.Parent.Parent.TP2.Position
        lrm.Position = script.Parent.Parent.TP2.Position
        rrm.Position = script.Parent.Parent.TP2.Position
        lg.Position = script.Parent.Parent.TP2.Position
        rg.Position = script.Parent.Parent.TP2.Position
        hd.Position = script.Parent.Parent.TP2.Position
    end
end)

The problem is that I think the joints disconnect when repositioned and makes the player die.

Is there a good method to make sure the joints don't disconnect and teleport?
