Automatic transmission 2005. 6 cylinder

The transmission has a problem with the speedometer cable, which causes jerking sometimes. When it's cold, it doesn't engage D, but once it warms up, it engages perfectly. When I was in a hurry, I would shift manually: 1-2-3-D and so on. It worked fine with me for about three years like this. I installed another one and kept the old one as a spare, but now I have no use for it. Whoever wants it can take full advantage of the parts, because even its sensors are intact, or if his transmission is faulty, he can take the missing part from mine. Or he can install it as it is, use it and see. But there's what I mentioned—of course, the pictures aren't available, but it's exactly as described. Please ask for more details, for your benefit and mine.
