I am rebuilding my 47rh transmission, for which I don't really know the history, and in the teardown I have found, among the frictions that look darn near brand new, some things that look like they've been upgraded. I'm getting ready to take apart the valve body for a thorough cleaning and inspection, and I had planned on installing a shift kit. However, before I order the shift kit, and since I have been finding upgraded parts all through this thing, I wonder if a shift kit is already installed?
I doubt that it is, because I had trouble with hard shifts into overdrive during the winter months, prior to the truck warming up fully. This wouldn't be an issue if I allowed the truck to warm up in neutral instead of park. This leads me to believe that a shift kit, which would allow fluid circulation while in park, was not installed.
However, I do want to make certain. So are there any telltale signs of a shift kit being installed? I know what the stock valve body will look like inside, I just don't know how to identify if the shift kit is there or not. Any tips?
