OK so its 5 months later. I replaced the thermostatic element that I found in the drain pan the day I posted this question back in November. I have had an intermittent clunk since doing the fluid/filter change and having problem with the element falling out of the pan. The clunk occurs once in while when leaving a stop sign from a dead stop. Switch from brake to gas and get a bit of rev-up then a clunk. The transmission seems to shift perfectly normal other than this issue. I mentioned the issue to a buddy who has connections with a shop and he said this sounds like a problem that could be related to that element being installed incorrectly. I'm as sure as I can be that I put it in right but now I'm second guessing myself.
Any thoughts here as to the installation of this piece contributing to a slip/clunk as described? Thanks in advance.
