The good part about these transmissions is that any junk just falls to the bottom of the pan. Light stuff might wind up in the filter, but that's it. With the rotating internals inside their own chamber, there's virtually no risk of a piece of plastic making it up into there. As I said in the PM to you, you are welcome to the trans. We live in the Florida panhandle, and will come up through Atlanta., There is a route we could take to go through Greenville, SC, but that is as close to Columbia as we will get on this trip. Let me confirm I have a spare shift valve. If I do, pay for the shipping, and it is yours. It will take at most 2 hours from where you sit now to getting that car ready fore the Rally. I think all involved would prefer to help you make it there.
