Drove it last nigh and tonight. 70 miles round trip, both nights. Good news is that I can still rebuild a valve body and make it work. Bad news is that it didn't fix anything, which is what I expected after the shards of band in the filter. Looks like I'm going to pull the 93 300E trans, put my valve body in it, and see if it's any good. If that works, I'll live with it. If it's wanky, I'll get the original trans rebuilt and swap it out later.
