At 207,000 miles, I'd say you're in for a complete rebuild. It was probably the fluid change 3000 miles ago that did in the clutch packs, they don't take kindly to fresh fluid if they've gone that long without a change. You could do a bandaid patch & replace the front A-pack and pump but the rest of the trans is going to need attention soon. Time to contact Kirt Koeller. Actually, one of the best deals for a rebuilt trans is thru the dealer, labor isn't that difficult if you do it yourself. An indie might charge $500 to swap trannies. Might as well pony up the bucks for a new or rebuilt torque converter since if the trans is making noise like you say, there could be lots of debris in the old torque converter & you don't want that migrating into a fresh trans.
On the bright side, this would be a good time to convert it to a 5-spd
