New problem when I went out today if I rev it up to 4k or so it takes like 10 seconds to come back down.
Interesting problem and not seeing it makes it tough but if one was to speculate on a few things as it may be the same problem or more than one.

How is the idle, RPM's cold and warmed up and is the idle pretty smooth?

Sloppy Linkage is most likely the shift bushing but by your description it is really sloppy if you can't select the gear you want. My bushing is gone, new one coming Friday. I can still select any gear but if the selector is in the 2nd slot, start off is 1st, pushing straight forward but not allowing it to go left into the D slot it won't come out of 1st until you do allow it to go into the D slot. Maybe the bushing has been gone for so long it's worn the linkage as well. Bushing is $ 1.95.

Idle not coming down quickly enough can only be a increase of air intake, either a vacuum leak some air source or the throttle body might be sticking. Pulling the air box you can see what's going on there. 10 seconds is quite a long time, not so sure if even the modulator vac line disconnected and not plugged it would allow enough air, it's quite small but possible.

Since it's now blowing WHITE smoke, you should warm up the tranny and check the fluid level. Since you drove 1500 miles one would think if the modulator is sucking fluid it should be down. Keep in mind, you can check the fluid after only 3 mins of running but you have to look in your manual and it will tell you how far below the min line it should be for your model. Or get it hot enough ( drive a few miles ) that the dip stick is very uncomfortable to handle and compare against the full mark.

Pull the vac line off the modulator and see if the White Smoke stops. I was also wondering if sucking Trans Fluid, does it foul plugs and or how much before you would foul plugs. You could also do a test of plugging the vac line and unplugged to see if it comes down to an idle normally.

Of course check your oil level as well assuming you checked before you left to come home you will know if it is burning oil as well. And check the plugs.

That's about it from me.
Let us know what you find.
