Dead battery, long shifts?
I brought my GP into the brake shop so they could finally diagnose the ABS light I've been getting. But, they told me that my car wouldn't re-start, and they had to put the battery on a charger. On the drive out of the shop, My 1-2 and 2-3 shifts were abysmally slow and soft (as in 2-3 seconds to complete a shift), but it went away after a while.
Same story yesterday: my battery gave out after a lot of short drives, and after a jump start, my transmission was acting up again. But, after 25 miles or so, the shifts were nice, quick, and smooth again.
Is transmission line pressure one of those "drivability" things that disappears when your battery runs down?
