I have been experiencing some disturbing downshift problems with my 850 Turbo automatic. After a hard run, the tranny will downshift late when shifting down to second and first gear from fourth. This oftentimes results in the final downshift occurring after the car has completely stopped, although it sometimes occurs after I push on the accelerator to leave a stoplight. The effect is most pronounced in "sport" mode, less so on "econo" mode and does not seem to happen when I run in 3 speed mode. I also have experienced hard shifting to reverse right after this happens (maneuvering for a parking space, etc). I had the tranny power-flushed a couple of thousand miles ago with Volvo fluid, so it seems unlikely that it is the fluid (which looks pretty good when I inspect it on a white rag). Also, there are no error codes showing up (verified by the local Volvo dealer). I could definitely use some help from the transmission experts on this board to diagnose this problem. I have been seriously considering some performance upgrades that will presumably increase the HP output of the engine, but I am loathe to go too much farther until I know the nature of the transmission problems-more HP could be the proverbial straw that breaks the tranny's back. Thanks in advance.
