I have a '95 850 w/ an intermittant transmission problem. When it gets hot after doing some freeway driving it will noticably seem to stick when downshifting through the gears coming to a stop. When starting up after this happens it seems to be in the "winter mode" for a few seconds. The car moves very slowly then suddenly drops into normal low gear with a loud thud and therafter shifts normally. This seems to happen for a few stops then goes away. New fluid makes no improvement. No error lights displayed. The local independent service garage did a tranny fault analysis and found a "winter mode reading". This was cleared but made no difference. The "winter mode" switch light never comes on or blinks whenever this happens. I have tried cycling the winter mode switch on and off when I anticipate the problem will occur and also tried moving the lever each way out of "D" with no improvement. Is there any type of winter mode module that can be replaced or is it time for another tranny? Also what other transmission years will work in my '95?
