I own 1993 850 GLT and today I was drive and the car did something and the Mode "W" engaged and started flashing. I try to shut it off with the push bottom but it is still flash. The transmission seems to shaft without any problem. What is it? and Is is going to cost a lot of money to fix?

Don't forget, your car has an onboard diagnostic box which will tell you what the trouble codes are. If you don't know how to read them, see the section under 700FAQs.

If the car is shifting OK, you may just have a corroded or dirty switch.

Try "rowing" the shifter lever from Park to 1st gear about 50 times or so, moderate speed (engine off, of course !!). It may still flash the next time you drive, but frequently for me, the second time you drive it, the flashing stops. Seems like it takes at least one "running" for a cleanup rowing to have an effect on the flashing.

If it ever gets to the place where it's actually starting out in 2nd gear (Winter mode), that's more serious. You can't let that go on for too long, you'll burn up the tranny. Same rowing solution often seems to work in both my 854 and my 964. It's been doing it intermittently in both cars for three years, and I haven't replaced a PNP switch yet (thank God !).

Typically the "PNP" (park,neutral,position) switch fails that gives you the symptoms you describe. Unfortunately, yours is a '93 which is reason for concern given the high rate of transmission failures on '93s. Start by reading fault codes at you DLC port A1, and be optimistic that it is nothing more then a failed PNP switch.
