I shut my 1991 190E off on Friday night and all was good. On Monday, I started it up and it will not upshift at all. Not only that, it freewheels when I let off the gas rather than using the trans to help the braking. I saw previous threads that this might be the kickdown switch but there was no mention of freewheeling on that thread. Does it sound like the kickdown switch? Or is it something worse?

Thanks.
