This is a very common occurance with our cars.
Terry Haines...the genius that he is...came up with this fix.
I've had two '98 CSVTs and both would grind when shifting into 2nd gear in the Winter...
This fixed them both.
1) Start your car and let the idle settle to it's normal level.
2) Tap the gas so that the engine revs to 2K
3) Repeat #2.
That's it.
I do it every morning and no more grind.
