Just yesterday my transmission started acting very strange. Everything was fine, but suddenly every shift started to become extremely hard. In fact, the shifts (between any gears, but mostly 2nd to 3rd and 4th to 5th) are so hard that I feel the entire car jerk forward when they happen, almost as if something is trying to rip itself out from the bottom of the car. Also, I noticed that the upshifts are not happening at the same points as they used to (upshifts are happening later than they should, then finally when they do it's a really hard shift). This seems really dangerous. It also just started happening so suddenly, and now it's like that every time I drive. I tried doing the shifting myself with tiptronic, but the shifts are still really hard.
ATF level is okay; the dealer replaced ATF last September.
Sorry if I'm not being detailed enough; I tried reading the FAQ and some other posts but can't really understand what can cause this. If anyone has seen this problem or knows what might be happening, please help me. I'm afraid that the longer this goes on, the more chance it may permanently damage something. Also I'm not sure but I think it might be "heat" related, since it doesn't happen just when I start driving, but is definitely there by the time the engine temp is up to 190 degrees (the normal operating level)
Also, my car does have a cold air intake. Not sure if that might have something to do with it. Thanks for reading.
Edit: forgot to add, it's a Jetta '02 1.8T with 5-speed tiptronic
