When I drive sometimes I miss 2nd gear... I will get up to maybe 20 mph and then the engine will just rev not shifting at all. Sometimes it does shift, but it feels like it pulls hard. Sometimes it will take a good 2 mins until it shifts into 2nd and I will get stuck on traffic

I havent check any codes or done any work to the car so far, it's a 1998 GTP with 130xxx miles on it.

Any help will me appreciated.
