Hey everyone im new here! Bought my first GTP the other day and have a few questions about it. 98 GTP with 120,xxx. I have already changed out the supercharger oil and i am thinking about a few basic modifications.

The first being a trans-go shift kit.

^That is the cheapest i can find it but i want to make sure it is a legitimate shift kit for our cars?

Also i found these but im not sure if they are worth it?
