Hey James. I am pretty sure this happened before the drop-in K&N. It's bone stock otherwise. I am getting really frustrated with the car. Its impossible to drive it normally. Almost every time I shift I am cursing at the results. It feels like I have to slip the clutch way too much to get a smooth upshift. At this rate i'll need a new one in 2 or 3 more years!
I'm thinking about getting rid of it but this is the car I want and I want to keep it for a long time. I am going to try swapping the gear fluid to the Extra-S as soon as possible. I might also want to do the SPT trans mount. I need to do more research and ask around about it and decide what the best upgrade would be to counter this issue.
I am taking the car in for a slow tire leak tomorrow. I am going to have them check the fluid in the diff but I don't really trust this dealer to do much else.
