I've got a 99 Mustang GT with the T45 in it. I paired the engine and transmission recently and put it in the car, with a brand new clutch. I've been driving it for about 3 days now, and it was fine at first but now the clutch is acting weird. If I just push it in all the way, it's fine, but if I slowly push it in, it 'catches,' and takes a lot more effort to push any further in 2 spots. It's only really noticeable when I'm taking off or reversing. It might be something simple, but I don't know much about a manual transmission setup. What should I look for?
