So recently (within the last 2 days) my car started making a weird noise kinda like a bad axle joint, but it's only happening with the clutch engaged in second gear. Its RPM dependent and when I push in the clutch it goes away. Its a b16a Sir tranny that I've had in the car since I did my swap a few years ago. I've been avoiding 2nd gear in an attempt to prevent aggravating the problem. With spring break coming up, I'm thinking of dropping my tranny and rebuilding it. I know it needs new seals and stuff since it leaks a little bit and at the same time I'm thinking of swapping in an LS 5th gear for better highway mileage (the car isn't tracked, just AutoX so 5th doesn't matter). From my description can anyone help me pinpoint the problem and confirm that I need to rebuild?
