Loud Bang from rear 1-2 shift
My car has been out of commission for the last month or so. Just got it on the road last weekend, sure beats the 4 banger Sunfire beater I have been driving.. Anyway.
Tonight on my way home from work, there is a spot I have to do a U turn on a busy road. Got some room, and floored it. As the car shifter from fist to second, the car used to make the tires bark, well tonight instead I heard a loud metal to metal bang noise... My tranny does have a stage 2 shift kit.. So I'm wondering if I broke the rear gears, or something?
Anyone with any thoughts on the matter?? Thanks

If I keep my foot out of it, IE drive it "normal" it is fine. If I floor it from a dead stop it makes that bang noise and "feels" like its slipping for just that moment, then it seems fine, until it shifts, then it does that again...
I just went out for dinner and a test drive. It seems that the noise and the "bump" I feel when this happens is only on the passenger rear. Could it be the axle slipping???

i put a new rubber mount just about every year. it's a PITA! my car is on it's third transmision. oh well... forgot how many mounts i killed.
Tsk, tsk, tsk! You coulda bought a poly mount by now with all the money you've spent on the worthless rubber ones! I managed to break the rubber ones with my anemic 305 TBI. Put a poly one in and haven't had a single problem since. Definitely a good upgrade!
After replacing my rubber one with a poly one, and not liking the vibration, I went back to a rubber one. I broke it within 500 miles (WOT tuning
)
I replaced it with a tougher LS1-style mount. Let's see how long this one
lasts.
