Im getting a pretty bad vibration from either the trans or possibly a loose engine mount. I have some aggressive cams and it only occurs during low rpm idle in neutral and also when taking off from a stop. Im guessing its the input shaft on the trans since its a newer trans i bought from someone. The last time it was out of the car i did notice quite a bit of play in the shaft, which is why im leaning toward this being the issue... Anyone had any similar issues with a bad input shaft bearing/incorrectly installed one... just looking to re-assure myself that this could be the problem before i go pulling it out.
