Thank you for your response! After looking over the car, I've noticed that there are different bolt types, compared Volvo and BMW. I wanted to make sure that I have the right sets to help make this repair job easier.

You mentioned this bushing between the input and output shaft, if it falls apart, can it lock up the transmission, making it very difficult for the car to move forward or backwards? After further testing, I've come to realize that the differential just needs fluid and no repairs are necessary for it.

This bushing, however, is that a simple fix? Or will I need to drop the transmission to replace it? When the car started having issues, I would have to say that the fast tempo Zzzzz sound was made, like a very heavy rubbing noise coming from directly underneath of my floorboards.

The little rubber bushing in the shifter has come out, so I am replacing that along with the repairs necessary to get me back on the road. I'm trying to use what knowledge and background I do have with cars, to make this job less costly.

Thanks again for any advice you can give!
