It's for a 1991 oldsmobile 98 regency elite, front wheel drive, top three bell housing bolts cracked, and broke off. Also, it's an aluminium bell housing. Thanks.
Sounds like someone did not replace their motor mounts when they should have. Well you can take the trans out and replace it or take it out and go to a machine shop and see if they can weld it back together. Not sure if you can just get another bell housing. GM guy`s would know better. Either way , you have to pull the trans. Unless this 20 yr old car is in great condition, I would reconsider spending more than $300 on it
