I dont know what to call this part so I will describe it. It is the metal housing on the passenger side between the transaxle and the cv shaft and I have a leak between this housing and the transaxle. I would like to know what it is called and any advice about changing the oring or gasket. 4t65e

 

That would be the diff cover. There is a seal in the diff cover that seals the axle and also a rubber o ring behind that cover. Figure out which spot it's leaking from and go from there. The seal can be changed with the axle pulled and diff cover on. The rubber o ring you need to pull the axle support the trans with a large flat board and a jack and unbolt the diff to engine bracket and then the remaining 2 diff cover bolts. Both take a little time but are fairly easy to do. Anymore questions feel free to ask

 

It's leaking atf that sound right?

 

Yes it would leak atf (trans fluid)

 

you're the man buddy

 

No problem. Glad to help!

 

how much would a mechanic charge for this?

 

I honestly don't know what a mechanic would charge. If you have some tools and an afternoon you could tackle it I'm sure. I could even give you a walk through if needed

 

I can't find the seal and oring to buy to save my life.

 

The o ring maybe a hard one to find and is probably gm only. Any parts store will have the axle seal.
