Re: 89 electra park ave engine noise 3.8
oh ok, I have zero experience with transmissions.. I have done timing chains before and such but I have yet to open a trans... It does slip a little from 1st to second..

Re: 89 electra park ave engine noise 3.8
You really cannot do this on your own without the the proper tools a way to support the engine, remove the ft suspension subframe and so on, any yard has interchange books that will tell what interchanges. You cannot pull the trans out in the yard, I assume they have these components shelved.

Re: 89 electra park ave engine noise 3.8
Changing the chain is easy:
 GETTING to the chain, on the other hand, is an all-day job and then some. I would not even attempt it on the vehicle, so plan on removing the transmission. That will include restraining the engine and dropping the front cradle, then removing the transmission. FWIW, the last on I did I had the wrecking yard remove the core (for rebuild) while the car was in their yard. They do it all the time.

Yikes, you and your pics again, nicely done, we certainly agree on the what is required here, but we really don't know if in fact this is his issue. Not a job for most dyer's.

Re: 89 electra park ave engine noise 3.8
Perhaps it IS the other chain.
