I'm replacing the leaking rear trans oil seal and installing an aluminum D/S in my '91 RS (700 R4) while I'm at it. I got a seal kit and with the kit comes the case extension bushing, the round babbit lined bushing the yoke rides on.

How do you get this piece OUT of the trans? GM probably has a tool for this, but how do I get it out?

Thanks all

 

If you take the ext hsg off, you can use a cam bearing tool. Trans shops have a puller that they use without disassembling anything. You can probably "rent" a bushing knocker from Auto Zone or that type place.

 

Careful use of a large, blunt tipped screwdriver is all I use. Just pry it out, don't scrape the inside of the seal seat.

 

Thanks guys. I just left it in there. Too much hassle and the one in there looked pretty good anyway.
