I have a question about my transmission. I am sure this has been asked several times but I have searched to no avail. I have an 89 RS with the 2.8. DOes anyone know what auto transmissions were offered that year? What I am wondering is do I have the 700R4?

 

Yes, the 700R4 was first offered in 1983 and became the only automatic available starting in 1984. That includes your '89. But you have a V6 version of the 700R4, which has less beefy parts inside it, and a different bellhousing bolt pattern compared to the V8 version of the 700R4.

 

Thanks for the info. So if I planned to rebuild it I could get one from a v-8 and put my bell housing on it? Then have a beefier trans behind the v-6.

 

The bellhousing on a 700R4 is part of the trans. It is not removeable like on a manual trans.

You can build up a V6 700R4 to have the same strength as a V8 model.

 

I build these things everday Just like KEVIN91Z said you can beef up the V6 pretty easily. The input sprag and low reverse sprag are smaller, has less clutches in the 3-4 clutch pack, some really early ones had one less in the reverse input clutch too. Anywayz you can do about anything you wanna either way. Good luck man!

 

Thanks for the info. This is a great forum!
