Tranny ID on '89 GW

Post by MReno »

So the top of the transmission (as seen from inside of vehicle with carpet and transmission cover removed) indicates 577? However this does not align with any of the transmission models in the Full Service Jeep Manual?

Any idea what transmission is in my Jeep or where I can find the actual transmission model # if the 577 is not associated with the transmission model?

Thanks.

Pretty sure the 89s all had the TF727.

Snap a couple of pictures, we should be able to confirm if it is a TF727.
