The 89 does not have a 4L60E. The 4L60E wasn't used until 1993. The predecessor to the 4L60E was the mechanically controlled 4L60, which itself was just a rebadged 700R4. It will not be compatible with a 97 model year vehicle.
NO it will not interchange. Even thow they are both 4L60E transmissions the bell housings have a different design. Won't work.
Yes
NO it will not.
That would be the 4L60E and yes it will work. The 4L80E will NOT work
Will a 1996 4l60e 4x4 trans fit in pace of a 1995 4l60e 4x4 trans
That would be the 4L60E transmission.
That is a 4L60E
That would be the 4L60E transmission.
4L60e / 4L65e
That would be the 4L60e transmission.
4L60E / 4L65E transmission.
That would be a 4L60E transmission.
