Also known as the L83.

This is the manual transmission from 1984-1988. It’s a Borg-Warner Super T-10 with a planetary overdrive attached to the tail shaft housing. They are ok transmissions, but complex.

The automatic from 1992-1993. The same as the 700R4, just has a different name. Either way, they are junk. There are some minor differences on a year-to-year basis, but the units are essentially the same.

1994-1996, the 4L60 with Electronic Control. From what I have seen, it seems a bit more durable.

4-speed overdrive automatic transmission from 1982 to 1991.
