Will a 4L60E out of a 99 Tahoe work in a 93 Blazer Full Size? The electrical connection appears the same but we are hearing that the 99 may have a lockup function which would require an additional wire in the harness.
We plan on using the original transfer case from the 93.

Do you
have the same problem?
Yes
No

Nope, 93 is OBD1 and 99 is OBD2 wont' work as you don't have the computer or trans module to run it.
