Thanks for any help up front.
94 GCL, 5.2. Motor changed out a couple of years ago. (Salvage yard swap, lesser miles on new motor)
I think the trans was swapped as well, I don't recall for sure.
Trying to determine my transmission.
Driver's side, ride above the pan connection stamped:
PK5211831217366446 (The best that I can tell)
Further down, near the tail a sticky paper bar code tag with the numbers:
Bottom line, I don't have overdrive. Everything else works, no overdrive anytime.
Tried self diagnostics but nothing comes on the light above the OD button.
