I recently replaced the blown motor from my 87 with the same motor from an 89. I changed over the harnesses and fuel rail among other things. I also installed the A/T transmission (A340E) from the 89. The car runs and for the most part the tranny shifts properly. The O/D OFF light blinks when O/D is on but not when it's off and it only shifts through ALL the gears when it's warmed up. What pins in the diag box do I jump to find the code? Can this problem be fixed? Any help would be greatly appreciated. Thanks in advance.
