Hello New member. Heard about this sight many times , then Tuesday at the Hot Rod Power tour at Metro Park in Detroit mi a guy recommended to join this sight for info as well as entertainment. I have a 1967 Nova I have owened since 1992 . I just Finished installing a 2007 Trailblazer SS drive train that had only 17 Miles. It is a LS2 stock with Stainless Works long tube headers GTO oil pan, intake and Camaro Belt ,water pump setup. Stock Front Clip. The trans has a Yank SS 3600 stall converter. I changed the Sprag to a Borg Warner unit and converted it to 2WD. I used a GM Performance Harness, E67 Computer, throttle pedal, also a T42 transmission module and harness from the Trailblazer. My only issue now is I have no communication between both modules.This causes the Trans to go failsafe which boost the pump pressure to maximum. OBD2 code ou100 . That I am trying to sort out.
