WAWalker Posted February 6, 2008 Share Posted February 6, 2008 Check all your harness connections. That is the signal that tells the ECU that the car has an automatic transmission. Link to comment Share on other sites More sharing options...
scrapdaddytatum Posted February 6, 2008 Author Share Posted February 6, 2008 ok will do, car is an auto (trans and tcu are out of another car, same year/engine/trim) so there shouldnt be any funny bussiness going on car original trans had broken pump so pulled to rebuild(was not able to) off to check elec Link to comment Share on other sites More sharing options...

idosubaru Posted February 6, 2008 Share Posted February 6, 2008 are you sure it's only got first gear and isn't just running in limp mode - which would be 3rd? if it's in 1st it's not good for very fast, but 3rd is capable of 60, 70, 80 mph. was the transmission removed for the job? give us as much background as possible, if it was i would check and make sure the harness is fully seated and none of the pins were bent.

scrapdaddytatum Posted February 7, 2008 Author Share Posted February 7, 2008 so i swaped the TCU and got shifting and AWD back but now the light is flashing at me again allways something Link to comment Share on other sites More sharing options...
johnceggleston Posted February 7, 2008 Share Posted February 7, 2008 so i swaped the TCU and got shifting and AWD backbut now the light is flashing at me again allways something have you checked for torque bind? if so does it go away with the fuse installed? a bad duty c will cause flashing. i would have thought if it was the duty c it would have shown up with the other tcu but who knows.? try a third tcu, maybe 2 out of 3 would be a clue to the cause..

Skip Posted February 7, 2008 Share Posted February 7, 2008 Please excuse my corn-fused look (scratches his frazzled old bean) Why not just read the code it's telling you??
