2006 Transmission won't shift. P0743
After having my trans go out on my 2006 CVPI 140K; I swapped the transmisson for another from a 2006 CVPI with 65kmi and now it drives but wont shift gears.
Here is the list of codes i got P0743, P0740, P0748, P0960, P1000
Double checked all the plugs and fuses and all were good. Cleared codes and they come right back.
Any place I should look next?
Thanks all again!!
