So i had an 07 tl that was in very good running condition…. But the frame was bent from a previous accodent. So i decided to buy a body and drop the drivetrain in ….. turns out i bought an 04 and had to swap the cradel and all ….. well long story short … igot it in and it went into all the gears while sittng still …. No engine lights …. Only the triangle ! Light …. Let it sit for about a week and a half and now the trans will not engage into reverse and drive is delayed …. Help please ….. does any one have the wiring diagram for the 07 and 04 ecm
