E40/T42 swapped vehicle, disabled the P0068/121 tests, 13 pin valve body, & I have no clue why this is happening. The OS is from a 05 corvette & I'm told the trans is out of an 04 GTO. It's in 4th gear by less than 20mph, & I can't force a lower gear cruising with the Bi-directional controls, they do nothing. Any help would really be appreciated.
