Tranny Question
We can answer your question by more than one way. The first way is for you to give us the transmission code off the door tag. E indicated you have the E4OD. U Indicated the AOD.
The other way to determine is by looking at the shift pattern on the cluster. P R N OD D 1 indicates you have the AOD. P R N OD 2 1, with the O/D button on the dash indicates you have the E4OD. If you have the same pattern with no O/D button, you have the C6.
The other way to determine is by counting the number of bolts on the transmission pan. The E4OD has 20 bolts, the AOD I believe has 17, and the C6 has 14 I believe. I do know for sure that the E4OD has 20 bolts.
