It is an IDI. They all were until 1995. If there is on OD OFF button on the dash or the end of the shifter it's an E4OD. If there is no OD OFF button it's a C6. Another way to tell is the sticker in the driver's door opening. Under TR there will be a letter. E means E4OD. I think K is C6, but I'm not certain. The only two possibilities are E4OD or C6, so if it's a letter other than E it's a C6. Also, 1989 was the first year for E4OD, so if it's an '87 or '88 it's a C6.
