: Check Engine Light

10-07-12, 12:23 PM
Coming to work, accelerating at 30 mhp, let off gas petal, heard a noise I think from tranny area, check engine lite comes on immediately, still drives and shift normally, Is there any place you can read check engine lite besides dealership? Are the trannys sealed for lifetime fluid?

Autozone, Advance, etc., should be able to scan your car for codes and tell you what is throwing your SES light.

See my post, Whine on 2008 STS V-6 (http://www.cadillacforums.com/forums/cadillac-sts-forum-2005-through-2012/271610-whine-2008-sts-v-6-a.html). It was coil pack failure that set mine off.
