Diagnosing this will be subject to a process of elimination. It could be the radio, blower motor or any other accessory particularly ones with moving parts; Try switching those off and try to note when this problem occurs and what is on/whatyou are doing. Something is getting hot causing the smell so it will be a situation where the accessory will have to run a while before doing it. It is a possibility that there is an electical curcuit overheating, but less likely. Lets rule out accessories first and give us an update. GL

SOURCE: Can't shift into reverse ( manual transmission )

I have the same problem on my 2005 cts. The shifter fork has two rubber bushings that attach at the transmission that break or give way. I assume they did this for a softer feel and to avoid vibration but it leads to the selector not engaging well when you go the extreme direction of reverse on the shifter as there is too much deflection. I replaced the bushings with washers as spacers and it seems to work as a "McGyver" fix. I do intend to get the parts needed from Cadillac to restore it to factory standards. Hopefully they have the parts. To fix the problem you have to go under the car. To get good access you have to disconnect the exhaust and the driveshaft. I did it without this and just tormented my poor hands but I wasn't willing to do all the other work while in my driveway. You simply take the clip holding the fork shaft onto the transmission selector end off and slide the small shaft out. I also took off the shifter side of the fork to study the thing a bit better. That takes a 13mm and a small allen wrench, 4.5 or 3/16, can't remember. Then replace the bushings or do as I did and stack some washers so as to get rid of the slack between the inside of the fork and the gear selector on the transmission. Assemble and try. If you have as good dexterity and tenacity at your fingertips as I do, you'll curse the day you attempted doing this without taking out all the other stuff. If you don't, take out all the other stuff to make room for your hands. The space is very confined. Good luck.

u have a leak in the heater core the oily smell and mist is anti freeze sounds like a small leak because usually u would have a wet floor if it was large -two choices check and repair as necessary the core or can use an additive with a stop leak they usually work well on small leaks

SOURCE: Has no reverse. Will go

Your transmission is bad. You need to replace it soon if you are still driving it. At any moment you may lose forward and only have reverse (trust me it happened to me and I was dumb enough to drive it seven blocks back home in reverse).
