It seems automotive industry, at least GM, has wiring issues. Although the percentage is low, it can be potentially deadly. Since cars do not fly, they do not have to meet standards of aircraft. Besides the level of quality parts, they have to meet higher standards of inspection for quality.
I can also say that many others have had same issue with GM vehicles.
Certainly a very thorough check of wiring is necessary to insure it is internal to transmission. Locating the connection pins at the transmission disconnect point and reading for resistance of the coil is likely needed.
I'm not sure how many different designs there are, but the GM I'm familiar with have a small electric generator attached to the input shaft of tranny, under the side cover. The outputs of these spinning magnets is a coil of wire that outputs to the computer and produces those codes during test or faults. Having to pull transmission to replace something so simple is just bad design. Add to that it often has internal wiring connections, adds to the potential for a failure. This should be redesigned so that it is as easy to change as one of those camshaft position sensors that sits on a valve cover.
Do a bit of research, possibly with reliable local shops, and learn if there is a better replacement part. This is one of those times where I would definitely shop for a different manufacturer. Be wary of Wells, I found durability issues with their replacement parts.
And since you have to go into it that far, consider other internal updating and renewing.

I hope they find the source, but it is also interesting that the fumes enter vehicle.
The CAF, cabin air filter, should eliminate odor, it is carbon impregnated. It is also positioned in the system such that it would filter the air in either outside air or recirculate position.
It seems you have a second defect.

Has anyone ever had a problem with it not shifting into overdrive? It starts out fine but when it gets up to traveling speed, it stays in that gear and doesn't shift into cruise/overdrive to reduce the whine on the transmission.n The tach reads 2 but the transmission is running hard.

Yes indeed, all the time. My car sounds like a tractor on the interstate. About 2 weeks ago, my car shut off again on me on the interstate, they changed something with the transmission. Look on GMC forums as well, you will find many other complaints posted there, concerning the same issues with car shutting off & transmission issues.

Good morning,
 
I'm sorry that you are having some difficulties with shifting. What year LaCrosse are you driving? Have you had it checked out already?
 
Best,
Sarah

butterfly1123,
 
How has everything been running since the incident on the interstate two weeks ago? You state that they changed something in the transmission - just wanted to check in!

At what speed do you have a tach reading of 2K?
What do you mean, "running hard?" What model is this?

Actually, from what I've seen, they dropp the tranny enough to get at the side cover.
Ford did for a few years have a bolted panel as part of the fender body area that could be removed so that side cover on the tranny could be removed without major work. I can't imagine why they stopped that.

I have that reading when I'm on the interstate mostly. Around 60-70 mph. I have a 2010 Buick Lacrosse, been having problems since 6 months after I purchased it & it was purchased in 2010 of the truck new.

When I say it rides hard. I mean it sounds very loud & seems as though it's straining. It's not a smooth ride like it should be.
