That price included diagnosis and installation. AYK, finding electrical problems can be tedious and time-consuming. It was in several times for the battery run-down and the dealer couldn't duplicate the problem and didn't charge me for the unproductive visits. While I've learned a lot about cars over the years, I haven't done much of my own work, other than plugs, LOFs, belts and hoses. I wouldn't take on an electrical problem other than replacing bulbs or once splicing some wires after a deer strike.
When it comes to trouble shooting, I figure the dealer sees a lot of these vehicles and my dealer had a guy that specialized in electrical problems. The persistent run-down also burned out the alternator and wrecked two batteries before they found the problem. The alternator and battery were original and probably ready to die anyway; they replaced the second battery for free because it was only a couple weeks old and was tortured to death by the repeated run-downs (I carried a battery-pack for a month cuz I never knew when it would be dead).
The Compasses in 08 had somewhat problematic transmissions to start with.
True. My '08 Patriot had the same CVT as the Compass and it was replaced twice, first at 110,000 miles and the second at 270,000 miles. Fortunately, in '08 they were giving free lifetime warranties so FCA replaced both my trannies free for nothin'.
The transmission is not a very good area for beginners if you truly do have bad pressure sensors and solenoids, as the current codes indicate.
On the other hand, the CVT is so simple that doesn't have much to go wrong with it, and when it does fail there's nothing that's practically repairable. If the transmission isn't slipping or making weird noises, Isaiah might not have a terminal problem. With that many miles I'd first guess it is an electrical problem throwing all those codes. However, you're right: an amateur like me isn't likely to make an accurate diagnosis based on an internet post. I'm just suggesting a place for him look.
