I could really use some help on this one. I have a 2011 Cruze with a 1.8 liter. I recently had my Cruze shipped to Hawaii and figured at 140k miles I'd drive it another year or two and trade it in or sell it. I'm on a pretty limited budget because moving to Hawaii is super expensive. My wife was driving my car up a mountain and all of a sudden lost power. The check engine light came on and the abs light came on. She had it towed to the only certified Chevy place on the island which is actually a Toyota dealership. We had it there two days prior for an oil change and it took 3 hours despite having an appointment and the service advisor didn't even know about dexos oil. So my wife sat there for 5 hrs and they told her we needed a new transmission for $7000. I talked to the assistant service manager and asked what the tech did to diagnose the problem. He said they hooked it up to a diagnostic computer and pulled code p0776. He said there may be a bad 3 5 R waved plate but wasn't sure and suggested replacing the trans. I asked him if they had it up on a hoist to do further diagnostics. He said no. So I knew they didn't even check the fluid. I went to the dealership and begrudgingly paid them $87 for something I could of done myself with a $15 scan tool. I drove it home 60 miles up and down hills with no problems. A day or two later I started getting the same issue. In about 4th gear around 40 mph I lose power, it revs way up check engine light comes on followed by service stabilitrac and traction control. I got a scan tool and I'm getting these codes. p0700, p0796 and p0300. It seems like it might just be a solenoid issue. Would that be an expensive fix? I had the trans flushed about 30k ago. Would some seafoam or lucas trans fix and a flush get it to trade in quality? If I had to bite the bullet and have somebody replace the waved plate would it be worth it on a car that only blue books at 5k? Some insight into the issue would be appreciated.
