simple2me ive had the same problem with my sonic for 8 months now dealer kept trying to tell me it was normal until about a month ago when the whining became so bad it could be heard in all gears. it is so bad in 3,5,and 6 that the stereo can barely drown it out. Been waiting 3 weeks on the dealership to get one of their loaner cars back to give me. only difference in our issues is that recently I began hearing a horrible whirring sitting still in neutral with clutch petal out and noise stops when pedal is depressed. all issues started for me after they replaced a fried clutch at 14000 miles which gm made me pay for.

Final Update! Dealership picked up my car Saturday and gave me the loaner. I called Tuesday to get an update and didn't get a call until i was pulling up at the dealership (they knew I'd show up if someone didn't call me back). Met the service manager William and he said my car was ready that he had another mechanic go over the car and make sure everything was correct and that he personally drove my car and all is good. I take off and immediately noticed the steering wheel was still clocked at 10 o'clock. I didn't check everything else to see if they had done it until I got home and could look under the car. What do I find? the only thing they done was tighten the bolts on the spindles that hold the ball joints tight. the car was still missing the subframe bolts, vacuum assist motor bracket bolts. I couldn't get back to the dealership until Thursday mid day. I called them in the morning and left a message with the service rep and William the service manager and neither one of them returned my call so I just showed up right before lunch. The service manager saw me and to me, acted like he didn't notice me and walked right on by and went to each service rep kiosk and put a paint marker for them to mark scratches on cars that are dropped off for service. Then he exited the building for lunch. My rep finally showed up and I talk to him and he said it sounded like I need an alignment which wasn't covered under warranty. I then broke down the whole teardown process for replacing the transmission and asked him if any part of the teardown process involved removing the steering components, removing the subframe, etc... and then I asked him if it was their responsibility to put everything back together in working order. He answered yes so I told him he needed to get my car back in the shop right then and put it back together correctly, the same shape it was in when I dropped it off, minus the transmission problem. I told him I had no where to be and that I was going to sit there until my car was done, no questions asked. I showed them again what was missing and took a seat in the customer waiting area and conversed with every single person in there. Most of them over heard my conversation and asked me questions about my car so I gave them the whole story and like myself, they couldn't believe all of the problems I've encountered. Anyhow, the service manager, William returns as I'm outside talking with another employee and as he passes me, he spins around and says, "are you the guy with the transmission, why are you back here, your car was fixed and I personally drove that car" His tone and attitude lit the last little bit of fuse I left and I let him have it. Needless to say he went to see what was going on and came back a little later to apologize and say I was right and they were fixing it now. I told him I didn't want an apology, I just wanted my car fixed correctly and wasn't leaving until it was and once it was fixed I was never coming back to that place or recommending them to anyone for sales or service. I sat there until almost 5pm while they obviously searched for the missing bolts, etc... and installed and corrected my steering. They pulled my car up and i crawled as far under the car as I could and found everything to be where it should be and went inside to sign whatever paperwork I needed to and my service rep said there wasn't anything to sign that they didn't write it up, I was okay to leave. I bet they didn't write it up, just proves that they didn't do it right the first or second time. Anyhow, everything is back together and the transmission shifts so much better than the old one did so kind of makes me think the other one had a problem from the beginning. Didn't they change the transmission gear ratio for 6th gear. I don't know if it's the same or not but I swear my car actually picks up speed in 6th gear now when i accelerate. Maybe I'm just imagining it since I haven't driven the car in so long, idk.

Glad you finally got it back with all the bolts in, your fuse is much longer than mine. I would have insisted they write it up, too, in case you have problems down the road related to their screw up. I'd go on every review site and pound that service department to the ground so others can be warned. They would have probably had to call the cops on me.
just some info on my car. i too had the trans wine in 2,5,6. it took over 6 months and a lot of trips to the dealer, then switching dealers and the gm rep on here Erica Tiffany was a huge help on getting it taken care of. gm did put a new trans in my car and i can tell you that it is so much better now. you don't realize how bad it is until it is changed. for some reason my clutch petal works so much easier. the shifter no longer moves 2-3 inches with the gas pedal. the shifter moves so easy and effortless. i recommend that if you are having problems just keep after them. it is well worth it.. and again a huge thank you to Erica Tiffany for her help with this problem..:banana:

Did anyone ever get the tsb numbers for this?

There isn't a TSB for the 2,5,6 whine. The only TSBs or PIs out there are for the 2nd gear grind and shifter adjustment.

Mine only made noise in 5th and 6th. 6th gear being worse. I never had a problem shifting the car, just started making noise one day. Car is running fine now. I have to get it in the air this weekend to adjust the frame. I hit a water puddle on the hwy and now my steering wheel is clocked to the right now. I don't think the dealership tightened the frame correctly and it shifted when I hit the water. The car drives straight, just the steering wheel is jacked up.

at 62 thousand looks like i can add my name to the list of whiners. dealer has car now.
Someone should get a survey together detailing who is experiencing these problems. I'm interested in the mileage of the car when the whining was first heard as well as the model year.
Am hoping Chevy is doing something to actually fix the problem and not just re installing m32's which may eventually fail again... Can any of the Chevy Customer Service Rep's comment on this?

Just read through an astra thread littered with m32 bearing failures. Sounds like a number of individuals have had multiple transmissions fail on them... While I don't hear any whining now I have to admit I'm a little but worried.

Over on the Vauxhall forum a number of people had gear whine and bearing failures (usually noise in 5th). GMs solution was the same as over here, throw a trans at it. However their resident trans guru was rebuilding out of warranty trans for forum members and determined one of the bearings was being starved for oil.
After awhile, he got an M32 trans that had a redesigned case that was updated to promote better oil flow to the troubled bearing. Not sure when GM did the redesign but I suspect it was fairly recently, GM never mentioned the redesign, same with the beefier 2014 clutches.
What that says to me is GM is aware of atleast some of the issues and is slowly and quietly working at fixing them............ If only there was some way for them to study past designs to see what has and hasn't work before, or if there was some way to anticipate what makes good materials and designs for manual transmissions.............. I suppose not since manual transmissions and gear boxes are new technology without much recorded information, kinda like ray guns.
At anyrate one backyard fix has been found to fix or atleast mitigate most of these issues, dumping the factory oil and replacing with a quality syncromesh fluid. Redline MT was the old fluid of choice, but from what I've been reading and from experience Amsoil 5w-30 syncromesh is among the best fluid choice for this trans. Overfilling by .5qts (2.5qts total) has also been recommended to help fight heat.
Good info, thanks sx sonic!
I have a MY 2013 built in Nov of 2012 -I'm hoping it has the revised design... Guess I'll be picking up some gear oil tomorrow, I'm at 13,000 miles and I'm hoping damage hasn't already been done....
Can anyone confirm weight and amount of oil for this transmission? 75w-90 seems to be the weight I keep stumbling across but I've seen a number of different numbers for total oil capacity. I've seen everything from 2-3 quarts depending on the forum.
Thanks everyone.
