Hi, I'm new to the G6 site, am trading my 04 Malibu LS for a 09 G6 sedan today, I know, I'm a glutton for punishment. Got a good deal from a bankrupt company for a discontinued car.
The reason I'm posting is I have read a few of the transmission hard shift problems. I am aware that certain codes will cause the transmission to go full pressure and will hard shift. Has really nothing to do with a the trans, the code problem just needs to be fixed.
 I'll be hanging around.

Update, The service guy called this morning and they believe the problem is the connector on one of the actuators. The new guy on here is correct about the codes causing high pressure to the tranny. Apparently one of the connectors is broken and therefore the actuator is not working. The acuators are on top under the plastic cover. They are side by side, the one toward the front of the car is the bad connector. Something you may want to check as well. It could be cam pos sensor going bad, the actuators, connectors, wiring. But the good thing is that the tranny is fine. I am also having them checking the steering for the GM's infamous clunking noise. They are going to see if they can grease it otherwise a loop kit cost around $100. Mind you, this is not a safety issue, just a nuisance:) The connector is still going to cost me $50.

Hi New guy, I don't think you will be dissappointed, I do like the car, rides and handles well. I had a Grand Prix GTP, that I traded in for this car, The G6 actually has more room in side from front to back. The G6, believe it or not, handles better that the GTP. We usually get 26-27 mpg all the time, mixed driving. Haven't done any roadtrips yet. I think all manufactures have some things go wrong, this just took a liittle time to figure out. The connector on the actuator is hopefully the problem with my G6. Talk to ya.

I bought the base model with a the Sun and Sound package also Preferred group, pretty well loaded. I thought it was cool to check tire pressure using the DIC. Only have 70 miles on it so far.

Thankfully, the car is actually running better now! When the car was in the shop being inspected, I had the oil changed, then I picked it up. I am finding the engine to run better now. I did push the oil change past due this time. It had been last year early winter, late fall?. So, it needed it badly. The performance is much better now too, the true test is when I am driving up and down hills. It doesn't want to change gears as much to keep it going through the hills. The rough shifting is pretty much gone.
 
Hopefully, this was the issue, because it does feel better. Who knew a simple oil change would make a difference.
 
I am thankful for my warranty. I also need to take a step back and realize its a lease... not forever, its just a car. Either way, I know I won't keep it the whole lease... next year this time I will have a better position at trading. 1yr in, and trading is too soon. I have to be thankful for what I have.
 
I really love the car.. it may not be what I want, but it certainly pampers you with all its features. Some of which cannot be had on others.

OK, now we're getting somewhere - I wondered about that too after reading the TSB's on chaffed wiring to those sensors. When inspecting mine I could see that the one at the rear of the engine (toward to firewall not the front of the car) has been taking alot of oil run off - possibly from a few drops missing the filler opening at the top of the motor during each oil change process. It certainly looked much more grimy then the other connector.
 
Is that the one they are replacing ? The Code that is coming up (P0010) is the actuator for "Bank 1".
 
If you could let me know if that is the one they replaced (connector) and perhaps what the part # is on your invoice - I am going to give that a shot.
 
Loop kit ? Never heard of that - the front end noise is usually a weak lower control arm bushing or the input / output shaft on that side of the wheel assembly. There are TSB's that point to it, greasing it only lasts for so long.
 
Cheers...

I genuinely hope you have great luck with your new car. I absolutely loved my first G6; it was an 06 Sedan GTP automatic, fun to drive reliable roomy for a smaller car. It had everything I wanted, I loved it; mad as heck that I let a "friend" talk me into trading it in on the one I have now (07 Coupe GT, manual); lower payments, cooler look, little better gas mileage... it all sounded good .... if I would have just kept the 06 it would be paid off this month and I would still love it; I am sure of that.
 
this one... at only 13K miles I the nightmare of the last two years started. Not all G6's are bad, supposingly they have decided that the 07 with 3.9L (GT) manual transmission has a programming issue, it's never been right.... imagine that... just what I have been saying for 1.5 years!
 
Wishing all the best, enjoy your new car!

Pontiac G6 Manual Transmission; Programming Problem by stephsteffens

After a year and a half of complaining of problems with my 07 Pontiac G6 GT, Manual Transmission, everything from electrical shorts, to burnt clutch, you name it, it's never never run right. It has been in the shop for well over a month now; replaced everything they can guess to replace brought in an engineer; supposingly they have determined that the programming in the car is flawed. That it has never been right ... hmmmmmm never been right..... just what I have been saying since it was new and no one would listen to me. Now they are telling me to come pick it up because there is nothing they can do until they write a new program for it; but "its good news because we finally know what's wrong with it". BS They say this car is extremely rare so finding others with the same problem is unlikely.... hello if it is in the Computer Program that runs the car EVERY ONE will have the same problem. DUH.... If you own one of these cars you have a problem, and it is not in your head.

Dave, I replaced both sensors but it is actually the connector to the actuator on the top of the engine. If you take the plastic cover off, you will see, what looks like two sensors, to the left side. They only about an inch apart, The front actuator connector, is what they are telling me, is bad. I talked to him again yesterday to confirm. I didn't see anything wrong with it but will give it a try. The connector is going to cost $50 and that is ridiculous. He said it isn't making good contact and if you move it around then the actuator starts working.. I will be splicing on the new connector hopefully Friday.
 
 Yes the code (P0010) is for bank 1. I will let you know about the connector part # for the actuator, if that is one you want. I hope the dealer and I are talking the same language. That is why I called him again yesterday. We drove the car for a few hours after he reset the computer and it drove great untill the light came back on and started shifting hard, once more..
 
  I meant lube kit for the steering shaft. Don't know what I was thinking when I wrote that. Didn't need the kit, they tore it apart and lube the shaft and it is like new again..

Very interesting. Which connector to the Cam Position sensor is the bad one that they discovered ? The one at the back of the engine (closest to the firewall) or the one to the front of the engine. I think Bank 1 is the back. I can see that the sensor there takes alot of dirt off the back of the engine, the connector itself has some oil residue / runoff on it from the top of the valve cover (few drops maybe at oil change times) I bet this is causing an abnormal resistance at the connector and thus the ECM thinks the Cam Sensor is acting up. You're saying yours are about an inch apart ? Are we looking at the same thing ? My Cam position sensors (2.4L engine) are one at the front and one at the back. If you mean left & right, as in passenger side and drivers side - then I am confused. Mine are both on the drivers side of the motor, one at the front and one at back.
 
I am going to pull mine apart this week (connector) and clean it thoroughly with electrical contact cleaner then re-install. I don't see how they can become loose or bad in any way - they are simple connectors. $50 is crazy I agree !
 
I did the same steering shaft repair under warranty as well, worked for awhile until the grease wore out. They eventually diagnosed a bad lower control arm and replaced that.
 
Let me know what you find out on the part # from your invoice. Appreciate it... Cheers
