Thanks for taking the time to let the readership know how you finally resolved your problem.
now GM has told me it is the shift adapter and it will resolve itself after 5,000-7,000 Kms. i find that hard to believe and am wondering if anyone else experienced this issue and what was done? given i just purchased the vehicle i'm hoping earlier buyers of the car have some info.
New bulletin.
#09-07-30-010: Harsh Transmission Downshift When Stopping After Transaxle Has Upshifted to 4th or 5th Gear (Reprogram Powertrain Control Module (PCM)) - (May 13, 2009)
Subject: Harsh Transmission Downshift When Stopping After Transaxle Has Upshifted to 4th or 5th Gear (Reprogram Powertrain Control Module (PCM))
Models: 2009 Pontiac Vibe
Equipped With 5-Speed Automatic Transmission -- RPO MVD
Condition
Some customers may comment that they experienced a harsh downshift feeling when coming to a stop after the transmission has been in 4th or 5th gear.
Cause
This condition may be caused by the PCM calibration for the 2-1 downshift not being optimized.
Correction
Important: Before proceeding with the reprogramming procedure in this bulletin, the Vibe Programming Application MUST be downloaded and installed on the PC. Refer to Corporate Bulletin Number 09-06-04-006.
A revised calibration has been developed to address this condition.

i'm concerned if the problem does not correct itself as suggested in some forums that i'm stuck with this problem with no recourse.
I just read on genvibe that you are indeed correct; people who have had the computer reflashed have noticed only a modest improvement, and MOST important, that this problem is also prevalent in the Corollas and Matrix. Toyota has a problem here, so I hope their engineers are trying to find out what the solution is. You can research this on many Toyota chat sites. We're all in this together.
I called the toll free number to GM Contact Center to register this complaint, and they told me they will stay on top of it and maybe have to call in a Toyota Engineer to service our car.
I was polite to tell them that if after this problem is reported and an accident happens I will gladly sue.
Anyone have any luck getting this problem fixed? I can't seem to find any information on the surging??!? Seems to be getting worse with time. :confuse:
i received a call from GM today regarding my complaint and they are convinced the issue will resolve itself after 5000-7000 kms. in my case if it still pursists after that i will get some type of resolve....whatever that means.
anyway i'm taking this conversation to GenVibe as there may be more hits on the issue.
maxx thanks eh.
What I most want to know from all of you is: does anyone's Corolla Vibe (1.8 liter, 4 speed tranny) downshift from 4th to 3rd when going down a hill when you just tap the brake? It acts like a brake assist feature, which to my knowledge, does not exist. With all due respect to genvibe, they are pretty much asleep at the switch over there. We need more discussion on this issue. At genvibe, they seem more interested in saying hello to new members vice discussing serious issues.
Any thoughts from you 1.8 liter 09 or 2010 Vibe owners would be greatly appreciated. I don't hold out any hope that my tranny is still "learning my driving habits" and the downshift issue will go away over time.
In the end, my greatest tranny frustration occurs when I have the air conditioning on, and I need the car to downshift to pass or accelerate. I often get a serious delay before the car will downshift from 3rd to 2nd to give me more power. At other times, I can "slam" the transmission when pushing the car to downshift to 2nd. Anybody else have a similar experience?
Usually keep an eye on the temp gauge and always below the half point.
Then about a month ago in the hot summer days, the A/C would be intermittent.
I thought maybe an A/C problem as the car is almost 7 yrs old.
Then I noticed the temp gauge was hot. Apparently, the A/C would shut off if the engine temp gets too hot - like almost 7/8 of the gauge.
Added about 1.5 quarts of coolant (prestone green) as this is an older Vibe. Also filled the overflow/recovery bucket.
That fixed it for now and the A/C is good as the temp gauge is back below the half.
I noticed some powder stuff on the top of the fan/radiator near a rubber mount - Drive side. The coolant cap is on the pass side.
Anyone have a slow leak and how often?
Anyone needed a new radiator yet, and when?
Tx in advance.
I have an appointment with the GM dealership to have it checked out, but not until next week. Has anyone had a similar issue?
A few things to note: I normally park on an incline with the parking break on. I don't do much city driving, mostly highway, and most days I don't drive at all. Less than a month ago I had an oil change and safety inspection (they are legally required where I live) and according to the mechanic, everything was fine, and the fluids were good.
Any thoughts?
this was an intentional design.
The car now runs great, and is shifting gears smoothly as before.
Good luck.
Sign me NUTS in Alabama.
Also, it seems as if the older models were under 8/80,000 and if I'm right, now the newer models are 3/30,000 warranty. Does this indicate GM is aware of the problem? My older 2005 car developed this problem at 78,000, almost 2,000 shy of having to pay for the repair. Whew!
I just want some idea of what needs to be done so I will know if the dealers mechanic took care of the whole problem and doesn't leave me with a repair job next month. Any ideas?
A check engine light may be experienced with dtcs p0171, p0441, p0455 and/or p2420 - inspect production part number on pcm.
I have one week left on my warranty too! Not sure what will be involved. So frustrating!
We also have a 1996 Toyota Avalon which has had a lot of work done on its engine. The bottom of the car has rusting problems and has had its fuel line and exhaust system replaced. The car still runs pretty good though and Avalons can last a very long time. We are probably going to trade/sell both cars and buy a different used car, hopefully on with fewer miles on it.
I am also wondering if this malfunction is the same problem described in TSB 050604074. Has anyone had their PCM [power-train control module] replaced?

I'll be glad to give you step-by-step instructions.
I can almost promise this will eliminate all oil burning/loss.
