A6 low gear hesitation update - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

abaucom21 · 08-25-2011, 02:39 PM

There were other threads regarding a low gear A6 hesitation a month or more but can not find those threads that I responded to.
Posted my 2011 Camaro was dignosed with this issue (specifics on other threads I can not find now on this site).
Apparently I was first that GM recorded with this A6 low gear hesitation.
Result: My Camro has been in the shop for a week. A TCM (transmision control monitor) was ordered a week ago, still waiting for part to be delivered to my GM dealer in Canada.
At my GM dealer I have two managers working on my Camaro. They think the low gear hesition is the TCM, will replace TCM and reprogram.
Wait and see.
Sorry that I could not find past threads on Camaro5 so that is why I started a new thread on this A6 transmission hesitation issue.
Perhaps by next week the TCM part will be delivered (why does it take a week or more for GM to deliever this part?).
Once part is recieved and installed my dealer will run a computer check, also test drive.
Will do my best to keep you all informed.

Happy, just 5 minutes ago dealership called me.
New TCM received and installled, and programed. My A6 2011 Camaro has 3,045 miles in 12 months.
Two service managers checked programming and test drove my A6, 2011 2LT Camaro after new TCM (transmission conrol monitor) was insalled.
Issue was, confirmed with a test drive: "Test drove with customer and confirmed shift flare between 1-2 gears at approx 25% - 40% throttle opening." The flare was about 400 rpm when it should have been 200 rpm between gear shifts during fast acceration.
Bottom line a few others on Camaro5 with the A6 transmissions noticed a slight low gear hesitation. It appears there might be an issue with the TCM (transmision control monitor).
My TCM was replaced, programmed and now my A6 shifts fast without any hesitastion in low gear changes.
Only found on Camaro5. If others had not posted first, I would not be the first to resolve the issue. So now you know if you have an A6, noticed a low gear hesitation only during fast excelleration, fix could be replacing the TCM (transmision control monitor) under warrenty.
Hope my experience helps others.
