Vehicle has 36,000km and still jerks into gear when engine is cold. Both in drive and reverse. Is anyone else having this problem?

Also, heat coming out of vents when all dials are turned off. Nothing like having the top off and windows down and heat coming out of vents. What the hell?

I have a 2015 Z51 with 40k+ miles and it still jerks into gear also when the engine is cold. I've mentioned it several times when getting the Z51 serviced but the service tech's never do anything about it.

Have you let the car drop to base idle before putting it into gear? On cold start with advanced idle it will certainly jerk when put in gear.

The C7 has a tremendous amount of heat buildup in the engine compartment and it will heat the air in the ventilation system. You may find you are better off leaving the temperature turned down (but not to min or it turns on the AC regardless of other control settings) and run the blower at moderate speed to force more air through the vents. Or just run the AC.

I always allow the Z51 to warm up and drop to the base idle around 650 rpm's. When starting in drive, I now place it in manual and shift from 1->2->1->D before driving. This helps but is a pain to do every time.

I always let it warm up but am not understanding why the hell this is happening on a vehicle I've spent this much money on

I've actually have run the ac on the floor setting even with top off and windows down. Childhood dream car isn't such a dream anymore

After 22,300 miles you're "whining" about the hvac mistreating you? Get a Prius.

Hey ******* with the Prius comment, you obviously have too much money. I spent a lot of money on a brand new vehicle to work properly. Last time I ever buy domestic. Back to German engineering where the quality is

If I recall, the Jerking on cold start is a known issue and is a bad seal on the torque converter that allows tranny fluid to leak out of the tranny and back into the tranny when the car sits. I understood that if you start it up, and wait 30 seconds before shifting into reverse or drive it does not jerk.

Be sure to input your issue in this thread.

My 2006 A6 did the same thing even after 8 years and over 200 1/4 mile runs. Let it warm up and your problem's solved.

Is that correct? I've been told three times by my dealer that this behavior is normal.

In any event, the tracking at that link doesn't address this issue or any circumstance where the dealer refuse to perform warranty work on this issue.

madrob2020

Sheesh! Point being that if you bought it "brand new" & now have 22,300 miles on it why complain now instead of "then". Next time don't get your panties in a wad when someone digs on you. If you read this forum folks "make light" of posts like yours alot. Possibly a Troll since this is your whole 4th post.

For the early production cars there is a repair to prevent the leak down and slow engagement but it is quite invasive because the transmission has to be pulled and opened up. Here is the TSB: http://www-odi.nhtsa.dot.gov/acms/cs...74343-0699.pdf

I have a March 2016 production Z06 and there is no delay or jerkiness going into gear; it was built after the updated parts.

Mine didn't improve until they replaced the transmission. Its still not perfect, but significantly better.

Sure it does - just vote saying it was not resolved (fixed).

I took it to my desler 2015 3lt they told they did a software upgrade but it didnt solve anything. I have noticed thst if amI let it idle a couple of minutes its smoother

Mr. Smith

Mine does this too. It's had the problem since I bought it brand new, now it has 12,700 miles and the problem is the same. The dealer re flashed the computer, but it didn't help. It's very intermittent and only does it maybe 60% of the time and mainly when it's cold or the car was sitting for a few days before start up. I've also had my torque converter replaced at around 9,000 miles. It's really annoying and it clunks pretty hard sometimes.... that can't be good for the driveline over time....

My first Vette and my intuition told me to let it settle down to about 500 RPMs upon starting it up. I also noticed the AC automatically comes on when I turn the temp down to the lowest setting (61 degrees to keep cool w/ the transparent top during the summer mos.). Another source of much heat is from the engine compartment -- a LOT of power under my GS
hood!!

And....there's no such thing as too much money. That is an idiotic comment.


Enjoy your Volkswagen.

I have a 2015 Z51 2LT Auto and it needed a new water pump at 20,000km, new tranny at 43,000km (because of the jerking into gear) and 3,000km later the jerking into gear returned. Dealership has since replaced what was formerly a 2 piece harness (not sure what that is) to a 1 piece harness and time will tell again if the jerking returns. Yes to hot air with nothing turned on.
The jerking is very common with this car and with a standard as well. It also happens in their GMC and Chevy trucks. DO NOT let the dealer say they haven't heard of it cause they have. You are not alone with this issue. Go on Youtube and you will see many vehicles having this issue
Stay on the dealer to fix it. They will do what is called a program re-learn on the tranny which will fix it for a short period of time but it will return. You will have to jump through all the hoops to get a new tranny. Maybe GM will fix the problem before sending out the same tranny with the same issue. Once again GM quality control not there. Back to German engineering I guess
