A10 - 5th Gear

[hawkbox]

Do any of you with an A10 notice it shifting super rough in and out of 5th or notice it have a hard time with 5th being right about where it needs to shift for traffic?

Curious - I am wondering if its just learned KAM values that a good battery off reset will help, or......

yes!..same on my car.
also....once on 5th....the progression is not "linear"....
press and keep accelerating....but once i get to 5th..the rpms actually lower!for the half a second almost as if it hesitates for sec..and then keeps rising......it only does this on 5th.....is driving me crazy.

48xx miles of driving the A10 and can agree to that 100%. This 5th gear affect does not seem so prominent when shifter is in S.

Are you guys shifting manually since you know what gear the transmission is in? Or do you have the LCD display and will it show the gear in automatic?

In my GT no automatic up or down shifts using D or S in N, S+, or Track drive modes are noticeably rough in normal driving but I don't know which gear is being used.

Here is a gear chart/graph. Note that 4th - 5th has the lowest rpm drop except for 9th - 10th

Dick,

What software or program did you use to extract that chart? Pretty cool tech.

I can also agree with Dick’s response - when the A10 is in “D” or even “S” with no manual intervention of the driver using the shifter paddles - the display (at least with analog cluster) does not and will not display the actual gear # as the trans is auto shifting up or down.

Only when the Driver starts use of the paddle will a gear # be displayed (again analog cluster). In “D” using paddles, the gear # only displays when shifting, if the Driver does not shift, the auto up or downshift occurs and the gear # is no longer displayed. When in “S” and manually shifting, this is the only setting or time when the actual gear # will be retained in the display (analog cluster) UNTIL the Driver chooses the next gear.

So I too am wondering how you guys know the issue is with 5th?

I’m also not experiencing any issues with my A-10 in any gear.

I have the LCD screen but i havent noticed any issues with 5th gear, or these PP or non PP?

Norm Petersen created a spreadsheet which includes gearing charts which he shared with me early this year. I recommend that you PM Norm.

I wouldn't say rough but I've notice that the computer seems to be confused on whether to lock the converter or not. Its more of a quick engagement or at times a slight hesitation. It gives you a herky/jerky feel at times. I noticed it both pre-tune and post-tune. For me its most noticeable when I part throttle it but not enough throttle to go into a passing gear. Hope that makes sense.

You described it perfectly. It does seem as if its not sure to lock the converter or not.

LCD Display..non PP car...Normal Drive mode.

Yeah, I really don't understand why us base guys don't get to see what gear we're in unless shifting manually in sport mode. It merely needs to display the number. I would really like to be able to always see what gear its in for my own knowledge of the shift strategy, etc. I wonder if a tuner could add that in a tune or something. Its obviously just a software change since it is capable of showing the gear. Here comes an email to Lund....

So glad someone else is seeing this - I was worried for a min...

This is very much what its like but it slams the damn thing into 5th when it hesitates....crazy - its mostly after partial throttle when trying to pass and not needing a John Force blow by of the car I am going around.

Oye...welp guess I will take it to the dealer and start a file on it JIC.

Ohh and its in Sport mode - not sport plus.

Thanks for the assessment guys! :cheers:

John Force blow by = perfect description

Sorry to resurrect this old thread, but I notice the same exact thing with my A10. I have the digital dash showing the gear and it is very rough (jerky as someone else mentioned here) on both up and downshifts to/from 5th. In S+ mode (shifter in D), while playing with the 0-60 acceleration timer, the car jerked so much going to 5th that my foot actually lifted off the pedal and confused it even more. In general, the transmission seems like it gives me the quick shifts as advertised some of the time (mostly at low power), and others it's just hesitant and sloppy (higher power).

I'm going to try again with the shifter in S and see what it does.

Did you ever take it to the Dealer for diagnosis - if so, what was the result?
