Corvette c7 2014 A6 problem shift 5th to 6th gear
Hi there
I drive a C7 A6, 6L80e differential changed to 3.42.
Also changed the table for differential and tire manager
The problem now is that at full load 5500 rpm and a speed of 245 km / h it does not shift into 6th gear.
If I drive with 6 gear it switches at 5500 rpm. back on 5th gear.
Can someone help me why?

You Normal shift Km/h in 6 upshift doesn't match the Full Throttle Shift Speed 6th
Your normal shift speed is 300 at 100% so it's waiting until 300 KM/h to shift.
and your Full throttle 5-6 is 272 km/h so it would shift until then either.
Those two need to match.

It does not switch in TUDU mode at 5500-5800 Rpm, is everything influenced by the other tables?
Can you change my tuning so that it fits my car?

Im looking at the tables yesterday. I have compared the zl1 table with ss. The shift pattern B is ( ss performance) (zl1 trailer).
after changing this to trailer on my ss the shifts seems to be in sport mode when im in D .
The shift sheduling is now pattern a=b and b=a wich means the shift pressure pattern x and y is even changed.
So actually D and S (M) are interchanged and I will change all the other tables (pressure, schedule, timing) , when the high speed shift works.
I didnt test it, but the shift speed under the tables from the zl1 looks like they do a high speed shift.
Just compare the files from repository and you know what I mean....

The Bluecat tool is excellent for setting up your shift scheduling.

Has anyone play around with speedo hardware?
Because it seems to be a problem by VSS signal to/from TCM .
Speed output type can be : vehicle serial, vehicle repeat tos or wheel speed.
