A4 Shift Points
I've noticed if I get on the gas lightly the car shifts around 2000 rpm, if I get on it a little more it shifts around 3500 rpm. My question is can the shift points be programmed to a higher rpm and how is it done. Right now I drive around the city in 3rd so it will stay out of 4th.

Re: A4 Shift Points (GrayGlenn)
There are several tables in the PCM that determine when your A4 shifts in regard to your current MPH and thottle position angle. At WOT shifting at RPM is also a factor.
These settings can be tweaked if you have the right software.

Re: A4 Shift Points (GrayGlenn)
most of the handheld programers will allow shift point changes only during WOT.
I don't know for certain, but maybe LS1Edit will allow the changes you describe.

Re: A4 Shift Points (IMQUIK)
:confused: Those aren't the shift points I suggested.. here is what I sent:
1-2 38
2-3 73
3-4 119
2-1 33
3-2 69
4-3 115
RPM
1-2 6000
2-3 5900
3-4 5900
The PCM must meet both conditions of RPM and MPH before the WOT shift. Again this is only for WOT. The part throttle tuning has a little more complex shift table.

Example of stock normal shift points (based on TPS%) that you can edit in LS1-Edit:
1-2:11 11 12 13 15 19 22 25 28 31 33 35 36 37 38 38 38

Re: A4 Shift Points (Tlkschep)
To conservative for me, i like the 6200 rpm wot. But the Rev needs bumped up to, say 6500. I have a friend shifting at 6500 and it pulls real nice their.

Re: A4 Shift Points (Tlkschep)
Does changing the shift points change the way the shift feels? My car shift fine at low speeds however when I step on it from zero, it feels as if it's gliding into second. I have a Ford Crown Vic police interceptor that I drive at work and it does the same thing. Problem or "that's the way it is"?

Re: A4 Shift Points (Greg5)
Changing the shift points in no way affefects the shift feel! :D
Shift feel is controled by main line pressure and accoumlator rate or pressure and clutch clearence.
Just because it shifts hard dosen't mean it will last long!!!!! :D

Re: A4 Shift Points (Greg5)
I tune Fords and GM's and they both have shift pressure tables for every gear and range from part throttle to WOT. They are based on the % TPS and adjusting these will make the shifts firmer or less firm so it's wise to be careful when altering shift presures. Both manufacturers make soft shifts in the stock tables to make your ride more pleasant. There's lots of room for firmer shifts without breaking anything. :cool:
Shift parameters like 1-2, 2-3, etc are on other tables and are based on % TPS and mph. Just like the above posts. Good discussion! :cheers:

Re: A4 Shift Points (Mr Cowl Hood)
I had the following done to my A4:
Removed TMS, quickened shift times, increased line pressure from 83psi to 86psi
I believe that the above items are SAFE to do and actually can increase the life of the transmission.

Re: A4 Shift Points (runamuk)
Why would you have 1-2nd as your highest shift point? It's the gear that needs the most cushion between rev limiter and shift. I have
5950 1st-2nd
5990 2nd-3rd
With the limiter@6300
I tried as high as 6050 but the car would bounce the limiter every time so I had to back them down. It seems that the car needs atleast 300 RPM's to shift. This is with +10% shift preasure -10% shift time on my predator.

Re: A4 Shift Points (Demented)
I am interested in having my shift points adjusted, increasing the line pressure and removing the Torque Management System (TMS).
Where could I get this done around the DFW area and what would it cost (approximately) :) Thanks.

Re: A4 Shift Points (bgood)
I'm confused... wouldn't these shift points apply to 3.42's w/ SY3500 as well?
