a4 shift firmness?

[ls698ta]

how can I tune my a4 to shift better? I have a stock stall and a ls6 with long tube headers,3.42 gears and a 275 tire. here is my tune

try lowering your desired shift times for starters.

to what?

Try this, all I did was simply lower your shift times.

cool thanks

[ls698ta]

ttt!!!! is there a reason why the 3 to 4 shift should be 0?
thanks

All 3-4 ones are 0, just means its not trying to slow the shift down. I know mine were 0 from GM, and I run with 0ed shift times but Im not making as much power as you are. Looks like you're already running no TM, thats another big area where you see lots of improvement especially with ETC vehicles.

IIRC - zeroing out the desired shift times merely disables the learning ability within the tune. If there are numbers popluated, the PCM will make adjustments to try and achieve them.

Assuming you're not running a shift kit, I'd set the desired shift times to somewhere in the .17~.20 range where you want it to perform. Then, bump up the line pressure about 5%~10% on the top end and cut torque management on the upshifts in 1/2. If you bump up the line pressure too much, the trans probably won't last - especially if you kill torque management completely.

Let me correct myself, I would suggest running the shift times sspdmon recommended and upping the line pressures on LSx motors. But I have an 4.2L I6 pushing 270/275 flywheel (says GM), about 100hp short of you guys so I should theoretically be able to run with 0ed everything, shift times, TM, etc. However unless you have a built trans for an LSx motor I would NOT recommend it.

ok well I have mine set at is that fine? or can I go lower?

Try it first - the trick to tuning the trans is to make moderately small changes, observe how it reacts, and adjust again if necessary.

Exactly, I started off making really small changes (like taking 20% TM out and lowering shift times 20%) and went from there. Eventually I figured out I can run 0 both, but I would strongly recommend against it for your engine as your trans will probably end up in pieces if you do after a few thousand miles.

Or if your motor/trans survive, your axle might not... what lives depends on your mods... and your tires will take a beating.

You can tell when you're in this range by how hard each upshift is (and how easily traction is lost).
