how to m ake an A4 shift quicker and crisper i was wondering what do i need to do to my A4 to make it shift quicker and crisper? i hate that spongey shifting. i dont like it when you u slam the pedal it goes up to like 5500rpm and when its ***** it goes back down to liike 3500 it there anyway to fix that so it only drops down alittle bit?
shift kit & converter...shift kit will make your shifts crisper at least...the converter with a decent shift extension will keep the motor in its powerband instead of dropping the rpms down so much.

If you get a high stall and do alot of low rpm street driving, it will. The converter sliups alot and heats up. HEAT-VERY BAD FOR TRANNY. Also, if you're planning on using a high stall, save and get a good tranny too. Stock 4L60E's don't last ;ong and when the tranny goes, 99.9% it will take your $450 converter with it. METAL-BAD FOR TRANNY! Call Jim Pace PP and ask about a Hughes. Got mine for $1600 and good for 700+hp with a 2800 stall for my wifes IMP SS

I have the bolt-in and it was very easy to install. The hardest part was cutting the plastic for the covers.

If you are going to stuff around with shifts in your V8 powered LS1 I would recommend getting it rebuilt or toughened up. You can go to 0.3-0.4 seconds for shifts in a stock 4L60E but thats it. It will cark it down the track if you go any quicker without some mods for reliability.
Yes, a converter will work. However, consider a diff ratio change if you havent already. The stock converter is really tight and so will not slip much. Its your diff gears that will determine your shift extension with a stock conveter.
Everything else said here hold true. Itys a qwuestion of what you want out of your car.
Do your care about reliability?
Do you just want a track warrior?

At WOT with a stock (tight) converter it will tend to follow your gear ratios so a shift from 6000 to 3500 with 3.46 will now become 6000 to 3500x8% with 3.73 gears, or 3780.
Race converters are designed to slip so that the converter will take some load off the gears to bring it up to speed. You're riding the converter and diff and more converter slip will increase your SE but be more inefficient.

That's because they don't....at least not enough to matter. With a really tight converter it's much like a manual tranny in that the tranny ratios will determine your shift extension. Changing the rearend ratio is NOT going to help the SE of your converter very much at all. The only reason that it'll help at all is because the car is easier to accelerate with numerically higher rearend gearing (the ground speed is catching up with the RPMs quicker during the shift much like is the case when reducing weight.)
You want a higher SE? Install a higher stalling TQ converter. There really is no other effective way short of changing the internal gearing of the tranny.
