As long as you aren't going a speed that's going to over rev the motor then drop it into 2nd and hammer it.

make sure you give it gas when your downshifting or you can blow it up.

That basically what I did. Went from T56 to TH400. I still like t56 for normal street driving and somewhat spirited driving, but I really don't regret going TH400.
The wheels up launchs >>> rowing gears. And replacing clutches gets old fast...

And who needs overdrive, it just means you'll spend more money in gas. Which do you want to do, spend money on gas, or money on clutches?

Im also curious on this topic, wanting to do this myself. sidewayz28 what size stall are you using and what are your RPM's on the highway etc?

sidewayz28

iTrader: (24)

i dont have the exact specs on the stall. but its a 10" rebuilt Yank, and i was told its a 3400+

my rpms are JUST shy of 3k at 60mph with 3.42 gears

LS1? Thats alittle too high for me, I still wanna be able to get up to 100mph without blowin my **** up.

sidewayz28

iTrader: (24)

yes, ls1. High way driving is completely different w/ the th400.. sucks compared to T56. My car isn't my daily, and i would have never swapped if it was. I havent really felt 1st gear with the th400 yet cause im on shitty sumitomo 315s.

Unless you have another car to drive or the Camaro is gonna be raced at the track a lot I wouldn't get an A3.

I'd do a 4l80E swap before I did a TH400/350. I'd stick with the T56 until you smoke it. Unless you go to the track like every weekend or something.

With 3.91's and an A4 w/ 26" tires that's as aggressive as I am willing to go (2500 @ 70mph). I couldn't even imagine not having OD and ever driving that setup on the hwy.

Th400 w/ no lockup, you would probably be spinning at 3300-3400 at 65 with 3.42's.

T56 with the right clutch can take a H/C car with up to 150 shot. Like said earlier though it will lack consistency.
