How much power can a ba 4 speed auto handle stock? I would like to keep the shifts like they are stock, not real interested in a hard shift driving in traffic. Also can performance mode be tuned differently to when it's in drive?

Mine tuned to 300rwkw lasted 12 months! About 30 passes and 30 dyno runs!

I've heard there a hit & miss box get a good one or crap one is your car tuned? What power you running? The softer the shifts the quicker your tranny will crap itself.

My car has never had full engagement at WOT above 320rwkw on the 2-3 shift,now I need to back off fully and let it slide in and get back on it.Once it slips once you will have hot spots on the clutches and will never get full clamp again,im on my 3rd stocky now in 16 months.

Get your S5 turned 1/3rd up and have moderate settings in the tune for firmness,my missus never complained with this setup and she's picky that way.

if you have the spare 3-4k then get it built tough and have a piece of mind mod with performance gain also.

My cars stock, I just wanted to know if I can up the power a little bit without building the auto. Does anyone know if you can make the shifts firmer in performance mode while leaving drive standard?

Mine held 300 for 12 months plus till I sold it.

Worms has held 300 for ages too.

I thrashed mine worm baby's his. Luck of the draw.

How about say 250? Would they stay fairly reliable?

Like said,luck of draw and driving style.No low rpm load ups with wide open throttle,no 4th gear heavy acelleration and keep fluid changes to 20,000kms max,I mean max.make sure a decent transcooler is fitted also,driving around in performace D is better for the box also when in less than 70 zones.

regarding shift firmness it will be fine for the other half mate,it only really clunks when slowly bringing speed up and changing at half or less throttle in manual mode.

my first tune was 264rwkw and trans lasted nearly 12months but gazzanats killed it,normal driving might have seen it still shifting so who nows.

Might just leave it stock then can't afford to be rebuilding trans every 12 months

Yea better save the money for your tampons then Brad.

Trying to save a deposit for a house don't want to spend money on the car just yet
