I got my 408 running but driving it I HATE...Since I went way over my budget I was still able to do a couple upgrades to the A4...2&4 super servos, Trans go kit and cooler with fan...

I went full race shift kit and still the stall feels so loose. Car hardly moves until 4k then wow. But who is at 4k on the streets in "normal driving" all the driving is 2-3k. Hardly feel the 1-2 shift. So I think this Fuddle is a piece of ****!! Never mind the 30day drauma I had just to get it back.

I've been thinking VERY hard about the m6 conversion. But don't want to spend the time/$$. I'd consider dumping this TC if I can get the feel I want. I want a car I hit the gas and go.

Can anyone give me advise??? I've got a 3.42 rear with the 408 so this should be a ton of fun.

Looking to redo the stall in June if I can get the feel I want...

 

You certainly can get a stall with a better feel and manors from any sponsor here.
Biggest thing is you need to determine what you performance goals are and what your are willing or not willing to sacrafice drivability wise to get them.

 

Drivability is KEY... I may have tops 2-3 track visits a year. Fun is the other key. Since the 408 makes great TQ I don't need to rev super high to get the fun factor. Its not a race car. For me hit the gas and go is the most important.

 

Then my personal suggestion others may be different would be a 3200 stall with a low STR

 

You can definitely get a converter that would make the car more street-able and not loose to much at the track. I would suggest our 2C stall, it would be about a 3400 in your setup. But you could probably only footbrake it to about 2500, that gives you an idea on how well it moves the car at low speed. When you are on it it will still flash nicely and with the torque curve you have will still pull hard.

Thanks guys!

Glad to know its not me and this crappy stall is the issue.

I've decided to go with you performa for my trans build. Thing is I'll have to wait. Just spent 9k so I'll need to save.

 

good luck man, dont give up on the auto so quick. let one of the sponsers hook you up with a converter that doesn't go to 4K before the car starts moving WTF is that about?

 

Yeah, it sounds like you just way overstalled your car. Picking up a lower one should make it a lot better. What is your current stall rating btw?

 

Current stall is 3200 but final stall is about 4k.

 

sounds like a very loose converter i have a yank ss3600 and i love it its got great street manners but when you lay her on the floor look out

 

eh its the fuddle... stay away

all the sponsors that posted are a great choice, i personally went with FTI

 

i kinda have the same issue with my stall, im running a ss4000 and its extremely loose. My car also baely moves till you get in the rpms and it flashes 5500

 

Ryan you have a pm.

Maybe I'm off base, but did you make double sure on the fluid level. I had this issue one time with a 3600 vigilnte, and it ended up being a pinched hose on the overflow causing the fluid level to look higher than it actually was. After I got the level right the converter didn't feel near as loose.

 

yeah the A4s can do some stupid things with fluid being low. As dumb as it sounds, just double check everything, cause Ive never heard of any of the reputable stalls requiring 4K to even get moving. HMMM!

 

Never seen anyone post anything bad about the SS4000, everyone ive seen running them seems to love their street manors and driveability. HMMM

 

Update the fluid was a little low. Just under a qt. BUT now I have no third! So I'm done with the trans. Looking into a rebuild. I've got like 25 miles on my 408 and have yet to feel any power. Yet it sits in my garage just looking sexy but not puting out

 

Don't give up yet. Get it scanned first. You converter might have forced a code disabling the 2-3 shift. The tuner tunes that out. I recall it's the misfire table. Or it could also be something as simple as the shift solenoids (about $20 a piece).

Log in and so a search on '2 - 3 shift' Titles Only or start here:

Since you only have 25 miles on your build IMO it's doubtful you toasted the transmission this quick.

I have a Yank PY3400 and it drives almost like stock but quickly has a completely different personality when I stick my foot in it.

My Z28 has a HC 347 with D1SC ATI at 8 lbs (565 RWHP) bolted to a Yank PY3400 Extreme followed up with a PeformaBuilt Level III. It's a heck of a combo - your 408 should be the same with the correct parts.

BTW : When you dyno'd the new motor for first tune - how did the TC react on the Dyno?

 

thanks dland.

25 miles on the set up. The trans I'm sure. I've had no dyno time yet. I had a tune loaded to be able to get the car to idle and drive at least to the dyno. BUT I can't get that far!! I'll scan for codes.

I did have the valve body down for the shift kit. I've done 3 of these before with no problems. I did break a shift solenoid but I replaced it with a ac delco.
I will check some more but my gut says its toast.

Thanks again!!!
