40mph Punch=dead Hole

Sup guys. My A4 sucks from 40 MPH. I kill anything on the road from below 30 and from 60+. Is there any way to help this, or is a torque converter the only way?

HOLLA IF YA HERE ME

Mine's the same way, I guess it's just the gearing.

You're dropping form a 3.06 first gear to a 1.60 second gear.

Get a high stall converter and you'll keep your RPM's up during that big dip.

Get an M6! ;) I love 2nd gear. :D

On my LT1 I had exactally the same problem, at some speeds,around 40MPH is one of them, You punch it, its just a dog. Yes at low RPM's its like I am waiting for it get get near 3500 RPM's.

I installed a Vigilante 2800 on the A4, and to tell ya the truth, it was like an act of god. Any time I got on it, at any speed it usually flashed up to 3700 RPM. It was amazing. AT highway speeds the TQ would lock up and it felt normal, but if I step on it, It just downshifts and the motor came alive.

I am going to put a Vigilante in my 00' Formula in 2 weeks, I know 1st hand that this will solve that issue.

nice keep me informed on how it goes. What does it cost to get a Torque converter installed?

I ran a car w/a small converter for over 11 years. When you get up in higher speeds and higher gears, it won't do a thing for ya. Get some steeper gears.

Who was talking about higher speeds and higher gears?????:confused:

I have a Yank ST3800 in the 00 Formula and there isn't a dead spot anywhere because even if it is at a point where it won't down shift it still flashes to 4000rpm or so and hauls butt.

Welcome to the world of the A4 trannny. By their nature, they have a dead spot.

A good TC will help your problem and you will notice an immediate difference.

Thats odd.. just playing around, my A4 feels strong holding 2nd gear around 30-40... the best power i get from 2nd.
What gears do you have? (mine are stock 3.23s)

It's usually very cheap. Any tranny shop can do it, it's basically removing and reinstalling the transmission. You could probably get someone that works on cars to do it for a couple cases of beer.

I know this is an old thread, but I found it with the "search" function.

I think I have the same problem. I was thinking it was stumbling from something electrical or maybe minor wheelhop, but the more I read this thread, it sounds like what I'm going through.

The window from 40mph to 50mph is horrible to punch it. It bogs for 1/2 a sec. Anything slower or faster is great.

Notice this after I rebuilt the tranny and changed gears in the back. Here's my set up:

2200 stall
3.73s
speedo reprogrammed for 3.73s

I only notice it if I'm in 4th gear. I can feel the 3-4 shift and then know I'm in this ugly dead spot.

Would reprogramming shift points fix this, or will it just move the "dead spot"? How about a higher stall..I've seen people talk about it in this thread...did that fix the problem?

You probably have 2.73's. Knock the shifter into 1st and enjoy :D
