Default A4 manual shifting?

My first slushbox in a long time.....does not seem like any faster to shift 1-2-3 but how about shifting down to 3rd for around town? Seems like once it gets into 4th hard to get it to kick down. Was on a 1/8 mile circle track with it, a guy suggested leaving it in 2nd.

I am convinced it will shift when RPMs are right

Depends on what you want. When I had an auto (A4) and was in traffic, where I felt I needed more immediate response, I would put in 3rd otherwise I just left it alone. BTW, keeping it in 2nd is even more responsive but, as I recall, when locked in 2nd, it does not down-shift to 1st when you come to a stop.

In my experience the A4 takes longer to drop to 1st or 2nd from 4th (overdrive) than it does from 3rd. For that reason, anytime I believe I will need more power rapidly in the near future, such as anticipating a pass, I put the A4 in 3rd.

I always have it in 3rd leaving the Hot Pitts on a road course track, except for the one time that I forgot and had the A4 in Drive. For the first few minutes of that session I thought I was having a transmission problem because of the delayed down shifting exiting turns. Once I figured out that I had inadvertently entered the track in Drive, I put it in 3rd and all was well again.

On the other hand, around town and in traffic, Drive seems reasonably responsive to me.

Can 3 be used like D? That is can I come to a stop, will it downshift to 2 and 1?


So only 1 and 2 are like true low's that hold in gear?

I guess I have never driven the A4 that way to be sure on the answer, but I can tell you that if I get too slow, it will sure drop from 3rd to 1st (instead of 2nd) in the blink of an eye coming out of turn 11 at Laguna Seca at wide open throttle. For that reason, if I have my act together, I have to remember to manually shift to 2nd before going wide open throttle if I get too slow at this location. A drop to 1st at this location and at WOT breaks loose the rear tires, screwing up my line and exit speed.

I am thinking that the answer is yes, only 1st and 2nd hold in gear. I'll verify next time I'm out with the car.

When I need it to downshift I'll just move the lever to where I want it. Usually 2nd if I'm on the freeway behind a slow car. 2nd goes to like 90 so that gives me some passing power.

If it works the same as the 4l60e in my Tahoe, yes it uses all 3 gears. It just locks out overdrive.

I have 3.73 gears in my A4 and I never use D unless I'm on the highway at cruise speed. The response in 3rd with the 3.73 gears around town is phenomenal. I've heard you risk transmission damage dropping from OD to 2nd when you floor it. Mine up shifts and down shifts just fine in 3rd.

I've never really tried manually shifting my A4 - it has plenty of acceleration just stomping on the gas pedal. Something to consider would be to get a tune and have the shift points changed.

So maybe a dumb question, but I thought these auto's couldn't be shifted "manually" e.g. while driving without damaging something (unlike say a dual clutch auto). I thought you picked one and drove with it...

Only damage if you over- rev it.

Not sure if there is a fuel cutoff / rev limiter like more modern cars? My '12 Mustang would just fall flat once you came close to the rev limit.

Tried leaving it in 3 for local, not bad rev's stay around 2000 until about 55 so not much more wear, sounds better too!

I'm pretty sure he means if you are in high rpm in 3rd and move the shifter to 2nd then it will force the motor to spin faster than intended even if the fuel is cut.

This is what he means, but the cars computer won't let it do that.

Given the history of shift cable failures on A4 C5's I wouldn't think manually shifting gears around town is a good practice. Running in 3rd around town gives me more than ample acceleration and a click up to D when I get to cruise speed is easy on the cable.
