1999 A4 question

I have a 99 coupe with a A4 that has 75,000 miles on it my question is has anyone else ever felt this with theirs? when you put the car in Drive no O/d and go through the gears 1800 to 2000 RPM not WOT feel a slight shift real slight once in third gear it almost feels like it was shifting into overdrive, speed at this point is only about 55 miles in hour car is all stock and shifts fine during WOT. sounds weird but if I was to count the shifts including O/D it seems like the car has 6speed automatic, I know sounds crazy but?

thanks in advance for any input

what you're describing is the torque converter going into lockup...it's normal.

The only "fix" would be to tune out the 3rd gear TC lockup.
That can be done, but, as stated above, what you've got is normal and its the way GM setup the TC to work

It will feel like a new car.

Tune

I don't have an opinion on the torque converter lock up or not. However, Phil did tune my '00 w/ A4 and did a great job.

Thanks Dave,

I attended the advanced tuning school since I did your car, and we can still do alot more to the tune.

yep, happens in my 99 vert (85k)all of the time. i bought it used and it has a modified program because of cam and i always thought it had something to do with the program. seems to be an extra surge/shift sometimes at low throttle. no real issue with it, just different!
