c6 2005 automatic

Have a C6 o5 Automatic I noticed that it doesn't go over 2000 rpms is this normal , it has power took it up to 120 mph but it just seems weird , I don't not have it in competition mode any ideas , it shifts fine will I think it does as it feels like its stuck in one gear and doesn't downshift at all

Sorry, but to go 120 mph you had to go over 2k rpms. Your post makes no sense.

Are you saying it wont go above 2k in any gears but OD?

" it shifts fine will I think it does as it feels like its stuck in one gear and doesn't downshift at all"

Does it shift or is it stuck in one gear? If it doesn't downshift, what gear is it in?

Gonna need some more facts. Starting from a standstill accelerating up to speed, what exactly does it do? What does it do under hard throttle from a roll?

Yes, this post is puzzling, even if it was stuck in 4th, it would definitely get (a smidge) over 2000 rpms at freeway speeds. Anything over 80 would be considerably higher.

If you don't shift "manually" it will still go from 1-2-3-4 in D. And when you decelerate, it won't noticeably "downshift" when in D. When you come to a stop (or near) it should engage a lower gear to accelerate.

Did you ever get it fixed?

Did you ever get this resolved? My vette does the same thing. It feels like it starts in 3rd or 4th. It wont downshift or start in 1st even if I put the shifter in first.

The band might be broken.....or a leak in the servo....

Just happened to my tahoe.

Or a shift solenoid....

Checking the condition and level of the fluid would be first.... Then check codes.....

Call me if you're stuck.

A4 is a great trans in 2005.... Round here, We make em SING!

The A4 is a great trans if you tune it right.

I concur..
the wife loves the way the trans is shifting in her 05 now
certainly made an improvement
still have more datalogs to make, but certainly much more improved

Cool thing is.....The A4 tune is great, but when you add CoW BOOSTER! is also makes very

positive improvements to the way the trans behaves (without further trans tuning) because the

A4 and A6 transmissions shift behavior is modified by how much the driver presses on the throttle.....

Pressing the throttle MORE tells the trans you expect more... Funny thing is that the CoW BOOSTER!

gives you soooo much more when you press much less that it actually has a favorable effect on how and

when the transmission shifts.... Extra bonuses for FREE!

I love it!
