what mph does your a4 shift into 4th gear? if you floor your car what mph should it kick into last gear? mine doesnt seem to kick in last gear it seems like it stays geared low for a long while.

3.23 or 2.73?? With my 3.23 it didn't shift into fourth gear until an indicated ~140 mph almost.
Use this: http://www.f-body.org/gears/
FYI: It took me 30 seconds to find that through searching. Entered gearing calculator and searched, first thread i clicked on i scrolled down till I saw a website......boom there it was.

If you have a converter it'll shift at a few mph lower due to the looseness of the stall. With my 3.42's and vig 3200 i think it hits 4th around 125, i can't say for sure, who's looking at the dash when doing 125?

At 100% tps, the stock shift point table says don't upshift from 3 to 4.
Here is a table I used for building/checking my shift points with 3.42 gears.
I ran it on up to 6700 rpms to match my limiter, but 6200 is the stock limit.
6700 is good for 201.8 mph in overdrive...

Hmm, maybe the older LS1 F-bodies had that, no 3-->4 shift. My 2001 SS used to shift into 4th at 135 with the stock converter, I have had my SS upto 160, just before the limiter. It was in 4th, the rpms came down after 135. Plus with my HPTuners program I verified the 3-->4 shift point, it is at 135MPH. I am not sure how my higher stall converter have affected this, since I have not made any top speed passes lately. 
K9KEV, look into HPTuners to adjust your shift points to where ever you want. This is a great software package at an affordable price!

But seriously, I'm thinkin that the 98-00 may not have been able to shift 3-4 without tuning.
I'm gonna look into the HP Tuner
Thanks
Mine would shift into 4th at 145mph @ 6300rpm with 3.23s. I haven't tried it since the gear swap, but I figure it's around 120 now since I'm turning ~ 6k ! 113 mph at the track (and I can take it up to 6500 rpm now).
