What MPH should 3rd gear take me to?
I was out for alittle cruise tonite and I decided to get on it on a straight smooth highway where theres no cops. 3rd is only taking me to about 110mph or so, after that is OD. shouldnt it go higher. I didnt think that the stall and 3.73's would kill my top end like that. whats gonna happen when install some juice. N/A I went 108 in hot weather. I dont want the car to go into OD at the track when I start sraying how much will going to a slightly taller tire help?

I can't tell you exactly where but I know with my 3.23's and vig3200 it's just over 120 with a 6500rpm redline. i had thought about a lockup switch for a while to extend it a bit because of PI being notorious for inefficiency but they add a lot of stress to the tranny i heard.

with stock 3.23s with stock converter in my 99 z28, 3rd gear would hold til 140 mph. That's if you had it in 3rd, not OD, in OD it'll shift out at about 130.
with 4.10s with the stock and tci 3500, it'll shift out of 3rd at 110. at 145mph im at about 5600rpms in 4th.

Also there is no way a 3.23 gear will run you that high. My car is also a stock 3.23 car and it will want to go into OD around 120.

3.23 were a performance option for Z28, T/A, and Firebirds. Standard on SS and WS6.
