Top Speed on Regular tranny?

[2000aleroff]

first off i want to say that i would never put it up to 140+ because its to dangerous. and i wouldnt do it on public roads. the only thing i would turn up the top speed for is if i were to race on a closed track

why do aleros comeout out 140mph speedos? ive always wondered since mine maxes out at 105. Is it just for looks?

Because when you top it out at 160+, it's more fun to have someone in a Z06 pace you so you know how fast you're going.

However, that's not the stock transmission. Mine's a 4t65HD with 2.93 FDR

Oh yeah, and I don't know what all that crazy crap is previously about disconnecting speed sensors etc. May not be that way on the 4-bangers, but I know in the V6 PCM, speed sensor input is required to establish shift points, cross-references to various other things, like TCC lockup, and would not be advisable to disconnect it or cut it off.
