RPM's at Highway speeds?
 

Im just curious what everyone's car runs for rpm's at 65. My is around 3200 :confused: . Just curious if that sounds about right? Seems kinda steep for a 700r4.

Try this. Might help.

I'd be willing to bet your trans isn't going into od, it's probably an electric lockup, and if the converter won't lock up it won't shift to od.Painfull wireing makes a kit for it

Gear ratio and tire size needed. If the gearing was 3.08 it might be close in a third gen. More info and it can be checked.

at 65 in 6th gear im at like... 1700 rpm.haha.

do you have gears?

Im at like 2000

I called the shop that built my tranny and they said that it is an electronic lockup. They said that I could just put a toggle switch on the dash or something to that effect. He also said that there are kits for it so that if you step on the brake and such it will shut off. I'm not a scholar when it comes to transmissions but hopefully I can get it figured out. Where could I get one of those kits?

check with jegs and summit (the company is painless wireing, but if you ever use one of their wiring harnesses for a full car it's far from painless)

dude u might have rear end gears put in. i have 4.10s in my stang and mine is at 3,000 at 65

1,400 at 65

I don't hit 2,000 until I'm going 85.

This is with a six speed and 3.42's.

idk how your RPMs are lower than mine, i have 3.23's.lol

A4 with a 4000 stall and 3.73's

2300 @ 80 mph

his trans won't shift to od without the converter lockup engaged

1650 @ 65 while still increasing speed.

Well, I figured it out. My tach that was in my car was calibrated for a v-6 :banghead: , so I put in an aftermarket under my cowl so I can keep the interior of the car looking stock, but I can still read the tach under the hood. Now it says that im at 2500 @ 75mph :) . Now all I need to do is get the tranny to lock up and I'll be set. Speaking of which, does anyone know or would recommend. I stopped into a local trannyshop and told them my problem about my tranny not locking up electronically. He said that he could get it hooked up electronically, he'd just have to drop the pan and see what wires were doing what. Or else he said that he could put in a hydraulic lockup so that the tranny wouldn't need any wires running to it period. If it was your car what would you do. Thanks for the input everyone.
