Im just wondering cant find anything what is the name for the auto trannys in the 06 cobalts? Its like 4t-some thing

 

hello/bump

 

I believe its 4T45-E wouldnt know for sure since I believe the "upgraded" automatic is actually a huge downgrade on these cars, and I would never be caught dead driving one. My 5 speed LS was almost 3 seconds faster at the 1/4 mile track then my parents Auto LS.

 

Not with an autotrans intercepter its faster and can handle more HP look it up on the net its prety interesting.

But if I wana shift Ill fire up the camero and go fast at the same time. and I like my auto because its my gerocery getter.


And thanks for the info

 

How much did it run you to port and polish the head?

 

Yes, it is the 4T45E

Automatics in general are typically slower than the manual versions cause they are complex and have more of a process inside the transmission than a manual, which makes them lose more power during the transfer to the wheels.

 

I know autos suck until you start pushing high hp numbers.

 

That's false actually.

An auto trans interceptor only improves your shifts by increasing your line pressure...thats it.
You'll still experience just about the same drivetrain loss as you did before.

 

It acualy will just because of the fact that the tc will ingage stronger and slip less making it faster in the 1/4 mile than before.

And i do know that autos lose power in the TC from spin off and slip

 

3 seconds?? Did you even take your parents balt to the track??

A stock Automatic LS Sedan runs 16.6, verified by Car & Driver, thats a long shot off from the 3 seconds you seem to think

 

Actually It doesnt improve the 1/4 mile ET very much, it feels more solid but it doesnt help much. To get the most out of an Autotrans Interceptor, I'd recommend poly mounts all around. I've heard many stories of Line Pressure upgrades of how it did Jack-Sh*t in the 1/4

 

The intercepter with some one who knows how to set the Tork Converter delay setting has shown arond 2/10 off the quartermile in a cavy so ill see how it goes on a cobalt.


Polys are coming soon or an ingalls or both.

 

Not being rude but it's "Torque" not "Tork"

Also, 2/10 could be anything...could be his launching, could be the weather outside, could be less humidity, could be the temperature...that 2/10 could be anything.

Take it from someone who HAS owned a car with it, there isn't much adjusting you need to do. It just makes your transmission shifter harder and more solid...thats it! You're not setting your "torque converter delay setting"...I don't even know what that means.

 

He's talking about the Overdrive delay in the torque converter where the Torque converter locks up completely

 

Thanks for the spelling leson but if you take the back cover off the autotrans intercepter theres a second setting you can mess with it is the TC delay it changes the time that it takes the TC to fully lock some one told me that stock is like 5 seconds?

 

Unfortunately, I don't have my car anymore and nor do I have the interceptor to see what you're talking about.

 

No, no. There is no time specific delay to converter lock. It is torque specific and controlled electronically by the TCM. HP Tuners allows you much better control of the 4T45E tuning parameters.

 

I didn't think there was on the interceptor.

So my question is, who told him that there was?
