the throttle?

i thought it was in the transmission, but i could be wrong

Sounds like you are talking about the shift programming of the transmission. Some cars have Normal/Sport modes that change the shift points, and I'm sure there are people replacing chips or reprogramming them for specific shift characteristics. Is that something like what you are talking about? Because if not, I have no clue.

this this going to turn in to a spam thread?



I am getting that vibe!



if not could we have a little more info?

i think setec knows what im talking about..but bigjim, from what i heard..if you have an automatic transmission, it is something that instead of making the car shift around 3 or 4 rpms, it makes the car redline everything, and from what i hear its like racing with a manual, but the car does the work

 

[Setec Astronomy]

Um...back in the pre-electronics days we used to call this a "shift kit" which modified the hydraulics in the transmission. There was also something called a "kickdown linkage" back in those dark carbureted days...



My auto transmissions typically upshift at higher than 3 or 4 rpm, but with a modern car, if you've got your foot to the floor, you should be upshifting at pretty close to redline, anyway. What kind of car are we talking about?

I would have thought he meant the computer limiter...

Oh, THAT. You just break that off.

 

[BigJimZ28]

why whould you want it to redline?



all of my cars have a shift kit, higher stall converters



my 81 Z28 has kickdown linkage but I perfer to down shift manually with my Hurst Quater stick



and my 97 I have a larger (corvette ) servo & I can adjust the shift point and firmness, with a hand held programmer



What kind of car and what do you want it to do?

 

[pbfreak9999]

its ws6 trans am, i got it automatic because i could not find a manual for a good price. Im looking for something to unleash the automatic, what is there to do to it

Well then that easy(because I know a little about them )



I like to start with a stall converter but you can do any or all of these



a higher stall converter will allow the engine to rev a little higher off the line

and therefore put it closser to it powerband....this will give you a slingshot effect out off the hole!



as far as the shift point and firmness goes there are two options

on is a shift kit installed in the transmission and the other is to have the computer programmed



also you will get more out of a mail order tune then you will get with a hand held programer



the the 4L60E also has a external servo that will firm up the 1-2 shift



also check out:

ls1tech.com for some good info



pcmforless.com for your tune



performabuilt.com if you want a nice tranny built for you



also it sound like this is a must read you you:

wow thanks bigjim, that was extremely helpful, thank u alot, really appreciated

 

[BigJimZ28]

No problem glad I could help



also not transmission related but if the car is a conv. or has t-tops sub-frame connectors are a must!

check out UMI weld in's on ebay

they will take a lot of flex out of the car and make it handle a lot better

FYI these are for non conv. only

A buddy of mine has a setup for what your looking to do.

a hypertech power programmer will be a good starter for what you want to do.

Stall converter... next... or depending on what and how much your looking for either a shift kit, or a built tranny with a shift kit already installed that will hold more power...



Are you planning on running spray?



and like bigjim said which i would say is mandatory is the subframe connectors...

not to start anything here but a mail order tune will cost about 1/2-1/3 of a hypercrap

and give much better results
