I am planning for the future gtp tranny. Will it work. Downloaded a GM pdf file and the tranny number is the same. Gm list the parts required to make it very tough.

Thats good. The GM PDF file is the step by step procedure for turning your colbalt into a 1000 hp rocket. The PDF brakes it down into the require hp you are looking for all the way to 1000hp. The mods include every GM part number required to make the tranny bullet proof. Cooool....

Where is this PDF file?
BTW, are you sure the Cobalt has the same gear ratio at our HD trannies? Something to consider looking into.

Gear ratios can be changed....
If this is what I think it is..... This has been long awaited for.... They will be offering a differential that we've all been drooling over for better than a year. Comparable to the Quaife, or Torsen... Same concept being a Torque Biasing Differential.

Well, it's got my attention. Also, their differential will only have me drooling if it's affordable, unlike other models available.

Take a look and let me know what you think. Maybe its to much for the average racer but for those with the turbo and like to rip out the tranny.. http://www.gm.com/company/gmtunersource/html/race_shop_build_book.htm

From the PDF file
Starting with the heavy duty or supercharged application of the production transmission, the gearbox is modified into a three speed transmission with driver shift control utilizing an aftermarket performance torque converter. The changes have proven to be reliable behind a 600 hp engine and track proven behind a 1000+ hp ECOTEC engine.

I am sure there are some part number we can use to build up our trannies...here is another quote.
TCI and CompuShift offer automatic shift controllers that will operate the 4T65E Transmission. These are excellent choices for street strip applications. An inexpensive alternative for drag racing and occasional street use is the MSD Programmable shift controller part number 7559. (Fig. 234) This controller was developed to shift a Lenco type transmission. With a little ingenuity it can easily be adapted for use on the 4T65E transmission.

Any idea if we can use something like a Shrifter on the 4t65e?

Anybody? From what I saw, the Cobalt has to use a conversion plate for our tranny to bolt up to it. So, I'd say no.
